I have a HP Pavillion dv6000 laptop with a nvidia graphics and a AMD Turion X2 64 processor. I am having troubles keeping it turn on. Sometimes I can turn it on and be using it for a little bit and with no warning it will just go black like someone unplug the power and battery. Normally you can get through a download like download avast. Once it goes off if you push the power button it will light up and sometime get to the welcome screen or hp screen before shutting right back off and sometimes it will go off before the hp screen comes up. Once you let it set a bit it will finally come back on and repeat the same process again. I first thought maybe it was overheating and put it on a air vent and had the air blowing on it the whole time. It stayed running the whole time the first time it was on the air vent. I tried it again a little later on using the air vent and it shut off while on it. It was plenty cold enough to the second time when it shut off while on the air vent. Can anyone give me some advice on what's going on with it or how to fix it or even if it worth fixing?
