It's some kind of internal issue. I've tried two different AC adapters that work and nothing. I know the computer is getting power from the adapter because it actually turns on (I can hear it and the CAPS LOCK key lights up). However, I don't get the chime or anything. It's not the HD cuz it doesn't have the blinking question mark it's just a black screen. I tried increasing the brightness but nothing.

Anyone have some other suggestions?
