Changing ThinkPad 380Z Processor for 390X Processor

[TexRodeo]

I have a ThinkPad 390X that is basically a parts system and I have a ThinkPad 380Z that I use. Would it be a possibility to swap processors from the ThinkPad 390X (400Mhz) to the ThinkPad 380Z (300Mhz)? Both systems are Pentium-II systems. If this could be done could I get detailed information as to how to do this? I am a PC Tech but really dont know a great deal about these thinkpads. Please advise me further.

Thanks in Advance,

Larry

I don't know the particulars of what you are attempting, but take a look at the following (2) Hardware Maintenance Manuals. Check the part numbers of the CPU cards to see if they appear interchangable.

Hardware Maintenance Manual (November 1999) - ThinkPad 390X

Hardware Maintenance Manual (August 1998) - ThinkPad 380Z

That aint Helping what I Need. Any Other Ideas?

the 390x uses mmc2 form factor,the 380z uses the mmc1 form factor,you cannot interchange the cpus
what you need is a mmc1 333-400max cpu to upgrade the 380z
i tried a celeron mmc1 400 cpu on a tp600 sure enough it posted
however ibm programed some kind of block not allowing the processor to procceed,(schemers!)
didn't stop me when i swapped the cel400 for a p111366 mmc1 though. that booted straight into xp indeed.
infact i sold that laptop fitted with a internal dvd/cdrw,to a friend that was on the verge of ordering a new lenovo,i explained why they are better off with the proven rather than the flimsy,the hundreds they saved and the fact they went for a recycled machine,aiding global warming,add to that no brainer windows reloads(no drivers needed)in 2k,me,xp,2k3 you can see why that solution
contributed to the no regret factor.
the 380z is a top machine with the 128 dell edo ram bringing it to 160 mb.96mb is good for win 98,2k + me(if one can't find the 128mb stick).you can also fit a combo drive in its bay and it will detect it and work beaut,(as long as combo firmware is comparable).same drive swap rule applies to every single thinkpad post 1998).
