Dell Inspiron n7010. Had set on hibernate, now will not power up at all. Tried the different methods of turning on (i.e. holding power key down for a minute while battery/AC adapter disconnected, connected, etc.). It's still just dead. Also, the AC adapter LED light shuts off when plugged into computer. Tried other adapters, same result.
Welcome to the Community.
It seems that there is a problem with the motherboard ( system board ) of your laptop. I would suggest you to get it replaced as it is not transferring the charge to the battery. Also, I would suggest you to check the port wherein you plug the ac adapter to see whether it is damaged or not.
