Excellent guide! I did this to my laptop several times.

I usually find a lot of dust in the inside square corners of the fan housing. Excellent machine with this minor flaw that needs to be addressed every 2 years in my experience.

It runs Lubuntu extremely fast and outperforms i3 and i5 machines with just 2GB Ram and no Windslows...

KH02, are you using Lubuntu on this model? 4920? Did you find all drivers for it to work on Linux?

I dug up my old 4920G a week ago, I just ordered a new processor for it, going from T5550 up to the T9500. I got 4gb ram already, and a 64gb ssd to replace the HD with.
