I have the same trouble, and I have read a lot about people heating up thier motherboards and reflowing the solder. Many people say that it works. Has anybody else heard of this?
Why doesn't Lenovo replace these boards if they can't handle the stress of regular laptop use?

Stress of regular use should not include carrying an open laptop with one hand, and that's what killed most of the T4x/R5x machines affected by this syndrome...
Lenovo was replacing motherboards (and still does) for all the units under warranty, which was standard three years for most of the T4x models. IBM also changed the soldering technique and materials on late T42/p units and carried it into the T43/p series which almost never suffer from this problem. This issue was addressed entirely on T60 machines because they don't suffer from this problem whatsoever.
Hope this helps.

I have a similar problem. My T42 goes into sleep mode right away when it is turned on. No option to boot into BIOS or any other help menu.
I took out the battery and booted with the power cord only and it works. I know the battery is fully charged.
Thank you for your help.
