Thanks to your handy manual, I had a reasonably easy time replacing the Combo Drive in my brother's friend's PB (1GHz 12" Aluminum DVI).
Until, that is, I tried to reinstall the heat sink.
No matter how much or little pressure or torque I applied, I couldn't get the 7.5mm screws with springs to tighten or even catch. I gave up and decided to post here only after one of the screws, propelled by its spring, shot across the shop, probably never to be found again. And you don't seem to sell them.
In fact, looking at the remaining "screw" closely, I can't figure out how it could possibly work. It doesn't even appear to be threaded. It doesn't work if I try to screw it directly into the inserts in the logic board. I'm not even sure the inserts in the logic board are threaded. The screw doesn't seem to be like the Southco 5T heat sink screws I've dealt with in the past. Yikes!
Any advice would be greatly appreciated.
Also, assuming I'm not screwed and the screw problem can be solved, shouldn't I either replace the thermal pad for the processor or possibly add some thermal grease?
