I don't know anything specific about that, but my standard process
would be to swap over the RAM in case that's the trouble, then swap
over the CPU (in the case that I have a compatible spare and the
CPU is socketed). If neither of those fix it, then frankly it's
unlikely that any fault on the motherboard will be practical to
diagnose and repair unless it's quite obvious, so I'd admit defeat
at that stage.

The only other thing is that I've had Thinkpads behave very
strangely when their BIOS battery is nearly dead. I'm not sure if
any were ever so bad as to just show a black screen, but if it's
getting some way into POST and then stopping with a meaningless
error or just no obvious reason, then I'd definately try it with a
fresh BIOS battery if the voltage measures a bit low (buy a 2032
cell with solder terminals and solder it to the wires from the old
one to save money).
