Hi. My Acer Aspire 7750G stops charging after a little time playing games. The laptop turns the charging on and off fast one time, then after a little while after stops charging until i manually replug the powercord (pull it out then in again). When it stops carging the power and battery lights blinks continuously along with the on/off button, even after i shut the laptop off. The only thing that resets it is replugging the power cord. The laptop is not very varm, but it does seem to happen when the cooling fan starts working hard. Any idea what may cause this?
