I removed the battery, plugged in a new AC adapter (light glows solid around DC jack). When I press the power button it powers on, the fan spins up, then there is a quiet click sound from inside (near the DC jack area) and it immediately shuts down. I have removed the HDD, CD-ROM, and tried each memory chip by itself. So, I would think it is a problem with the DC jack, fan, motherboard, CPU, or video. Any ideas?

did it work before? what was the reason for the adapter? – Keltari Jan 18 '13 at 21:20
I had this problem and it worked when I replaced the power adapter. – Jakob Weisblat Jan 18 '13 at 21:20
Do you have the same problem if it is not plugged in but running on battery alone? – terdon Jan 18 '13 at 21:45
The new adapter was just something my friend tried. And yes, the behavior is the same when starting off the battery alone. – Steve Jan 18 '13 at 22:11
Might help to be consistent with model number. – pnuts Jan 18 '13 at 23:50

If there is an audible click, then you can be sure that there is a hardware issue. Since you've removed the HD and DVD, this leaves really only the fans or some mains power connector.

I'm afraid that this needs the tender loving care of a trusted engineer. :(
