Thanks for reading.
I have the dell laptop mentioned above. Earlier I was using it, looked away, and looked back down and it was off. I tried to turn it back on, no luck. The battery is dead so I can't boot off of it. Removed the battery and tried to boot off AC power. The blue light is on on the power cord, so it seems to be working, then as soon as I plug it into the port, the blue light goes off and of course the laptop won't boot.
What might be causing the issue?
