So I have a HP laptop that will power on, all the blue lights on the system will light up, the fan kicks on but the screen will not illuminate. I took it into Circuit City where I got it and they could not do anything with it. I did an online chat with HP tech support and they stated that because it is out of warranty there is nothing that they could do other than have me send it into them to look at. They want $100 just to look at it. Is there anything that I can do on my own to see what is wrong or perhaps fix? They estimated that its going to cost $800 to fix if it needs a new mobo or screen. Motherfucking HP. Ideas, thoughts or suggestions?
