I have a HP Pavilion Laptop, Version DV5000 running on Windows XP SP2
The issue has continued for a few weeks now, quite randomly. Often times I will simply click the mouse of touch a key on the keyboard, and the computer will turn off. I just wiped my entire hard-drive and reinstalled Windows XP SP2, and the computer has been working better, but I occasionally still get the random turn off. Along with clicking and typing, and sort of jostling or movement of the computer also turns it off. The only way to turn it back on, is by unplugging the AC adapter, replugging it back in, and turning on the power button. I also find that I get less shutdowns when my battery is removed from my system. The fan is on and working, and I've been checking my core and HD heat levels, and they stay around 35-42 degrees celcius.
