I have an ASUS N53S laptop running Windows 7. It is plugged in to AC power, green light on power pack is on, but the computer is not acknowledging the AC power and the battery is about to run out. It was off and plugged in all night, so I was surprised to see low battery alert when turned on this a.m.
I have tried shutting down and restarting, unplugging from wall for over 1 minute, looking for settings that might tell it to run on battery only (can't find any). I run ESET NOD32 antivirus, which is up to date, so I'm hoping nothing got through.
Any help will be greatly appreciated.
