HP screen goes off

September 21, 2012 11:08:32 PM


I have an HP dv7-1448dx, I have the following issue. First let me mention a friend try formating my laptop from home premium to Ultimate. but he came back with it saying it doesnt work anymore. that computer will turn on but not the display. so I search on google and found out about thermal paste so this laptop has an expire warranty I dicided to do it my self. I change that termal paste, re-assamble it. and that screen when on. The first thing I see is that windows is not active because i get that message. but that display when off and it sound it like that speakers did too, but the power, volume and wireless keys are still on. I turn it off then back on and I get the HP log but it goes of right away. that next time I try to access the BIOS and I was able to navigate for a minute or two and it goes off. Any Ideas what could bee the problem also, I will like to mantion that it doesnt get hot or anything like that.

Thank you
