Upgrade laptop cpu i3 to i7

I recently got a Packard Bell laptop as a gift and it comes with an i3 2310M, 4ghz Ram, 500gb Hard disk and a Nvidia 540M gpu. I'm very pleased with it as I can play all latest games and do several things at the same time e.g. working with a huge Java applet, listening to music, browsing the web with more than 30 tabs opened on Firefox etc. However, I want to upgrade its cpu and get an i7 and more precisely the 2670QM.

All Packard Bell Easynote TS 11HR series, no matter if they have an i3, i5 or i7 cpu, have the same bios (I have flashed mine to the latest version), and also have the same motherboard, the SJV50_HR. So here comes the hard or easy part... Will I be able to upgrade the cpu easily or are there any compatibility problems that I'm not aware of?

For instance, I'm aware of the different TDP statuses between the i3 (max TDP 35W) I currently have and the i7 (max TDP 45W) but we're talking for a mere 10 points more when it comes to i7, which I believe my laptop can handle and I'm willing to risk that. However, I'm not sure if my system is compatible with the i7 cpu when it comes to sockets and chipsets. My system has the HM65 chipset and the 988 B rPGA socket (also know as G2) and after conducting a little research on the web, some sources say that the 2670QM is for 988 A rPGA sockets (also known as G1) only and not compatible with the G2 while some others say that it is compatible with both sockets.

If that helps, according to Intel's website my current cpu has the following "package size": 37.5mm x 37.5mm *rPGA988B) AND/OR 31mm x 24mm (BGA1023), while the i7 2670's is 37.5mm x 37.5 (rPGA998).

I'm so confused... Can someone please enlighten me? Thanks in advance and please excuse my English.

 

It seems like you've done your homework, but I still question why you 'need' it.

For your use, upgrading to 8GB RAM will be more beneficial than upgrading the cpu simply because you 'want to'.

Also, don't disregard that 10W difference - while the BIOS, MB and (maybe) the socket support the i7 - that doesn't mean the chassis and/or the heatsinks/fans will.

Better to buy the same system (assuming you're 100% satisfied with it, of course) with an i7 from PB and sell yours to cover some of the cost. That way, you won't void any warranty, and you will get a system that is built for the higher heat tolerances of an i7 from top to bottom.

Good luck.

 

you want the rpga socket, since the bga is for soldered cpus

if your model supports quad core i7, do check if there is any difference regarding the cooling, since in the mobo there isnt.

 

This is very important, i7s have a higher thermal output then the i3s and if the cooling is barely adequate for the i3, you could end up frying something with an i7.

what are the max temps you're getting with the i3 at 100% usage.
