Pentium M 1.7 for Mobile Celeron 2.4

An odd one, maybe, but my Toshiba Satellite (A15-S129) has a mobile Celeron 2.4GHz CPU and an Intel 852GM chipset and I'm wondering if the 1.7GHz Pentium M from my old T42 will work in this computer?

Anyone??? Bueller???

hmm probably not. The Celeron probably uses the Pentium 4M connections while the Pentium M has a whole new one. Just like you can't take a R series or a T30 with a P4-M and slap in a PM

Exactly. It won't for sure.

I bought a T40 for parts a while back that was as dead as a doornail, no lights, no nothin'. While I was stripping it for the good parts, I discovered it had a P4-M 2.0 in it. I put a good PM 1.5 in the socket and it fired right up.

So...while a P4-M may fit in the socket, it won't operate that way.

T4x series NEVER came with a P4-M chip, the T30 was the last in the T range to use the P4-M. The R4x series had some too and some Celeron-M chips. All of the T4x series were Pentium-M. They were introduced with the new Centrino campaign and therefore they all used Pentium-M chips. Can't be Centrino without a Pentium-M chip.

Actually, that was my point - someone put a P4-M in the T40 I bought and with that chip in it, it was dead. A P4-M will physically fit in a PM socket but it won't function.

The T30 was also the only T-series machine to have a Pentium 4-M.

Thanks Smidgley. While the two processors appear to be pin compatible, they are clearly not electronically compatible!

Oh well, wishful thinking!
