What damage shall I ask him to look for? I can ask for a favor at work
(we have a department which develops logic boards for particle
accelerators and their detectors), but I'm a little lost about what
signs of damage should they look for, and I prefer to do my homework
first before asking a specialist with a limited time. If there was some
CMOS device damaged by the induced current, how would the technician tell=

That sounds interesting. Is there a list of T61 mainboards which are
known to fit the T60 chassis? The expanded memory support would be
handy, as well as the 64bits. (My CPU already handles virtualization
well, though.)

Anyway, given the proximity of the BT adapter and the LVDS cable, I'm
going to re-seat the connectors as a first step. I'm gonna do that
tomorrow at a properly equipped place.

Thanks,
Jan
