My battery stopped charging. It showed the status plugged in and charging but % doesn't increase. After performing the hard reboot i.e. removing battery and charger and then holding the power button for 30sec. It started charging. But again after 2-3hour if I connect the charger it doesn't on the main screen. But charges on the BIOS setup.

I just found out if you squeeze the center terminals in the charge port slightly together it will contact the communications line on the charger tip and correct the problem. Ive been fighting that for months.
I tried the Fn+F2 combination while in windows which turned which activated the battery to charge. I was also stumped on this too. Hope it works for you.
