T42: Upgrading 1.7 735 To 2.0 755...

AFAIK, the swap involves unscrewing the bottom away from the top, removing keyboard, removing OEM CPU, thermal compounding new CPU in, and replacing keybaord and housing. Anything I may have missed? Comments, recommendations, suggestions before I start?

question: is it really worth the trouble? IMHO, a 7200rpm hard drive will offer a MUCH more noticeable improvement in speed (and won't void your warranty in the process). of course, I'm assuming you've already upgraded the RAM to at least 1 gig, etc.

Indeed I have. Next option is to swap out the CPU. Looking for tips and hints...Suggestions?

I have gone in there before, and it's really a piece of cake swapping the CPU. I went from a 735 to a 755 as well, and strangely enough though, the laptop feels peppier on the lowest clock settings and just gets hotter than before on the highest clock settings. For me it was a win-win situation upgrading the cpu, it was a good learning experience and it only cost me 50 dollars to upgrade to a secondhand 755. But either way though, good luck to ya and hope you learn something from the experience.

The best thermal compound for CPU's is Arctic Silver 5. I use it on all of my desktops. You wouldn't think different thermal compounds make much of a difference, but they do. Arctic Silver makes the thermal paste.
