Upgrading Celeron to P3?

[govtcheez75]

I know that many older Mobile Celerons, and Mobile P3's use the same socket, so is this possible? I'm looking to upgrade this laptop:

...what I have are 2 P3 processors (700mhz, and 750mhz) from other laptops (compaq, and acer) that I would like to put in there. Anyone know it they are compatible?

check the pins, cuz the P3's had a whole lot of different pin packages. Also check on the thermal output of the P3 vs the celeron to see if it would overheat

Isn't that particular LifeBook model sold by Fujitsu, not Toshiba?

I believe the CPU is integrated with the motheboard on that one. I don't think you can upgrade it.

A lot of processors in those days were on removable processor modules. Do a search on ebay- you might be able to find something that works.
