I own a HP Pavilion zd8000. it has three fans (lots of chat about this on the forums regarding heat etc).
Unfornately after an hour's use and using START>SHUTDOWN my laptop simply reboots, and I am only able to force a shut down with the power swith held for 4 seconds.
I have mailde HP for some supprt and they prompted me to upgrade the BIOS - I did this and the problem persists although I did notice that for the first time the third fan seems to come on after a while....
I have tried various POWER SAVING settings and also ran NORTON AV just in case.
This is driving me nuts because I dont want to damage my laptop by holding down the power
Can anybody ive me some guidance please? I would be very grateful
