Beneath the heatsink we find...BRAAAAINS! Or in this case the CPU.

Microsoft equipped this iteration with a 4th generation Intel Core i3, i5, or i7 processor depending on the model.

Our model features a dual-core, 1.9 GHz Core i5-4300U with Intel HD Graphics 4400.

Tech zombies that we are, we'll have to be content to leave this CPU in place, as it is not coming off the board.

Millions of upgrade junkies suddenly cried out in terror, and were suddenly silenced.
