I posted to this thread back in March and I just thought I'd update my situation and make an observation. My shutdown problem went away as soon as I got rid of my generic AC adapter and went back to an HP OEM AC adapter. I had never had this problem until I started using the generic adapter. I don't think that means that temperature is not a factor. Since many of you seem to have found relief by making changes to the heat situation on the laptop, my guess is that the generic AC adapter charged the battery too quickly and made it too hot causing the shutdown. I would guess that anything that reduces the heat in the box helps including the ac adapter and maybe the condition of the battery itself. I don't know for sure, but I would guess that an older battery takes longer to charge and more heat is generated while it is charging.

This is all conjecture of course, but if you adapter is generic or your battery is old, you might want to look into these issues too.
