When the laptopis fully charged, it can be used for five or six hours, but some notebooks can no longer be charged after they run out of power. What on earth is this?
Power adapter failure：
In case of failure, the power adapter will not transmit current correctly, which will lead to a series of charging problems.
When the computer cannot be charged, first check whether the power adapter is faulty. If conditions permit, eliminate the possibility of power adapter failure.
Battery failure：
After confirming that the power adapter has no fault, you can choose to restart the computer, plug and unplug the battery again to check the fault, or use other software to check the hardware.
Replace the battery in time after finding the battery failure. In addition, you can also choose to restart the computer and enter BIOS mode, and select “Start Battery Calibration” in the Power project to repair the battery.
Problems with the laptop’s own software：
In order to prolong the battery life, many laptops will install corresponding power management software. Find the option of “battery protection mode” or “prohibit charging” in the power management software, and the charging will return to normal after restoring the system default value.
Main board or circuit fault：
If the computer still fails to work after the above series of tests, it is likely that the main board or circuit has failed. At this time, we should send the computer to the special maintenance office in time to repair or replace the corresponding hardware.
Use the computer correctly to prevent overcharging：
In order to avoid the recurrence of the same problem, it is necessary to master the correct computer use method. Generally, the battery of the computer will start to age after 3 years, so it needs to be treated and replaced in time.
In daily life, do not recharge the battery with dry power, and do not keep the computer in charge for a long time.
These are the solutions to the problem that the notebook battery cannot be charged. Have you learned? If you have any questions about computers, please leave a message and tell me at any time!
