Now more and more people use laptop , how to maintain your laptop battery is also more and more people concern.Now we will talk about the content.

1: laptop batteries no need to be charged until it was out of power.

Now the laptop batteries are lithium battery, for lithium battery, there is no any role to charge for long time after it power off, or even harmful. Because Lithium battery does not exist the so-called "cache effect", only the early nickel battery just has this feature. Notebook battery life generally only with artificial damage or natural life. Basically speaking, the battery life is fixed, 300-600 times of charging and discharging, generally available in 2 years.

2:When the power connecting, the battery can be pulled out or not.

Pull out or not pull out depends on the actual usage: in the connection of the dc power supply at the same time not pull out the battery will not caused any damage to the battery, since the battery will not be accepted any electricity into when it's in full of electricity , electricity directly to all the power supply system of laptop. But when the notebook at high speed, and internal overheating it's better to remove battery, otherwise is harmful to battery.

3:How to charge laptop battery correctly ?

Should try to avoid charge battery after it run out power, because that will give the battery big pressure and cause damage. A feasible way is in the remaining 20-30% power then to charge. In fact notebook of lithium battery in the "light/charging the number of times" is limited, all run out of recharging will only shorten battery life. At the same time, the battery should be more dry place in charge, and to pay attention to heat problem, this is the great enemy of the battery.

4: How to save the laptop battery which is not used for a long ?

Should notebook battery be kept with power or without power? Battery run out of power to be kept for long time will caused core lose activity, and even lead to control circuit protection locking and can't use again, full of electricity long-term preservation will bring safe hidden danger, the most ideal save method is to use electricity to about 40% and then stored in a cool and dry place, about 20 degrees Celsius is the ideal temperature preservation. Of course, every month we need to take out the batteriy to use , which can ensure the battery good save state, and will not loss of power and damage to the battery.

5:Some measures of Extending laptop battery working time

1 > lower screen brightness: can use fn + down/up key combination fast to adjust the brightness (specific fn + which button needs to see their laptop).
2 > use standby, dormancy function: when a long time not using computers, can make your laptop standby or dormancy, already save electricity extended by the use of computers
Life.
3 > open CPU speedstep function, can greatly extended batteries work time: CPU speedstep function in the BIOS is the default start, when use the battery, the CPU will automatically fall frequency of use to the energy-saving objective. As no open, can according to boot into the BIOS Performance found in F2, setting
For Speedstep Enable Enabled.
4 > in the use of the battery, try to close the wireless, bluetooth and infrared port. At the same time use to remove the peripherals and avoid enable big 3 D programs,
The game etc, in order to reduce unnecessary battery consumption.
