How to care for your laptop battery

Misunderstanding 1: The laptop battery does not need to be fully charged after the battery is fully charged

Lithium batteries are now used in laptop batteries. For lithium batteries, full use of a light battery for a long time will not have any effect at all, and it may even be harmful. Because lithium batteries do not have the so-called "buffer effect," only early nickel batteries have this feature. The life of a laptop battery is generally only related to human damage or natural life. Basically, the battery life is fixed, 300-600 times the number of charge and discharge, generally available for 2 years.

Misunderstanding 2: When the power is connected, the battery can be pulled out or not

Pulling and unplugging depend on the actual usage: The battery is not harmed when the DC power is connected and the battery is not removed, because the battery will not receive any power injection after it is fully charged, and the battery power will be directly transferred to the notebook power supply. Supply system. However, when the notebook is running at a high speed and the internal heat is too hot, it is better to remove the battery, otherwise it is harmful.

How to charge laptop battery properly

You should try to avoid the situation where the battery power is exhausted and recharged, because this will put a lot of pressure on the battery and cause damage. The more feasible approach is to charge at about 20-30% of the remaining power. In fact, the lithium battery of the notebook is limited in the number of "lighting/charging". All recharging with light will only greatly shorten the battery life. At the same time, the battery should be charged in a relatively dry place, and also pay attention to the problem of heat, which is the enemy of the battery.

Tip: The use of mobile phone batteries is not the same as the use of laptop batteries. Many people may judge according to the experience of using their mobile phone batteries, and think that laptop batteries should be fully recharged with light. This is not correct.

How to save long-term notebook battery

Is the laptop battery protected or should it be fully charged? The long-term preservation of the photocell will cause the cell to lose its activity and even cause the control circuit to become self-locking and can no longer be used. The long-term preservation will bring security risks. The best way to save the photocell is to use the electricity to about 40% and then save it. In a cool, dry place, about 20 degrees Celsius is the ideal storage temperature. Of course, it is better to take out the battery once a month, which can not only guarantee the good state of the battery, but also prevent the battery from being completely destroyed.

Some measures to extend the working time of laptop batteries

1> Turn down the screen brightness: Use fn + down / up key combination to quickly adjust the brightness (specific fn + which need to see their notebook).

2> Use standby, hibernation, and other functions: When the computer is not used for a long time, the notebook can be used for standby or hibernation, which saves power and extends the life of the computer.

3> Open cpu speedstep function, can greatly extend the battery's working time: cpu's speedstep function is activated by default in the BIOS, when using the battery, cpu will automatically use frequency down to achieve energy-saving purposes. If it is not turned on, you can press F2 to enter the BIOS to find Performance and set Speedstep Enable to Enabled.

4> When using the battery, try to turn off the wireless, Bluetooth, and infrared ports. At the same time remove unnecessary peripherals and avoid the use of large 3D programs, games, etc. to reduce unnecessary battery consumption.
