I have a Dell Studio 1749 running Windows 7.
So this epic started in April (http://www.bleepingcomputer.com/forums/t/493181/laptop-screen-white;-external-monitor-works-fine/#entry3039854). Summary: The laptop screen went blank but I still got an image on a connected external monitor. I have since replaced the motherboard, power input jack, internal monitor/display, and the cable that goes from the internal monitor/display to the motherboard. When I turned on the computer after installing the motherboard, I got a series of 6(ish) loud beeps. The screen was still black. I remember that the beeps means it can't find the hard drive (yes?). But I don't know if the screen should be displaying something with the beeps.
I would appreciate any input. I know most of you will say, "Scrap it and buy a new one!" But I can't find a decent computer that I like (that runs windows 7) in my price range. And I'd really rather not lose the money I have put into fixing this thing.
Thanks for your help,
