sudden power outing

I just had a laptop issue on my Lenovo X61s.
This laptop suddenly powered off while playing a game (StarCraft2), twice within an hour, in the heat of the game (AND I WAS WINNING GRRRR).
lol
Avast doesnt seem to have found anything odd so I can only guess that the fairly recent game makes my old pc work hard even though all settings are on "low quality" (grfx, sounds etc). Could that be a safety procedure to prevent overheating of the cores?

here's about the laptop :
intel core duo L7500 1.60 GHz
2 Gb ram
win xp pro, sp3

cheers

Sounds like thermal protection kicked in to me. The only other thing that comes to mind is your graphics driver. Have you updated to the current version?

 

Yeah i agree, sounds like its overheating and shutting itself down. Try propping up the back and getting some air moved underneath it, that could get it to where you can keep playing when she heats up.
