1, software problems:
Many laptop brands have their own power management software. If battery protection mode is enabled, the power management software will prevent the battery from charging and discharging after detecting that the user is using AC power to extend the battery life.
Solution: When you find that your laptop does not charge, you can first enter the power management software, turn off the battery protection mode or cancel the no-charge option, if there are no other problems, the computer can be charged.
2, the hardware itself has problems:
If the battery itself is faulty, you can try to restart the computer and reinsert the battery to determine; If the battery is still unable to charge, you may wish to install some hardware detection applications to get a general battery loss reference information.
If it is determined that the battery hardware is faulty, do not open it or try to repair it, there is a certain risk, it is recommended to repair or replace the battery.
3, the power adapter problem:
There is a big possibility that the battery can not be charged is the power adapter problem, you can give the adapter to other normal computers to try to see if it can be charged, to determine the adapter problem after a new it.
4, the above reasons are likely to be caused by the motherboard failure, and the notebook caused by the motherboard failure is the most encountered notebook maintenance; The specific performance is that there is sometimes a power failure when the battery is not used, the power is disconnected when charging, and the power port can be judged by moving the power port manually, and the interface welding between the battery and the motherboard will also cause no charging failure; This can only be checked and repaired at the after-sales service point.
The computer cannot be charged in cold temperatures. This is a very normal computer, now are used lithium batteries, it still has certain requirements for temperature, if the temperature is too low, the battery will have a battery protection effect, so the charge will not be charged.
At this time, you can add a protective case to the computer to increase its temperature or put the computer in a warm environment indoors, when the ambient temperature is higher than 10 ° C, the computer will restore the normal charging rate.
