Question Upgrade CPU on a laptop

[dovyaffe]

I am sure this has been asked somewhere. I have an older Asus K54c that I want to boost up. I switched out the hard drive for an SSD and maxed the RAM out at 12GB (I think that is the max). I have been reading that the processor can be upgraded. My question is, the current chipset is HM65, the processor is an i3-2310M. I would like to upgrade to i7-2720qm. Does anyone here know, or has anyone attempted this succesfully? I read the i7-2720qm and i3-2310M have the same pin layout, but the i3-2310M's TDP is 35w and the i7-2720qm's is 45w. My concern is the heat dissipation. Will the stock heatsink be able to handleit? Before I spend the time and money, I wanted to know if this is worth it. I have watched this

so I know the CPU can be switched out and I have done it on other laptops. But it was always a replacement, not an upgrade. Anyone out there can advise if it would be worth it, or will the throttle to prevent overheating cause a bottleneck to where there is no benefit?

You should stick to 8GB since the chipset will have a hard time coping with any ram higher than what it was supposed to run...and the highest frequency you're going to see your rams go to are DDR3-1333MHz.

HM65, the processor is an i3-2310M. I would like to upgrade to i7-2720qm.
Try and stick to a 35W TDP version of the 2nd generation mobile pedigree i7 processor. You can drop the higher TDP part but the cooling fan might be overworked.

There used to be a forum, notebookreviews, they are now closed but there was a wealth of info about restomodding laptop like your. Apparently I actually have an HP ProBook 4430s which came with an i3-2310M, was looking into doing what you're doing until I decided to play it safe and stick to a 35W TDP of the mobile grade i7's instead of going with the 10W higher chip. Yes I loose out on true quad core but the cooler is what's keeping things cool and the laptop's innards aren't exactly friendly to a hot chip/component.
