Question Sony Vaio VPCF136FM CPU replacement

Sep 21, 2021
I have read people saying you can't upgrade laptop hardware and that isn't entirely correct. On my Dell Inspiron 1525, I've replaced the CPU several times. A couple of other Asus laptops I've upgraded CPUs as well. All worked better than the original equipment.

Every time I try a different system, the learning process starts for that chipset which is where I am now. I know what the documentation says and I use that to choose a processor. My question is to those more experienced than myself.

I want to ask you if this is realistic to do (your experience) as opposed to theoretically possible (the documentation I follow).

Laptop: Sony Vaio VPCF136FM
Laptop Chipset: Intel PM55 chipset

Original CPU: Intel Core i7-740QM

Replacement CPU: Intel Core i7-2860QM

The replacement is to provide faster processing and less thermal issues (I suspect damage). If this can be attained with an alternate choice in CPU, please suggest away!
