In theory - anyone with PPGA988 socket. I replaced my i5-3210m for four-core i7-3632QM. But you need to look at TDP (so as not to go beyond 35W, like a native processor). But if the cooling system "with a margin" - for example, if this laptop exists in version with i7-Qm - most likely the cooling system is designed for them, for I doubt that different from the same laptop is different. Then you can and four-core I7-2630QM. If the CO, let's say, is calculated only on 35W (like A 5) - you can try four-core i7 to put - the temperature in the work will be higher, but not the fact that it will be "beyond" if it has been "with a stock". The maximum that is from 35W from the second generation - i7-2640m, which does not particularly exceed your ay5. + 500-600 MHz, 1MB L3 and 100 MHz to HD 3000.
P.S. It was easier for me - ay5third generation
has 35W TDP, then there is also an i7-QM with 35W. The second generation has all four cores - "still" 45W. Post has been editedAstraVE - 11.06.13, 16:19
