I ordered my M90 on Dell Outlet a while ago. Top of the line everything except the CPU. It's a T2300, I believe (Core Duo, 1.6 Ghz). In preparation for Windows 7, I want to upgrade the CPU for speed and for 64 bits.

I'm looking at a T7200 (2.0 Ghz, 667 fsb) for under $100 new, but pulled. First off, just to double check, this will work in my laptop, right?

Second, how involved is replacing the CPU? I've built desktops before no problem, and I've repaired my wife's screen on her HP, but never took this much apart on a laptop. I assume it won't be too bad as long as I follow the manual and keep track of parts.

Third, my warranty only has 90 days or so left on it (complete care). Do you guys see it as that big of a deal? It's been a workhorse from day one and I baby it so I'm not too worried.

Lastly, what kind of thermal pad/paste should I use on it? I assume it has a pad. Will I need to replace it, or will the existing pad work? Can I use paste on it if I wish? What have you guys had success with?

Thanks for the help, everyone.
