LIke the title says, when the AC/DC adapter is plugged in the laptop power on and presents a bios error with one long beep and two short beeps (presumably video card problems), lights and coolers on but no video. When on battery alone it works and enters Windows like it should do.
Unfortunatelly my batery is dead and only lasts a minute, so even a backup is hard to do right now. When I power on the computer on battery, the boot is ongoing normally, if I plug the AC adapter the video imediatelly turns off and the computer remains unresponsive, lights and coolers on (the same failure). So clearly the error only happens with the AC plugged in.
I can open up the laptop if needed, already done it one time. I have a cheap digital multimeter and the 19V AC adapter is marking 19.6V, it charges normally the almost dead battery, confirmed by the battery charging lights on the laptop. Based on that I dont think the problem is the adapter itself, but something inside the laptop that runs after the Power Jack Plug.
This error was not sudden, it began slowly with crashes and it was increasing day by day until the computer no longer functions with the adapter plugged in. I thought my videocard was dead until I discover by accident the computer still functions on battery. My battery is almost dead, I did not use the laptop on battery for more than a year.
I would apreciate any help. Thx.
