the title says almost everything.

If i suspend my ubuntu 12.04 on a compaq 615 laptop, on wake up everthing works perfectly apart from the fact that the fans don't wake up, cpu heats and upon reaching 90°C somehow triggers the fans to start. (idles at around 59°C).

Any ideas?

This sounds like a hardware issue. Try a live boot and see if the same thing occurs. If it does, you might want to consider taking the computer to get repaired. – Switchkick May 16 '12 at 13:26

Check for a bios update – psusi May 16 '12 at 15:02

The problem might be with your laptop because I have seen many cases where it becomes difficult to gain back your session after 'suspending' from terminal. Try cleaning your fans for one thing.

They are crystal clean and work perfectly when booting+shutting down. – sdrubish May 16 '12 at 15:24
