A friend of mine has a sony vaio model pcg-61611L that was having issues. It will load windows fine. You can work for a few minutes then it shuts down. When I picked it up off the desk, it was really hot near where the power plug connector is. It will not turn back on until it is completely cool again. As its running, I can feel air being blown out so Iam sure the fan is working fine. It doesn't make any odd noises. I was thinking maybe a power supply issue since it is only hot near the power connector, but I don't know. Any ideas?
