Hi,
I have an old packar bell laptop (4-5 years old?). I wanted to put a new peocessor into it, it currently has a Celeron M model 350 at 1.3ghz. The spec page on packard bells website says its a 479 pin PPGA socket, but I cant find any celerons that are 479 pin, they're all 478. Could this be a mistake on their site?
 
that's a celeron M, ie, its a mobile processor using either the Banias or the Dothan core.
they're Pentium M's with cut-down cache and less power-saving options.

you'll be VERY hard pressed to find a socket 479 Pentium M, they were never easily available and were always very pricy.
 
I just bought 1gb (2 x 512) off a popular auction site for £20.

If I put a Pentium M 2ghz, 2mb cache, inside the laptop, will this create problems with overheating?
 
Laptop cpu changing is a risky business, especially on older machines. Just because the socket and chipset match that doesnt mean the BIOS will accept it. Some laptops makers used to lock the BIOS to certain families of chips such as celerons to stop people upgrading.

The only way to see is to search the net for people who have sucessfully done what you intend or to try it yourself.

What about over-clocking, is this an option for a laptop?

no the bios on a laptop is hardly configuable at all other than boot device, to be fair you'd be better off selling it and buying a laptop with a newer processor such as a core 2, your not gonna see much difference from an upgraded cpu as the platform is quite old.
