I bought AO756 3months ago
and i changed HDD to SSD, and added more RAM
at first, it was perfect and awesome netbook ever.
but from.. about 1month ago, the battery wasn't chargable itself.

it's working under AC power.
and the word appears when mouse cursor is over on Windows' Tray charging Icon says
"전원 연결됨, 충전중" (Korean word. it means "under AC POWER, Charging now" )
and the external blue LED light (indicating charging state) is turned on.
BUT, the percentage is fixed on 85%.
and no change.
(if AC power removed, it goes down)
somebody said that, there're 3 major problems in this case
1. Adaptor
2. Charging board on Mainboard
3. Battery
SO, I tried that all.
changed adaptor, board, battery
BUT.. the problem is still remaining.;(
WHAT CAN I DO MORE IN THIS CASE
plz help me.
