Forgetting to unplug the power occasionally won't damage the computer. But when the notebook is not in use, it is recommended to remember to unplug it as much as possible. In fact, the notebook battery has a chip and has the function of automatic control. So it doesn't matter if the laptop power adapter is always plugged in.
When it is turned off, if it is charging, the charging indicator light will generally be orange or flashing. When it is full, it turns green and always lights, and the control chip automatically disconnects the charging circuit. Even if the power is plugged in all the time, don't worry about the battery exploding.
Unplug the power supply has the following two advantages:
(1) Turn off the adapter, stop working and have a rest.
② Prevent accidental surge and damage to the adapter.
Extended data:
The key to storing energy in the battery lies in the lithium ion of the input voltage. The greater the charge, the greater the voltage intensity and pressure that a single lithium ion needs to bear.
Long-term overload will greatly reduce the life cycle of the battery. According to statistics, the battery of the same model can only maintain 300-500 healthy cycles if it is fully charged and discharged (100%). If the discharge starts at 70%, the number of healthy cycles jumps to 1200-2000.
The harm of connecting the power supply for a long time does not stop there. Batteries have a natural aging process, and high temperature will accelerate this process. The high temperature caused by intermittent charging will cause bubbles in the battery, which will have a fatal impact on the health of the battery. Therefore, we should not only pay attention to timely charging and discharging, but also pay attention to the working environment of the notebook to get timely heat dissipation.
