I have an IBM X31 notebook that is running windows 7 home premium. Its current specs are a 1.4GHz intel pentium processor with 1GB of RAM. Is it possible to upgrade the processor in it and if so how and which processr(s) would work with it? Thanx in advance =)

I have a 1.4Ghz X31 and I am on my sixth ThinkPad now (a X200s). I've taken ThinkPads apart, upgraded them, fixed them, etc., so I can tell you that you definitely cannot upgrade the processor on your X31 - it's soldered to the motherboard.

I also do not think that Windows 7 well run very well on it and XP will work a lot better. Your X31 will have a XP Professional licence as standard.

You can upgrade the RAM to 2 x 1GB though, which would help a lot. You can possibly upgrade the motherboard to one from a X32, which came with the Pentium M Dothan up to 2.0Ghz (the X31 came with Banias chips up to 1.7Ghz, with half the amount of cache).

I actually have 2 x 1GB RAM for the X31 for sale. I will also be interested in buying your X31 motherboard if you upgrade it. –  paradroid Oct 30 '10 at 13:42
how much would u charge for the RAM? and how would i go about upgrading the motherboard? i havent actually opened it up, is it simply taking the old one out and putting the new one in as well as changing a few wires about? –  Sammy Oct 31 '10 at 16:32
and of course i would be more than happy to sell u the motherboard, i have no use for it! –  Sammy Oct 31 '10 at 16:33
also, sorry about this, is this the right motherboard IBM X32 39T0404 laptop motherboard? alibaba.com/product-gs/280028310/… –  Sammy Oct 31 '10 at 16:34
@Sammy: Yes, that is an X32 motherboard, but it does not say which CPU it comes with, so you'll have to look up the part numbers. You will also have to double check if it will physically fit, as I know that the X30 and X31 motherboards are no interchangeable, even though the chassis is very similar. I can ask on 'the unofficial ThinkPad forums'. My email address is on my profle page if you need any more information or parts. –  paradroid Oct 31 '10 at 17:35

Running Windows 7 Professional on X31 with 1300MHz Banias CPU. I can tell you it runs well even with only 1GB RAM. Takes 3 seconds to open MS Excel 2010.

I also installed Intel 2200BG miniPCI wireless card. You need to tweak the laptop to accept the wireless card (utility available in the net). Otherwise you'll have to shell out $$$ for an IBM approved wireless card.
