Change CPU in my laptop

[John Mar]

Hi,i have a Dell inspiron 15R(N5110) with an Intel i3 2310M and i want to replace it with an i7. My motherboard is the Dell 0FXK2Y and i found that the compatible i7 cpus with my socket and my chipset (HM67) are plenty, such us i7 2630QM, i7 2720QM, i7 2760QM which i have found in a good price.
My cpu isn't soldered to the motherboard and I would like to tell me if I have a problem any possible problem such us with the higher TDP .
Thanks

personally I would not recommend replacing your cpu and save up for a better laptop as its a great mess to replace the cpu. The amount of hardware that stands in between you and the cpu is immense. The performance difference is no that great anyways. If you really want to replace it, the TDP is not an issue at all. Good luck!

You believe that won't have big different ,because i rely on benchmarks only and i saw a difference between them.
I have found about 70$ the models that I said in my post and i think is a good choise.

Higher TDP could be a problem. Because laptop components fit together so tightly, cooling & heat issues are a big consideration, as just a little bit of extra heat will either start throttling performance, or worse start damaging components.

Now, I've been having some trouble tracking down information on this particular board, most likely because a) it's a proprietary OEM board (& it's notoriously difficult to track down that information), & b) because of the age of the system itself. Now, that being said, I did find a post on the Dell message forums where someone posted a screenshot from HWInfo showing their Dell (Inspiron 15R N5110) using an i7-2630QM CPU (http://en.community.dell.com/support-forums/laptop/f/3518/t/19460224?pi239031352=2), so you could probably go up to a 45W TDP chip with few (if any) issues. If that's the case, though, then I would also consider seeing if you can get an Ivy Bridge chip instead: newer architecture than your Sandy Bridge, so it would have a little more performance. They have quad-core 45W versions, like the i7-3610QM, 3630QM, 3740QM, or even up to the 3840QM.
