upgrading a pentium m

[nonnus]

hi there,

is it possible to upgrade a pentium m (a banias to a dothan, for example, as i believe they have the same socket/chipset) ?

also would it be done just by swapping cpus in the socket or does it require any "advanced and dangerous" techniques ?

thanks in advance

Can you open your laptop to get to CPU? If you can, see how it is welded to the mobo, if you can undo-redo it, well, then keep the flag in your hands.

..this is very useful and helpful place for information...

I stand to correction, but I am quite certain that the Pentium-M (above 1.4GHz) is just a plain old ZIF socket. It depends on the bios (and thus make of notebook) whether or not you can upgrade to a dothan from a banias.

don't kno where u get the welding from - was that supposed to be a joke?

Forgive me my incompetence, I meant soldered not welded if that matters, and it is not a joke (if that matters as well😉

PS: "Generally (but not always) the CPU is soldered onto the mobo in laptops. Cuts down on not only problems with it coming out after moving around but also people <b>voiding</b> their warranty just to <b>change</b> the processor."

Generally, yes, with a lot of processors, this is true. However, this does not happen with the Pentium-M's, except perhaps with the low power ones. I think they mainly stopped doing this with the Pentium II (& celeron) notebooks, and it has now all but tapered off completely. If you get a P4 or a PM notebook today, i can all but guarantee you it won't be soldered on.

'Incompetence' - or rather slight "miswording" forgiven.

hi all,

and thanx for bothering,

i had the same impression,
that these actual pentium-m are removable thru a zif socket

the system i was intending to try it will always be an intel 855pm as it supports both cpu´s

i was wondering about getting an asus (w1, m6) or a vaio a195 with a 1.5 banias (or even lower...) and chuck it with a 745 dothan

what do u think people ?

thnaks a lot

I don't see why not... I suppose u could give it a try - it will most likely work.

hello all,

and thank you for trying to help

i just had the chance to dug into as asus w1n yesterday
after his owner though it had died on him just 2 weeks after he bought it,
it didn´t of course,
the poor bastard just never got to plug in the power supply so the battery just went naturally dead....

i had realised that in the beggining of course but i just had to get inside it.....😉

anyway with very little fuss, about 20 regular philips screws after and absolutely no warranty voiding seals,
i was able to contemplate a very beautifull SOCKET holding the cpu (in this case a 745, so no need to upgrade it in the next few months...), i just didn´t take the chance to take it out and stuff some artic silver on it because one of the (again regular philips type) 4 screws holding it finally had the little warranty sticker....

so at least in this model it is quite easy to upgrade the cpu,
i even thought about documenting and ilustrating the procedure to get to the cpu

i would like to keep this thread open to allow for more people who get inside different laptops and their conclusions about cpu install/upgradabillity

Like I said, all Pentium-M's are socket based - the only ones that they might have to integrated and thus solder on, are the LV models. Anyway, nicely done getting into that ntbk - and omg, that poor notebooks owner is... words fail me.
