Since upgrading to 11.10 from 11.04 my laptop rapidly heats up and eventually turns off by itself (due to the intense heat I presume). This was not happening whilst running 11.04; I opted then to run gnome rather then unity, not sure if this makes a differences. Was hoping to solve this problem as it worries me that this continues to happen.

if anyone can help me, or i need to provide more information on my system please provide step by step instructions on how to do this as I am still a beginner to the linux platform.
