Can you replace a Laptop CPU?

Vitric9 · Feb 20, 2014

I know some Laptops have their CPU's soldered in but and some are not. I forget which is one is BGA or PGA and I will often find sites that say the same CPU is either or. I am trying to pick out a decent laptop and If need be I would like to replace components in it. I would like a laptop with an Ivybridge or haswell i7.

If you pick one up with a quad core i7, you wouldn't need to upgrade the CPU. By the time the CPU isn't enough, you will be on a new gen of chips anyway.

I am not sure about current laptops. I would think potentially a traditional sized laptop could have a replaceable CPU, however, anything in a slim form factor is most likely soldered to the board. To be honest, I don't see the reason you would want or care about this. If you are looking for an upgrade path you will want to move onto a better performing architecture anyway and would not work with the existing chipset or socket. If you are looking in the case there is a failure, I personally have never had a laptop or PC CPU failure that was not DOA or faulty in some aspect from factory. CPU's typically fail right out of the gate.

Just my input. Purchase a laptop with the CPU that best fits your needs. Unlike a PC where you can replace the mobo/cpu you can not in a laptop so you would need to replace it.

PGA based CPUs can indeed be swapped out, but you have to be careful when doing so. The laptop's firmware needs to have support for the new CPU, and since most laptop firmware is OEM it's occasionally a luck of the draw. Furthermore, the laptop's thermal design needs to be able to handle the new CPU as well.

Thanks I was not sure as I was looking at some specs from the i7 3740qm and the i7 2860qm and often I saw PGA on on thread and BGA on another. I though it was PGA. and I was only Curious Bceause I have a Broken Laptop with a G2 socket i think.

Most of Intel's mobile microprocessors are available in both FCBGA and FCPGA formfactors. This gives OEMs some selection to work with.
