Worked in Canadian Embassy in Ukraine, Kyiv. HDD maybe consist interesting info ;) Didn't turn for many years,was in working order when last turned on. I didn't try power it on, because afraid damage internals. I took it completely apart to show the insides. See small repairing traces on power connector of motherboard, bios battery failed and slightly damaged neighboring microcircuit (but it looks like ok, legs remained or can be easy restored) and suspicious marks at two solid capacitors (which is very strange, they less susceptible to damage over time, maybe its repairing traces). More pictures you can see there, because of limit of pictures: (copy & paste in browser's adress bar)
