Ibm Thinkpad T23 Boot Problem

I got T23 for a repair today, was BSOD with boot problems with winxp, so first thing, I searched, how to get a HDD out, got it, then understood, I have no such cables around, so I inserted it back, to format it, BUT bummer! It does not turn on anymore, I mean, fan, battery lights and power-on lights ar lit, but nothing happens, just blank screen, no post signals, nothing.
I opened it, took all dust away, poked the mobo, everything was firmly attached and clean, nothing!
For now, If I can't solve it, it looks like I am in fault of non-working laptop, that is realy bad. I need some solution, what to do! I have tried deattaching all plug-in cards, every memory, no change... PLEASE HELP!

picked up a T23 at a flea market today for $5.00 USD. Had the fan up and down issue. Found this site and tore it apart just to find the magnetic looking thing ready to fall off. Soldered it back on and it's working great!

Thanks everyone!

Amazing! My T23 was dead in this way yesterday. Today I found this thread and I fixed it!

Thanks a lot.

Thanks very much for this thread, my old t23 which I still use would not start and all I could hear was a wearing sound coming from the fan. I have done what everyone else has done taken out the mother board found that the little magnet thing had come unstuck on 1 side as soon as I touched it, it fell off in my hand, so after reattaching it. Its all fixed and works as good as new.

Thanks all.......

where can I find this part to be soldered back on the mobo? Can you post some photos.

Thanks.

PS.when I press the keyboard on the "Q" key or around - it goes on!!! there must be some part loose. I will try to find it out, but any help will do.thanks.
