T42 Booting (POST) problems!!

For past few days, my T42 will not boot 90% of the time.
It doesn't seem to be doing POST at all. I dont hear any beeps.

1) Recently reinstalled windows.
2) Updated BIOS to 3.21 (there is a newer 3.23 available now though)
3) A week after install, T42 is acting up!
As soon as I Power ON, only the Power & Battery lights turn on. CPU fan spins. No other lights show any activity (HDD etc). And the system just stays there ... nothing on the screen.

If I keep pressing the power button (>5sec) and re-trying again and again .... I tried waiting 10sec, removing thinkpad battery, tried to boot from a CD etc stuff... i dont see anything on screen.

But once in 20 or so tries ... it boots without issues!

One more weird thing i noticed on one of the tries was .... when the windows booting screen appears ... the windows logo became faded and the system just froze there! I dunno if this is related to the problem above.

This is 3 yrs old now (no warranty) and is fast becoming a drain on my money now ... replaced CPU Fan, Power adaptor, testing fees etc.

Hope somebody has a solutin to my problems!

If I would have to guess, I'd say that this is your problem given the symptoms:

t42 shuts down when i move it

Short answer: Wedge something between the graphics chip and the keyboard or find a way to reflow the solder on that part.

Agree it doesn't sound good. How recently did you re-install windows? Did the problem start with the re-install?

reinstalled windows just a week back. well, seems like that has started the problem.

Where should I put the paper? Here is my T42 mobo picture ...

Right now ... I am always keeping my laptop on standby after use. I fear shutting it down as it might never restart again!

Ok it seems you have the "long fan" so the GPU is under the right edge of all that copper. Down in the corner there. Right above the mini-pci slot so you can press and hold it down (not too much pressure) and try booting the system. See if it boots no problem. If so then you have the GPU coming loose problem so the pieces of paper would go above that area with the keyboard holding it down.

Oh and someone posted this:

nice lil video on how to re-flow the solder to the gpu socket.
