No ideas?

Re: mother board for lenovo T400 turn on normal but....

Hi Karim, did you check the caps C313, C310 and C307 to ensure they're not shorted to GND?

Dear all,
I have a T400 that turns on, briefly displays the boot up screen and suddenly shuts off without beeping. I've checked during the time that's on and, as far as I can see, all voltages (including VCCCPUCORE) are present.
Quite strangely, if I press on the VGA chip while it's booting, the screen keeps turn on longer but never completes/passes POST nor it shows nothing different.
At this point I'm inclined to think that there's an issue with the BIOS chip or the VGA one, but I'm not sure how to diagnose them.
What will you suggest?
