Computer powers off while performing aircrack-ng

[davidhebert]

I was learning the wpa cracking method using airmon and aircrack with word list. I get to the part where its running through the list and after about 50min to 1hr the laptop just shuts off. No shutdown screen or nothing. It has done this three times. Any feedback on this would be great.
Laptop is an 08 hp business laptop with a core duo.
- Backtrack version (KDE 5r3)
- Backtrack installation (HDD)
- Last typed command aircrack-ng -w /root/Desktop/darkc0de.lst test1-01.ivs

Thanks i advance for any insight

Is the laptop overheating?
Is it running from a battery?

What are you "power" options (Screensaver? Sleep enabled?)

same happens to me.. when i am performing aircrack the cpu usage is 100%. After 3 minutes it shows a screen saying that the computer is shutting down.. so i think that this is some kind of security tool, i don't know.

Is there any way to turn this "tool" off? so the only way that the computer can shut down is suddenly, when the cpu can work anymore?

Sorry for my bad english

Im still new to linux but i believe i have hibernation turned off. The laptop is running on ac power.
I just tried the backtrack live cd on my macbook pro and it heated up to about 170 f so i have a feeling that both computers are getting too hot.
how can i get backtrack to detect temp and fan controls?
