Intel M processor upgrade

[Mradzz]

im thinking of upgrading my laptop cpu to one of the newer generations. im curious whether i can install a intel 4300m processor in its place?

or if not what would be the latest cpu i can upgrade to from a 2450m?

any input is appreciated

You can't change the CPU in a laptop.

That is not true as I have done it plenty of times in older ibm thinkpads. (T43) Depends on the laptop...

Correction, you can't change the CPU in most laptops. A majority of them are soldered to the motherboard, and for those that aren't, you need to find a CPU with the same TDP and socket, which is usually nothing. However, I swapped out the Pentium B830 (Sandy Bridge) in one of my laptops for an Ivy Bridge Pentium B2020M. The improvement was marginal, but the replacement was $5.

Thanks for pointing out on the socket and tdp. just wondering if you would know whether any bios related issues could arise. even though the cpu socket and tdp are the same.

Yeah, there are those too. My laptop shares a socket and TDP with some Ivy Bridge i3's, but the chipset has artificially blocked using "Core" processors, so if I were to install one, the laptop would shut off exactly 30 minutes after booting. In other cases, the microcode for the CPU you're trying to put in might not be there, and it either might not boot (CPU unrecognized) or might boot but would not work correctly (e.g. show as "unknown CPU, missing AVX extensions).

Upgrading laptops is really hit or miss.
