I want to upgrade the CPU of my T430s laptop from i7-3520M to i7-3632QM.
I'm sure i7-3632QM is supported (same socket (BGA1224), same TDP (35W) and microcode found in BIOS (306A9.PAT)).
So my question is:
1) is it possible to de-solder the current CPU without damaging it, and to solder the new CPU without damaging it and the motherboard ?
2) if so, what tools are necessary? who can do that at a reasonnable cost?
Until now, I was unable to find anyone able (or willing) to do that (I'm located in France, and I have tried a local fablab, electronics shops, TV repair shops, ...). Any hint would be appreciated.
