the dell cpu is probably a mobile chip or a northwood dye cpu. your desktop being a 2.5ghz sounds like a prescott dye cpu which the dell board is unlikely able to run as in not post. this is from the user guide of your laptop.

Considering that the dell has a mobile processor, it probably can't. Changing the CPU of laptops is a very tricky process, sometimes the CPUs are soldered on!

abuzar, it might or might not have a mobile cpu on it. dealt very much that the cpu is soldered on a laptop motherboard.

I read somewhere that they do. Oh well, the point is the chances are slim.

well it is a removeable CPU just thought id ask thanks. It is my only stable comp as it is now so i won't risk it LOL. And something else i thought about i have a new AMD 2x socket AM2 64 bit (of course) and was wondering if i need a new version of win xp pro sp2, like something to utilize the dual core or will my version do it anyway. I have currently installed win xp pro SP2 V-5.1.2600 . So again thanx for anything anybody can think of

And it is a mobile CPU it looks like an old AMD 1.8 or something and my desktop Cpu is much fatter but looked like it might work (looks like my dual core)

So do you think it would create more heat if i put it in and it worked ? remember its a laptop too and the fan's are quite small they keep this one the 2.0 Ghz at a nice 30 to 37 degree's , but my fan's are running at full speed all the time keeping them on low keeps it at about 45 give or take a degree

you can try it but doubt it will work as the laptop bios probably won't recognize a prescott cpu & won't post.
