The maintenance of notebook computer batteriesis very important, if maintenance or to the battery life has a great influence on, the following Suggestions to help you maximize extend battery life.
1, if you're using a laptop power when connected, then we should remove battery, long charging will damage against core. Similarly, switch on the power, even if the computer is closed and also to disconnect the battery, the reason is alexandrine.
2, if temporary need to use battery, so the battery power will run out in the former, switch on the power to recharge the battery.
3 if used batteries, a full battery, try to cut notebook computers and the power cord connection.
4, if long time not to use notebook computer batteries, should correct storage. Storage battery, the battery should not be full of electricity, but also cannot be state after discharge completely, the best state is battery power maintain at maximum capacity of the battery one-half of the store away. We suggest that stored in lower temperature environment, such as refrigerators in the fridge. High temperature can damage cells and will affect the battery life.
The laptop for a long time will be more and more dirty, especially screen and keyboard, to clear up also difficult, here to bring you the clean at ordinary times laptop computers and some hints. Battery maintenance
Notebook screen cleaning:
Notebook computer screen after using after period of time, can accumulate some fingerprints and dirt, this problem in mirror screen appears far more serious on, so often should wipe. But in the process of wiped screen, need to pay attention to:
1, do not use kitchen paper, wipe kleenex, etc, these material may screen scratch screen. It is best to use very fine fiber texture of fiber cloth to wipe.
2, wiping cloth dips in process of too much water, not cause damage to avoid screen edge.
3, don't use of alcohol solvent such as solvent, this to the surface coating display caused damage.
Notebook computer screen wipe it is best to use professional cleaning solution, everybody in buy laptop computers, be sure to ask for clean suits to dealers, that thing for dealers speaking, basic is a snip, don't white don't.
The keyboard aperture cleaning:
Although now laptop much adopted duckweed type keyboard, clear rise very convenient, but those who a year ago to buy laptops will meet some problems. Laptop keyboard after a period of use will accumulate many hair and dirt, cleaning is also required.
Power off your computer, above their heads gently shaking notebook (of course, keyboard down), so can shake some hiding in a laptop keyboard in the gaps of dust. If you have a clean clavier is special small vacuum cleaner, and use it to help clean up the surplus not shake, dust and dirt in stores, you can also find this small vacuum cleaner figure. Auxiliary can also use xiaomao brush to clean up the gaps between the key caps.
Clavier surface can use wet cloth to wipe, but carefully use corrosive solvent not bear. There is little need to pay attention to, the network has a cleaning method is to remove all the key cap, then swab clavier, the author suggested not this way, way more time-consuming, and secondly damage easily keyboard, the loss outweights the gain.
Here to tell you about each of the keyboard uses laptop keyboard.

Laptop keyboarddissembling method is a see two twist three scored, easy dismantling notebook keyboard:
The problems that plagued notebook clean all the keyboard, especially notebooks, clean up part is really troublesome, want to clean up words, the best way is to put down, but due to a keyboard manufacturer, the structure of the laptop is different today is different also, there are many net friend asked me how to remove laptop keyboard, because the brand is different, it's difficult, and one answer just to say also said it was not clear. Therefore we specially for you this book down several recruit, match on graphic interpretation, let you two minutes later he can tear open all over the world notebook, together and see it!
(keyboard cleaning issue has let users headaches)
Before the dissembling we first have to determine the laptop keyboard, now encapsulation types of common basically has 3 kinds, one kind is embedded type fixed type, one kind is card buckled, and a fixed type is the screw type.
A, embedded type keyboard dissembling method.
This keyboard in the fixed way DELL business models and day fastens notebook, behind invisible from the fuselage fixed screw, the keyboard before dismantling the layering dismantle above.
This layering in the machine are usually have fixed behind screws.
S embedded type laptop keyboard disassembled
Then we can see fixed screw, keyboard, direct twist noises.then.
Second, in addition to baffle have screws besides, still a notebook with an inner pad and baffle was not using screws.
S card buckled down method. The type of keyboard
Below we'll see card against law keyboard buckle type, this kind of keyboard in Taiwan is a notebook.
Twist the fixed screw back.
S the screw type keyboard disassembled
The screw type keyboard notebook mainly appear in Occident models such as ThinkPad and HP among etc.
First, we from the most difficult place to start, first the notebooks with keyboard behind out, remove the four screws. Mark
Note, remove the screw with the keyboard symbol can be, a total of four star.
Remove screw, below the keyboard after cock, pay attention to the site up do not overexert.
Stay away from the lower part of the body the keyboard, then pulled down after the keyboard, but to pay attention to the following connecting data.
Turned up on the keyboard, memory slots, boards and CPU radiator will appear in sight.
?Read and after you must to his own hands down, come a nodding acquaintance with notebooks laptop keyboard so simple.
Computer use CPU believe that everybody knows, but in other machines used the CPU may know, few people below to introduce the CPU applications.
"CPU applicable type" refers to the processor, applicable application type according to different users of different needs and different application van circumference, CPU is designed to different types, namely into embedded and general type, micro control type. Embedded CPU is mainly used in specific areas oriented MRT line special procedures, equipped with lightweight operating system, it is widely used, like mobile phones, DVD, STB, etc are using embedded CPU. Micro control type CPU is mainly used in automotive air conditioning, automatic machinery auto-controlling equipment field. And general type CPU GaoYaFu mainly used in pursuit of high performance, high performance personal computer system (i.e. PC desktop), server (workstation) and notebook 3 kinds.
Desktop CPU, is ordinary mentioned most applications used in PC CPU, say usually intel-based pentium 4, AthlonXP cy young, AMD etc, are all belong to such CPU.
Applied to the server and workstation for the CPU, because its application scope, so such CPU in stability, processing speed, while the number of processing task requirements are higher than standalone CPU. Which server (workstation) CPU high reliability is ordinary CPU could comprehend, because most of the server must meet 24 hours a day, 7 days a week full load workers make the request. Because the server (workstation) data capacity is very big, need to adopt more CPU parallel processing structure, namely a server installation of 2, 4, 8 and so on many CPU, you need to be aware that parallel structure need the CPU must for even a. For more on the server, the processor can used for database processing one-stop load high speed applications. Ultra high molecular weight polyethylene board for workstation, multiprocessor systems could be used to 3d graphics and animation files coding single processor unable to realize high processing speed applications. Another outside, many CPU new technology, are taken the lead in developing applied to server (workstation) the CPU.
In the earliest CPU design, and no single notebook cpus, all use desktop CPU. Later, as the pen of heat and remember this computer become the bottleneck of volume when the development, it gradually produce notebook special CPU. The internal space, by laptop cooling and battery capacity limitation, notebook in appearance size, power CPU (power consumption) have high requirements. Zengbaiji laptop battery performance is very important performance, CPU power of the battery life size, have the most immediate impact. So, in order to reduce power consumption, notebook processors contains some energy saving technology. In the wireless network will get more applications now, notebook CPU added some custom for wireless communication function.
Server CPU and notebook CPU, are included with their own unique proprietary technology, all is for the sake of better in their respective work under the pieces play better performance. For example, server, and more CPU parallel processing hypercore multithreading technology; Notebook CPU can be automatically adjusted SpeedStep (working frequency and voltage) energy-saving technology
Packaging mode, the three have differences. Notebook CPU is the smallest of the three thin one kind, because notebook processors volume need more small, high temperature resistant properties to better, therefore in the manufacturing process requirements also is higher.
Three of the stability on the server, because its design CPU strongest when they require a very low error rates, the partial products even demand year-round, fault time doesn't work loads more than five minutes.
Desktop CPU working voltage and power consumption is higher than the notebook CPU, usually desktop CPU test for 75 degrees Celsius, the temperature limit over 75 degrees Celsius, aerial spiderman operations will be unstable, appear even problem; While the laptop cpus for 100 degrees Celsius temperature limit test; Server CPU needs time for stability and requirements on cooling is higher.
In the choose and buy the machine especially specific functions computer (such as notebook, server) when, need to pay attention to the CPU is not suitable for such type, choose the CPU type, on the one hand, can affect the system performance, and on the other hand will increase the computer maintenance costs. Single CPU, of choose and buy must also note the applicable types, it is recommended that CPU according to specific application needs to buy the CPU.
Computer keyboard kinds too much, how to bring everybody below classification, the classification of meet the keyboard.
The keyboard is the most common computer input device, it is widely used in microcomputer and various terminal equipment. The computer to computer via a keyboard operator input various commands, data, command the work of a computer. Computer operating condition of the output to monitor, the operator can easily use keyboard and screen and computer dialogue, revising the procedure, editing, control and observe the computer operation.
Market research is as follows: the classification roughly keyboard
1. The keyboard, many different kinds of touch point, can generally be divided into two types and micro-motor type by the two former metal contacts on or off to the input signal, the latter by hall effect switch (using magnetic field changes) and capacitor switching (using current and voltage change) produce the input signal.
2. from coding the function, the keyboard and can be divided into full coding keyboard and the coding keyboard two kinds.
The keyboard is completed by the hardware encoding keyboard identification function, it through the identification key whether press and press the key position, by the coding circuit corresponding coding produced a unique information, such as ASCII). The coding the keyboard is by software keyboard identification function, it USES simple hardware and a special set of keyboard coding procedure to identify key position, then by the CPU will position yards through the look-up table program convert corresponding coding information. The coding speed of the keyboard is relatively lower, but simple structure, and through the software can provide some key redefined very convenient.
3. according to the application can be divided into desktops keyboard, laptop, keyboard, keyboard, SuLu machine industrial computer keyboard, double accused of a keyboard, six classes of ultra-thin keyboard.
Double USB control keyboard, can a keyboard control two computers, a key 2 seconds switching shortcut convenience. At present, only domestic 3R brand.
General classification of desktop keyboard according to keystroke number, key working principle, the keyboard shape classification.
According to the work principle and key keyboard, different ways of can be divided into four kinds:
1, Mechanical keyboard (Mechanical) adopting similar metal non-contact switch, working principle is to make contacts with conduction or disconnected, simple process, noise, easy maintenance characteristic.
2, plastic film type keyboard (Membrane) keyboard consists of four layers inside without abrasion and realize. Its characteristic is low prices, low noise and low cost, captured market majority share.
3, Conductive Rubber pad (Conductive Rubber) contacts Conductive Rubber is through the structure connected. The keyboard has a layer of convex internal electric conductive rubber, each key is corresponding to a convex, when pressed put the following contacts through. This type of mechanical keyboard keyboard is market transition to film the keyboard product.
4, no contact electrostatic capacitive keyboard (Capacitives) use similar capacitive switch of principle, through the button to change the distance between electrodes caused changes and drive encoder capacitance capacity. Characteristic is no wear and sealing is better.
I believe most people can use a computer, but really understand the configuration of the computer may not have a few, here to teach you how to configure the computer to see
.
The configuration of the computer, mainly to see the CPU, graphics card, motherboard, memory, hard drives, monitors, etc., while the notebook to see if its products
License on the line. Evaluation criteria 1, CPU, this mainly depends on the frequency and the secondary cache, the higher the frequency, the greater the secondary cache, the faster the CPU will be the future
Three levels of cache, four caches, etc., all affect the response speed. 2, memory, memory access speed depends on the interface, quantity and storage size of the particles (including the memory interface, such as:
SDRAM133, DDR233, DDR2-533, DDR3-800), in general, larger memory, the stronger the ability to process data, the speed to
Faster. 3, motherboards, mainly processing chips, such as: laptop i965 chip processing power than the i945, i945 than the i910 chip
In the data processing capability and stronger, and so on. 4, hard disk, hard drive in daily use, consider the less certain, but there is some impact, first, hard drive transfer
Speed (sub: high-speed hard disk drives and low-speed, high-speed hard disk is generally used in large servers, such as: 10,000 rpm, 15,000 rpm; low
Hard drive used in the general computer, including laptop computers), desktop computer for general use 7200, 5400 notebook computer for general use
This was mainly consider power consumption and heat dissipation reasons. Disk speed because of the interface is different at different rates, in general, sub-IDE and SATA (which is often said that the serial port) interfaces
Earlier, more than a IDE hard disk interface, by contrast, access speed slower than the SATA interface is more. Hard drive along with the development of the market, the cache has risen from the previous 2M 8M or greater, the same as CPU, cache, the greater the speed
Degree will be faster. 5 Video: The software running large response rate has a direct link, such as running CAD2007,
3DStudio, 3DMAX and other graphics software. Graphics in addition to the distinction between the hardware level, there are also "shared memory" technology exists, and
Generally comes in different memory chips, is the "shared memory" technology, you need to read memory from memory to handle the corresponding procedure
Needs. Or some call it: Dynamic memory. The technology used in notebook computers more. 6, power supply, that as long as enough power and stability, also OK 啦. 7, display: display interface with the motherboard the same impact, but people generally do not worry so much about. Software 1, the operating system: a simple example shows this: the same computer configuration, definitely better than running the original Windows 98 shipped
Line original Windows XP faster, and certainly surpasses the original XP running the original Windows Vista is faster, which shows the same
Configuration, software, system resources occupied by the larger, more slowly, whereas faster. Also, the English original English version of the operating system program to run the program than the Chinese version of the stability and speed have is off
Department. So, here is a special emphasis on the original system, that is, the system had not streamlined. Similarly, streamlined Windows-off
XP general, the speed will be faster than the original XP, because out of some not commonly used to streamline the procedure takes less system resources, the
To speed improved significantly. 2, software (including hardware) can be properly optimized to suit the user, such as: general office clerks, general configuration
Computer, install a streamlined version of XP and streamlined version of Office 2003 to meet its daily use. But if the graphic designers,
To require professional configuration, especially for the graphics card requirements, so, upgrade the software: Microsoft DirectX 9.0 or above
Is necessary. What software can check the computer configuration: 1, EVEREST 2 Master Lu Master + Optimization 3, rapid acquisition of hardware 4, cpu-z 5, gpu-z New version supports the latest Intel Core i5, and other new Core i7
Detailed Configuration
CPU Mainstream desktop CPU vendors are INTEL and AMD both. Low-end Intel platform is the Celeron and the Pentium series, the high end is cool
Core 2 (Duo has been successfully replaced by 1) in 2009 as the next generation of more advanced CPU I7 also listed, in the heart of this soon 32NM6 I9 also
Can be listed in 2011. AMD Sempron platform is the low end, high-end is the Athlon, Opteron. The most common is both low-end. INTEL processors
In the end there is e7400, can be used with higher frequency of DDR2 memory, and this is high-end AMD platform, it is difficult to achieve.
AMD64bitSP2500 + Although the value, but the lack of dual channel memory support, and this gives a lot of players feel uncomfortable. Intel and AMD configurations, there are two mainstream market. A configuration is an Intel, AMD configuration. The main difference is that
different cpu, cpu configuration definition is the Intel brand Intel, AMD, AMD cpu configuration of the brand. Products in the market given
The same position and performance. Prices are different, the main performance tend to differ. According to need and the price may be. Motherboard configuration Common good brand of fact, more than intel, Asus (ASUS), Gigabyte (GIGABYTE), Elite (ECS), MSI
(DFI) of these, there are some second-tier brands such as Spartak are also better. Memory Configuration There are 3 commonly used memory model: a) SDRAM memory cheat (that is plugged into the motherboard of the gold contact part) has two anti-
Stay gap, 168 pins. SDRAM in Chinese means "random dynamic memory." B) DDR memory is only one foolproof cheat
Gap, but slightly to one side, 184 pins. DDR Chinese means "double data rate random access memory." C) DDR2 memory
Goldfinger only a notch, but the notch in the middle, 240 pins. DDR2SDRAM 240 memory access cheat
Contacts. Memory 2009 has been upgraded to the latest DDR3 generation of memory, DDR3 memory to DDR2 memory is compatible, as adopted by the 240-pin,
DDR3 is the 8bit prefetch design, and DDR2 is 4bit prefetch, this is only the frequency of the kernel interface to DRAM frequency 1 / 8, DDR3-800's
Core operating frequency is only 100MHz. DDR3 mainstream operating frequency is 1333MHz. In 64-bit architecture for the frequency and obviously DDR3
Speed has more advantages, in addition, the DDR3 used in automatic self-refresh according to temperature, such as other local self refresh
Function, but also excellent in the power consumption is much DDR3. Line memory brand manufacturers have launched their own DDR3 memory, such as Kingston,
Apacer, A-DATA, Corsair, GeIL and so on. Drive configuration Divided by the hard disk interface: PATA hard drive interface is the earlier, 2009, where new production is basically the desktop can not see the;
This is the mainstream SATA interface, which is usually said that the serial interface on the market in general use this interface to the hard disk; SATAII This is
SATA interface, an upgraded version of the market there is also this hard drive is small, the main cache and the transmission speed is increased;
SCSI This is a hard drive used in the server interface, which is characterized by rotational speed can reach 10,000 rpm, so read and write speed
Degrees to speed up but also hot-swappable. Graphics cards Mainframe computer graphics as an important part of playing games and the like in the professional graphic design for people who were
Very important. Civil graphics including graphics chip supplier ATI and nVIDIA two. GPU Stands for Graphic Processing Unit, the Chinese translation for "graphics processor." NVIDIA GeForce publishing company
256 graphics chip Notebook
Graphics GPU to reduce the dependence on the CPU, and CPU for some of the original work, especially in the 3D graphics processing. The GPU
Core technologies used in the hardware T & l, cubic environment textures and vertex blending, texture mapping compression and bump mapping, dual texture
Four 256-pixel rendering engines, and hardware T & l GPU technology is a sign. Graphics card Graphics card (Display Card) is to control the fundamental role of the computer graphics output, connect the monitor by the graphics card
To be able to see the image on the display screen, display card graphics chip, video memory, RAMDAC and other components, these components determine
The output of the computer screen, including the screen displays the speed, color, and display resolution. A single graphics card from the early
Color video display card, color display card, enhanced graphics cards, up to VGA (Video Graphic Array) display graphics array
Are dominated by the IBM graphics card specifications. In text mode, VGA 720 * 400 resolution, the graphics mode is 640 * 480 * 16 colors
, Or 320 * 200 * 256 colors, and this 256-color display mode which became the common standard graphics card, so graphics card known as VGA.
Later, more committed to each graphics chip manufacturers to further enhance the VGA display capabilities, while SVGA (SuperVGA), XGA
(EXtended Graphic Array) and other terms appears, showing the chip maker is more to integrate 3D functionality and VGA, it becomes
The 3D accelerator known consistent, 3D graphics card. Pixel fill rate 3D pixel fill rate of the maximum number of clock multiplied by the rendering means. Such as NVIDIA's GeForce 2 GTS chip, nuclear
Center frequency of 200 MHz, 4 exaggerate the pipeline, each rendering pipeline with 2 texture units. It to the 4x2 pixel fill rate
x2 billion / sec = 16 billion pixels / sec. This form of pixels on the screen to see the screen, 800x600 resolution in the next, there were
800x600 = 480,000 pixels, and so there is resolution of 1024x768 1024x768 = 786,432 pixels. Playing games and
With some graphics software often set the resolution, while the higher resolution graphics chip will render more pixels, so a large filling ratio
Small for measuring the performance of a card of great significance. GTS's fill rate calculated above is 16 billion pixels / sec, and then look at MX200.
It is a standard core clock is 175, only two rendering pipelines, it's fill rate for the 2x2 pixel x1.75 billion / sec = 700,000,000 pixels / second
This is the difference between the performance of GTS than half of an important reason. Memory Short video memory. As the name suggests, its main function is to display the chip to be temporarily stored at Management of data and processed data. Stronger performance graphics core, the more memory required. Main memory before
Is the SDR, the capacity is not great. The DDR market are the basic specifications used in some high-end cards is using a performance more
As excellent or DDRIII behalf of DDRII memory (DDRIII is not even better, but the worst kind of). Two Interface Technology AGP Interface Accelerate Graphical Port, Intel developed a video interface technology standards to address PCI
Low-bandwidth bus interface technology developed. It is through the graphics card and connect the main system memory, the CPU and graphics processor
Opened directly between the faster bus. Its development through the AGP1.0 (AGP1X/2X), AGP2.0 (AGP4X), AGP3.0 (AGP8X).
The latest AGP8X its theoretical bandwidth of 2.1Gbit / sec. PCI Express Interface PCI Express is the next generation bus interface, and the use of such interface card products, was launched in 2004 has been
. Back in the spring of 2001, "Intel Developer Forum", proposed the use Intel's next-generation technology to replace the PCI total
Line and a variety of chips, internal connection, and called the third generation of I / O bus technology. Then in the end of 2001, including Intel, AMD,
DELL, IBM, including more than 20 industry-leading technology companies began to draft new specifications and completed in 2002, its official name
PCI Express. Theoretical speed of 10Gbit over, so in the gap, AGP PCIE has been almost hit, but as
Benq 52X keyboard adopts streamline modelling, ultra-thin big body design, the following share with you this kind of keyboard.
Recall 52M, catering to the beautiful vogue tide of ultra-thin 52G network, 52V slender, had left a good impression. Their common prevent water dustproof, supernormal resistance to knock sex also thoughtful.
The keyboard using circular doodle, streamline modelling with a removable chocolate color grind arenaceous Joe torre wrist, the wrist is short, modelling and put up with the keyboard shape more increased curvaceous. Anyhow the author put this keyboard after each visitor would heed it, and curious about, this effect, the author used so much before they did not meet the keyboard...
Feel is a more subjective thing, objective analysis, this type of keyboard feel slightly gelling, press down a bit like a comparative tight, some PinPaiJi keyboard handle, it and its bare-foot brother 52V opposite, make a big difference. This thought this keyboard struck voice will lighter.
No driver in WIN2K next can use shortcuts explanation of the keyboard from one after the other machines upshifting driving 98SE 2K, a touch on three shortcuts on the past. Pop-up IE, pop-up OUTLOOK is unexpected, the third semilobar is what? Is half horn all cape? Then the machine was when machine... * & % $# @ carefully look, original is dormant.

The computer more and more common in everyday applications, but the computer in a long time, opening opportunities for more and more slowly, here are some of the accelerated power method, we want to be useful.
One, BIOS settings optimized
In the BIOS setup page we enter the "Advanced BIOS Features" option, move the cursor to "Frist Boot Device" option, press "PageUP" and "PageDOWN" to choose, the default value of "Floppy", which means that the system starts will start with the floppy boot information is read, it would lengthen the machine's start-up time, and shorten the life of floppy drive. So we have to select "HDD-0" directly from the hard disk, so start soon Shanghao seconds. In addition, BIOS settings "Above 1MbMemoryTest" the proposed election "Disabled", for "QuickPowerOnSelftest" recommends that you select Enabled.
In the "Advanced Chipset Features" item in the set of the acceleration of the machine is very large, please take note. The "Bank 0 / 1 DRAM Timing" from "8ns/10ns" to "Fast" or "Turbo". "Turbo" than "Fast" faster, but less stable, the proposed election "Fast". If the memory of good quality can choose "Turbo" try, instability can be changed back to "Fast".
Quality of a good memory for the memory recommended "SDRAM CAS Latency" option is set to "2", which can speed up, oh.
Newer motherboards support AGP4X, if your graphics card also supports AGP4X, then in the "AGP-4XMode" to the activation at that selected as "Enabled", this will be a better ability to play cards, to speed up system Start speed.
Second, start the DMA mode, improve disk speed
Using UDMA/33, 66,100 technology drives maximum transfer rate is 33MB / s, 66MB / s, 100MB / s, is theoretically IDE hard drive (this is the PIO MODE4 model, the transfer rate is 16.6MB / s ) transfer rate of 3 to 6 times, but the default settings in Windows which, DMA is disabled, so we have to open it.
The specific method is: Open the "Control Panel → System → Device Manager" window, expand the "Disk Drives" branch, double-click the icon UDMA hard drive, go to "Properties → Settings → Options" in the "DMA" item in front of "√", then press OK to close all dialog boxes and restart your computer.
Third, remove the Windows boot logo.
First of all you have to open the "Start" → "Settings" → "Folder Options" from the "View" tab in the "Advanced Settings" list box, check "Show all files." Then open the C drive, find Msdos.sys this file, and cancel its "read only" attribute, open it, in the "Option" under the paragraph, add a line statement: LOGO = 0, so that Windows will not be the boot logo load operation, the boot time can be reduced 3 seconds.
Fourth, optimization "start" group.
Beginners love to try a variety of computer software, with a moment later pushed it removed, but often for some inexplicable reason, the software will reside in the "start" the project (especially in the use of some D version of the software ), Windows startup, will do a lot of time wasted. To solve this problem is very simple, you can open the "Start" → "Run" in the dialog box that appears "Open" field select input "msconfig", then click "OK" will bring up the "System Configuration Utility ", click on the" Start "label, will not have to load the program in front of the Startup group" √ "get rid of it. In this way, at least they can start-up time shortened by 10 seconds.
Fifth, organize and optimize the registry.
Windows in the boot, the system registry to read the relevant data and temporarily stored in RAM (memory), Windows boot most of the time, are spent in it. Therefore, sorting, and optimize the registry is very necessary. For optimization of the registry, you can use software such as Windows optimization master. To optimize the master of Windows, click on "Registration Information clean" → "scan", the software will automatically clean your registry for garbage, after the scan, it will pop up a menu lets you choose whether to back up the registry, the proposed option to back up, Backup and then click the "Clear" button.
Sixth, regular maintenance system.
If installed in the system too much of the game, too many applications, too many old data, make your computer run faster and slower, and the boot time longer. Therefore, the best time to time, on the computer to do a comprehensive maintenance. Click the "Start" → "Program" → "Accessories" → "System Tools" → "Maintenance Wizard", then click "OK" button on the computer to conduct a comprehensive maintenance, this would allow your computer to keep in top condition . For the hard drive is best to every 2 weeks to do a "Disk Defragmenter", that would significantly speed up the startup speed, click on "System Tools" → "Disk Defragmenter" can be. Note that the defragment the hard disk drive where the system must organize, in order to really speed up the Windows boot sequence.
Seven to expand the virtual memory capacity.
If your hard drive is large enough, then you open the "Control Panel" in the "system" in the "performance" options open "virtual memory", select the second item: the user set their own virtual memory settings, point to a less hard-disk drives, and the maximum and minimum values are set to a fixed value, the size of about 2 times the physical memory. Thus, when the hard disk virtual memory in use, would not yield to their suddenly big suddenly small difference, but will be fixed in the space as virtual memory, speed up the access speed. Best virtual memory setting in the "Disk Defragmenter" after, so virtual memory is not a sub-continuous, non-fragmented file space, you can better play a role.
VIII, remove the "wallpaper", "Screen Saver" and other fancy settings.
These settings are not that take up system resources, but also seriously affect the Windows boot sequence. Get rid of them is: Right-click in the desktop, the pop-up menu, select "Properties" in the pop-up dialog box, select the respective "background" and "Screen Saver" tab, the "wallpaper" and " Screen Saver "is set to" None "button.
September, delete Autoexec.bat and Config.sys.
System is installed under the root directory of the Autoexec.bat and Config.sys these two files, Windows no longer need them, you can safely remove them, which can speed up Windows startup speed.
Ten, to streamline *. ini file, especially the System.ini and Win.ini content.
In the system.ini in the [boot] and [386Enh] section add a lot of drivers and font files, is to remove the key. In particular, note that, [boot] shell = Explorer.exe field is hidden Trojan horse like the loading of, the Trojans are usually sentences into this: shell = Explorer.exe file.exe, pay attention here file.exe is a Trojan server program! With the Trojans then loaded to run not only a threat to security, the computer starts but also a lot slower; of Win.ini in the "Run" and "Load" back loaded, not every boot you must run the program, you can temporarily removed, so when the future use and then click Run. Windows calls this boot will reduce the number of relevant documents, will naturally start much faster speed.
XI, close the disk scan.
With a text editor to open msdos.sys, will see the following:
[Options]
bootmulti = 1
bootgui = 1
autoscan = 1
If you do not want to run after improper shutdown ScanDisk, can atuoscan = 1 to autoscan = 0, so that non-normal shutdown the computer will boot faster rate in some (not running because the scandisk thing.)
Second, to guide the shortest information retention time.
With a text editor to open msdos.sys, set the [Options] in the BootDelay is 0.
XIII, reduce unnecessary font files.
Font files take up more system resources, slow boot time and uses a lot of hard disk space. Therefore, minimize unnecessary font files. However, if deleting the wrong font files, they might make Windows not working properly. So you can use the following "back door" method (the installation of font files can be achieved without taking up large amounts of disk space): First open the font folder (such as F: zk), select all the TrueType font files, use the mouse the right to drag them into the C: Windows Fonts folder, the pop-up menu, select "Create Shortcut in the current position", so that the font in the system font folder, create a shortcut to the file . When you need to use these font files, as long as the font disc inserted when not out on it.
Fourth, by deleting the unwanted Dll files. System in the Window operating system there are many subdirectories Dll files, which may be a lot of file sharing, but some did not not have a file to use it, that these files are useless, in order not to take up hard disk space and improve the startup speed, can be deleted.
Fifth, "heresy" approach. Such as the use of the system hanging, about to shut down the current system state saved, the next boot, the system will go directly to the desktop before the last shutdown, using this method, the fastest boot time up to 4-5 seconds, but not all The motherboard BIOS support, set up and is also somewhat troublesome.
Open the registry, expand to HKEY_LOCAL_MACHINE SOFTWARE Microsoft Windows CurrentVersion SharedDlls sub-key, there are many on the right Dll files, if the data is 0, you can not determine the Dll file sharing program, you can delete it.
If done by the above methods is still not fast enough computer startup speed, in addition to upgrading the hardware (CPU, memory, hard drives, etc.), another good way is to reinstall the system, this can significantly speed up computer boot times.
IPad believe that everyone is familiar, underneath introduction tablet computer in enterprise applications.
The iPad has just listed in a few months, more than half the fortune 500 enterprises purchase iPad. Nowadays, smart phones and tablet computers have become more and more staff in carry-on.
Not far away from our Australian, Pizza Capers, Pizza company -- home have begun to use iPad to receive orders, but Jetstar also start trying to use the iPad to provide aviation entertainment services. At present, the secco atrium leads Curtin University of technology (more than 200 have been put into use iPad, and the CIO Nikoletatos believe that in the future, Peter 18 months, the University's 6,000 staff about one third of will use tablet computer.
New age mobile applications
People hope the mobile equipment satisfies the entertainment and work demand, and IT practitioners earlier in tablet computer work to see the value of related activities. Such examples in the global scope and lots more. For example, one of the world's most famous luxury car manufacturers are trying to make sales staff use tablet computer keep track of the latest information, and vehicle within in the exhibition hall 购车人 credit check; A U.S. major Banks are using tablet computer the telegraphic transfer millions of dollars for examination and approval; Medical experts also begin to use tablet computer check the patient's medical image and health records, and access to key medical applications. IT administrators can be used from any location tablet computer remote management and monitoring key business system; School everywhere students, teachers and professors will also tablet computer teaching for their daily life and an indispensable component.
Select a set of mobile users can meet the demand of the next 10 years wireless local area network (WLAN) solution is very important. As mobile terminal quickly become enterprise, hospitals, education institutions and retail, etc, the necessary equipment industry IT departments must ensure that its WLAN infrastructure to the overall cost of ownership at the lowest, meet employee to performance, integrity, expansibility, safety and mobility of various new demand.
Enterprise flat big challenge. 5
1. Expansibility: because Wi - Fi is tablet computer, the only way to realize connection for iPad or PlayBook such as without cable Ethernet port can depend on the tablet computer, Wi - Fi performance is very important. Design high-density wireless LAN, means that need to consider in tiny region have numerous tablet computer, smart phones and other Wi - Fi client equipment, you need to consider the restricted, or like a connection connection speed slower on performance influence.
2. Integration: iPad and upcomings PlayBook are adopting 802.11 n technology, so IT departments need to ensure that these high-performance equipment not to adopt traditional Wi - Fi technology client performance negative effects. In order to maximize the advantages of its tablet computer with traditional Wi - Fi technology part performance also need guaranteed. Should take corresponding measures to prevent overall network performance and existing wireless devices and applications performance reduced.
3. Safety: corporate IT departments in ensure enterprise how sensitive data protected while, can guarantee tablet computer users to easily access? Apple iPad PlayBook is different, with the main target is consumer, but because management personnel with the hope of enterprise application integration, therefore IT department must ensure that IT can reduce data loss or network attack risks to meet various regulations.
4. Mobility: users in the use of mobile devices, hope whenever and wherever can easily connected to the Internet. Therefore, the IT department must ensure that users can in different regions, including park office, even inside or shopping centers, hospitals and other regions move freely, and won't become disconnected, such ability won't affect employee.
5. Battery life: iPad battery life span is about six to ten hours, and dell Streak battery life for all day. The IT department must ensure that the design of the network infrastructure can maximize the extend the battery life of tablet computer, in order to improve the end user experience and productivity. Battery life is the key to realizing mobility, if the wireless network will quickly drained battery life, so the use of tablet PCS will be charging time limit.
Flat computers seems destined to become the bedside update patient record, in the hotel sales orders, on the road in the demo, retail checks inventory, notes in the speech chamber of such use a new way. With the popularization tablet computer, function is more and more abundant, improve IT and wireless needs must also keep up with!
At present, the laptop has sold more than desktop computer, smart phones is omnipresent. According to the research report by that has had 43 percent of enterprise staff in using wireless network, and the number is expected to rise until 2014 to 58 percent. The IT department needs prepared for mobile devices into enterprise wireless network era. No doubt, mobile enterprise already appeared, and as more and more technology staff by more and more intuitive and enterprise products faster wireless speed will only.
