Re: My laptop turns itself of after 8 minutes - every...
Do you hear any fans spinning? it sounds like possibly the laptop is overheating although that is very quickly. do you have any more information? what does it do when it stops? when did this problem start?

When the CPU overheats then it will shutdown (i.e. thermal overload) and won't boot up again until it has cooled down.If this is the problem is not fixed then the CPU will eventually fail. A faulty fan causes the problem or the fan and heat sink assembly are cloggedwith dust. Check the CPU fan to see if it spins freely, if not replace the fan.
If the fan and heat sink is clogged withdust the remove the dust and make sure the vents are clear
and dust free. Use acan of compressed air to do this.

Sounds like something to do with a power saving feature either from HP itself or from Windows. It could also be that for some reason your computer is overheating, which it than shuts itself off to protect the processor. I would try playing with your power saving features, and cleaning out the fans.
Please check for the exhaust,is it coming properly and check the bottom of the Notebook is it heating ?
If heating then this is the issue with the processor fan.
If the temprature is normal then check in BIOS(leave the system in BIOS mode for 8 minutes) if then also it is turning off surely this is the heating issue.
If above mentioned is not working please revert.
Check your CRT boards on the end of the tubes for burn spots, and burnt components, check the resistors to make sure they are not shorted, burnt, and they read the correct resistance. Check the diodes to make sure they conduct in one direction only and are not shorted or open.
check whether the hiberbnate facility is on or off as it is turning off after 8 min or so. this can also happen due to overheating of the processor , it can turn off itself automatically try to increase the ram on the system
