I think thinkpads of that generation had RF shielding issues. I had a W520 that would crash whenever it was moved across a table or removed from a backpack. Turns out the shielding on the RAM door was faulty and the static charge generated by friction on the bottom of the case was enough to corrupt the ram contents and crash the laptop. Talk about a bizarre failure.
