1. Turn off the computer.
2. Unplug the laptop battery charger.
3. Remove the computer battery.
4. Plug in the charger.
5. Press and hold the power button for about 30 seconds.
6. Insert the battery, plug in the charger and start the computer.
After performing the above operation, the device still says 'Plugged in, not charging', then the Network Administrator will "give up". The best solution at this point is probably to find a reputable computer repair center for assistance, because your battery may be faulty.
It should be noted, to increase laptop battery life, you should charge the battery and use it, then fully charge it again, doing so 3 times will help the battery work best. In addition, when you find that the laptop battery is bottled, is going to fail, try to recover and improve the performance of the laptop battery that has been subjected to the trick that the Network Administrator previously shared.
Good luck!
