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

Just in case, let me correct one point.

I checked the sSpec name again. I think Intel's search engine is
something wrong and does not hit SL53S. Therefore my previous
post was somewhat confusing.

My point is, SL53S=SL58S=SL5TF.
These are all P3-1GHz coppermine micro-PGA2 CPU.which
work fine with T20. FYI, SL53S is the one most readily available
on the market among these three, and running in my T20.
