Socket 479 compatible even on laptops?

[Ninja48]

So I have a laptop that's about 5-6 years old. Specifically it is a Toshiba Satellite L25-S1216 It's running terribly. Task manager tells me the CPU usage seems to be shooting up to 99% whenever the tiniest of things are done (ex. moving a window around, playing music). It has been reformatted and it still acts like this, even though there is literally nothing else running (acts the same in safe mode). I figure I'll replace the CPU and the hard drive. The CPU specifically is a socket 479... If I find a socket 479 CPU to buy, is it guaranteed to work on any motherboard (laptop or desktop or whatever) that has the same socket? Does anything else factor into the working-compatibility of a CPU in a motherboard?

Most mobile cpu's are soldered to the socket and can't be replaced, but some are removable. You need to check this before buying anything.

There existed three electrically incompatible, but physically identical, versions of this socket

Laptop CPU's are different from a desktop's. We would have to know exactly what it is. Even though it is the same socket, your motherboard may not be compatible with it.

But, I would not waste your money on fixing this. Save your bucks and buy a new laptop/desktop
