My laptop turns itself of after 8 minutes - every time i turn my laptop on it lasts for about 8 minutes then turns itself off automatically how do i stop this? My HP laptop keeps shutting itself off after about an hour without warning.

The very first charging-time of the battery should most-usually last 6-8 Hrs , and if you did not do the same i suggest you drain your battery to the bottom until it turns off by itself , then plug in the charger and leave it charging for 8 hours (meanwhile the phone should be turned off ) . should be fine after ;D

(in case you did everything as you should and encountered this problem long time after you using the phone , all you can do is replace the battery)

Some computers have an option in the BIOS or System Setup Menu to turn the laptop on at a particular time. It's a good feature for people who turn their laptops off at night because the first thing a computer does when you turn it on is to load all the startup software, then begin downloading and installing any updates it might have missed while it was turn off or start running a virus update or scan. That's why computer seem so slow when you first turn them on for about the first 10 to 20 minutes or so. So if I turn my computer off at night and I know my day gets started at 8:00am every morning, then I can set my computer to turn itself on every morning at 7:00am by itself. That way when I go to use it, it's good and fast.

Let the car sit undisturbed for 10 - 15 minutes, then try to start it. Check the owners manual if you have it. Sometimes, on various cars letting them sit awhile will allow the system to reset itself. On others sometimes rapidly turning the key from off to on, without turning to start 3 to 8 times within 10 seconds and then on the last turn to the on position leave it there until the horn chirps, at that point turn the key directly to start, or turn off first and turn to start. If all this fails, a dealer can reset the system.

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.

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

Maybe your computer is overheating and turning itself off, happens to mine sometimes but not as often as 8 mintues.

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?

If you are using windows go into the control panel and check the power settings
