overheating

I have a Dell Studio 15 and I am running Ubuntu 10.10.

When I close my lid or select the suspend option, the machine suspends as indicated by the slowly pulsing power indicator.

I'll put the machine in my bag and after a while it seems that the machine resumes, at least I think. When ever I go to get it, it's overheated and the system cannot resume. I am guessing that the processor resets in this overheat condition, but heat is still generated. This has happened about three times and I'm getting worried that I'll end up damaging the machine.

How can I diagnose why the system is resuming from suspend? Can I force it to never resume from suspend if the lid is down?

What could cause such a behaviour? I'm running 32-bit Ubuntu 12.04 with the 3.2.0-25 kernel on a HP dv5-1178er… >>> More
