Re: [Thinkpad] Upgrade T-20 Thinkpad P-III 2647-81U Laptop CPU

Hi, Mike.

Quite a few people on this ML, including myself, have upgraded the CPU
of our T20 to P3-1GHz. The common trouble in this upgrade path is the
overheat problem. I suggest you check the CPU temp after replacing the
CPU and if you find it too high, you should also replace the fan assy
to the one designed for T21.

Take a look at some stories regarding T20 CPU upgrade path found in
these threads.

Good luck.
