CPU Upgrade on Late 2010 MBA Possible??

It cannot be done. The CPU is soldered on the logicboard. To upgrade it you'd need professional skills and an expensive soldering station.

 

I love a blatant contradiction!

 

Yep. It cannot be done by the OP. But a professional, it can. I know of one person that has upgraded the CPU in their Macbook and it was done using a very expensive soldering rig.

 

Keep in mind that even if you have such capabilities, an ungraded processor would also have to be supported by the firmware, which is highly unlikely.

 

I don't agree with that, I reckon given the natural choice would be a 1.6 C2D upgrade then it probably would work.

But it's the same as the argument for upgrading RAM, it is possible with the right kit, and people have done it, and i'm sure those same people are the ones who'll also upgrade their CPU too. But if you don't have the right kit and relevant experience or access to somebody who has then don't bother trying unless you're prepared to feck it up.
