I am reassembling my powerbook after replacing the display inverter. I want to put the heat sink back on the processor...

Errol, thanks for replying. What kind of thermal pads did you use? I tried to replace them using ones recommended here: How do I replace heat sink with both thermal paste and pads?. But they were too skinny and very difficult to apply. I doubt it will do much good. In doing so, I removed the pads, partially ripping one (and the other has dust on one of the sides). Maybe I could clean the dust off as best as possible and re-stick both on? If anybody knows what kind of pads would offer nice, thick, sticky surfaces and would be easy to apply, please let me know.

I'd also really enjoy hearing the answer to this one. The pads seem about one or two millimeters thick. If I end up just using the pads, would I then have to put thermal paste on the underside of the pad? Are there any issues with small irregularities in the pads' surface smoothness? What if the pads got a little bit of dust on them, probably during dis-assembly of the laptop? Does this present an issue? If so, would it be best to just get replacement pads or use thermal paste? Thank for your answer.
