How to care for laptop batteries

It is not a difficult task to have a notebook of your own, especially for the majority of students. Every year when the school begins in the fall, there will be a wave of crazy purchases. However, when you have your own laptop, do you care about how to properly maintain your laptop battery? How to properly and properly maintain your laptop battery is related to your experience in the future. The following small series will tell about this aspect.

First, make clear the two misunderstandings of laptop battery use:

1. Laptop batteries do not need to be fully charged before they are fully charged. The battery used in the notebook is a lithium battery. When the battery is fully charged for a long time, it will have no effect at all, and it may even be harmful. This is because lithium batteries do not have the so-called "buffer effect", and only early nickel batteries have this characteristic. 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, the general can be used for 2 years will end up.

2. When the power is connected, the battery can be pulled out or not. Depending on the actual situation: The battery is not harmed when the DC power source 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's power 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.

Then what should we pay attention to in the use of it?

1, correctly charge the laptop battery

As mentioned above, you should try to avoid the situation where the battery power is exhausted and recharged. 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.

2, the long-term unused laptop battery storage problems.

The best way to save it is to use about 40% of the electricity and then store 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.

In addition, pay attention to the following points to extend the battery life of your laptop.
1. Turn down the screen brightness: You can use the fn+ down/up key combination to quickly adjust the brightness (depending on the notebook operation).

2, good use of standby, hibernation and other functions: When not using a computer for a long time, can make the notebook standby or hibernate, which saves power and extends the life of the computer.

3, open the 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.
