Whether the battery is unplugged or not depends on the actual use: unplugging the battery to connect to the DC power supply will not cause any damage to the battery, because after the battery is fully charged, it will not accept any power injection, and all the power will be directly transferred to the notebook power supply system. But when the notebook is running at high speed and the inside is overheated, it is best to take out the battery, otherwise it will be harmful.
2. Don't charge the notebook when it is dead.
Recharge the notebook battery after it is exhausted, which will cause some damage to the battery. If it is completely charged by photoelectric, the life of the notebook battery will be greatly reduced. It is recommended to charge the notebook battery when the power consumption is 20-30%.
3. How to keep the notebook battery unplugged for a long time?
If you plan to directly replace the notebook battery with the power adapter, it is recommended to use the notebook power to 40% and then store it in a cool and dry place. The most reasonable temperature is to avoid excessive temperature of 20 degrees. In order to prevent the notebook battery from being damaged due to power failure, it is recommended to take it out once a month to ensure that the battery is in a normal state. PS: Avoid running out of battery power, which will make the battery lose its activity and lead to the self-locking protection of the control circuit, which can not be used again.
4. Small coup to prolong the life of notebook battery
A. When using the battery, avoid starting large 3D programs and games, and remove unnecessary peripheral devices, such as CD and USB flash drives. Try to close the wireless, Bluetooth and infrared ports.
B. Reduce the screen brightness appropriately: you can use fn+ Down/Up key combination to quickly adjust the brightness (specifically. The fn+ key depends on your notebook).
C. Clever use of standby, hibernation and other functions: If you will leave the notebook for a long time, you can effectively save electricity and prolong the service life of the notebook by turning it off or leaving the notebook in standby or hibernation.
D. Turning on the speedstep function of cpu can greatly extend the working time of the battery: the speedstep function of cpu is turned on by default in bios, and when the battery is used, the CPU will automatically reduce the frequency and save energy. If it is not turned on, press F2 to find the performance in the BIOS and set Speedstep Enable to enable LED.
5. How long does the notebook battery discharge?
At present, most notebooks use lithium batteries. If the notebook battery is used frequently, it is recommended to discharge the battery every 2 months. Discharge the battery to 10- 15%, and then continue charging. If the battery is used less frequently, it is recommended to discharge it every 3 months.
If your notebook doesn't have special discharging software, you can follow the following steps:
Disable the screen saver;
● The power utilization scheme is set to? Always open? ;
In the alarm tab? Low battery alarm? Set to 10%, and set the operation to? No surgery? ;
● Will it? Severe power shortage alarm? Set it to 3%. What is the operation? Wait? ;
● Turn the screen brightness to the highest;
● Confirm that all windows have been closed and all previous work data have been saved;
● Unplug the power supply and all external devices after confirming that the battery is charged to more than 80%.
After the discharge, the notebook will be automatically turned off, and then plugged in to charge the notebook. This process can be repeated for 2 ~ 3 times, in order to make the battery continuously discharge with small current, which is impossible in our daily use, and its effect is basically the same as that of those special discharge software.
