Laptop Charge troubleshoot

You might have erased the Cells memory to be able to charge it to full capacity... this happens when it is constantly plugged into power source and has battery in as well.... even though you're using AC power, the battery drains and eventually it's cell memory thinks that 80% is full....

Try doing a bios update ... if it's not the battery itself, a bios update might have a correction for it...

Hi there
Basically the battery was not fully discharged when it was brand new and now the battery thinks its fully charged at 80%.
In some laptops a cell may have failed but usually causes the battery not to charge at all.
Fully discharge the battery and see if it will resume a full charge, if not your stuck with it like that.

Good luck and thanks for using Fixya!!

This can be due to a dead cell in the battery pack,Could also be the charger is going bad or shutting off prematurely.
