Solved! laptop battery problem : fully charged when plugged but shut down when unplugged

[pkd7646]

Before start, I'm using msi laptop GT62VR 6RD.

One day, my laptop battery started to show "fully charged" whenever charger plugged.
But as soon as I unplug the charger, laptop's battery LED turns to red and shut down immediately.

I think this problem comes from wrong battery indicator. What should I do?

If you change the settings to not shut down regarless of battery state you will find out if its a battery fault or not.

Not sure if it's the battery or the board. I'm guessing it's the board, as the battery is reporting status. Try using a program to check the battery health, it might tell you something - otherwise you can take a chance on replacing the battery and hope that works.
