It'll grow back, right?
Hmm. I need to remove this, very firmly attached, processor from the heatsink and fan assembly.

I’m sure if I just apply a little pressure2…

Bugger.
In an effort to take something positive from the experience, I’ve created a photoset on flickr that describes the re-assembly process of the Sony Vaio K315B.
1 More like a combination of pressure (on the processor, not me), lessening patience and a knife (resulting in two cut fingers.) Ho hum.
