My laptop keeps overheating and turning itself off. Underneath it gets really hot.
Even playing 3D online poker is impossible, it just overheats. If it is on my lap, I try and balance it so it's sitting just on my legs and has loads of free space under it. This seems to help a bit (it's never turned itself off in this position) but even being on a desk can result in it overheating.
There is a lot of dust, etc that I've cleaned it out (as much as I can easily take apart anyway), but it never used to happen. Any ideas?
The laptop is a Lenovo 3000 N200.
