so can i simply put a 'centrino' mobile processor into a laptop which is currently running a northwood celeron which has a chipset that is part of the centrino family (intel 855GM/E)?

I know that the chips FSB (400MHz) is supported by my m/b and so is the socket (478).

so.... what about voltages? What controls the voltage that is put to the processor? because the current celeron will most probably have a different voltage to to pentium m i want to throw in there - so will this be safe?

BTW the motherboard is an ACER Travelmate 240 with i855GM/E chipset.

NOPE Centreno and northwood are differnt chips. You might be able to put a northwood chip into the laptop. But it best to keep what u have in it.

Northwood has 478 socket. Centrino (= Pentium M & Intel Chipset & Wireless) has a 479 socket. There is however an adaptor by asus with witch you an run a pentium M on a 478 Mobo

you would have to physically open the laptop and remove the cpu hsf package and see what socket you have, aswell as check with the manafacturer what cpus are supported

laptops are a pain in the ass for upgrades

i know what socket it is, i've taken this whole machine apart before. so i guess the answer will be to contact the manufacturer

{hang why didn't i just use CPU-Z???}

ah gotcha, cause some lappys have the cpu soldiered to the board (BGA), perhaps google your lappy and see what others have done, do some research to what you can do.
