my computer occasionally randomly shutdown down. It happens especially while watching video on youtube or just a video through vlc.
It nmever did this before and even does it on windows ( I dual boot windows and 11.04)
The only clue I have is that, suddenly, the fan will start spinning really hard, becoming quite audible for 4 seconds and then it's off. I see this in the kernel logs

I just checked on windows and confirmed that it does indeed happen on windows as well. It shuts down with the same sudden whirring up of fans. This may actually be a hardware problem. Would not be surprising since I spilled a whole glass of coffee on this laptop once, though quite long ago, and the keyboard has been sporadically working since then and just isn't responding correctly now.
I hadn't mentioned this before to see if I could get a response more enlightening than "it was the coffee"

I'd suspect it is overheating and automatically shutting down to protect itself from damage.

If you are nifty with the screwdrivers and have the patience of a saint you can disassemble the laptop and clean everything up inside with electrical contact cleaner. Pay particular attention to where the ribbon from the keyboard connects to the main board, as well as giving the mechanics of the keyboard a good blast with cleaner to try to remove any residual coffee gunk. Whilst in there it would be worthwhile removing, cleaning and reseating the cpu heatsink with a little blob of fresh thermal paste.

It's not difficult to do, just really fiddly with lots of tiny clips that like to break when you so much as look at them. Take your time and don't force anything - if it seems to require force you've probably missed a clip or hidden screw somewhere.

Good luck :D
