Three months ago, I replaced the LCD, cable, inverter and battery on a Dell C800 running W2K Pro and updated the BIOS. Recently, the screen started to black out intermittently and then stopped working at all. I am able to use the laptop on an external monitor. I've toggled the FN + monitor key, run Windows Update and checked the driver, resolution and refresh rate, but to no avail.
Later: I clicked the "i" hot/access direct key for the internet and the screen came right on, but I have no idea why.
Later still: Hitting the "i" hotkey didn't work a 2d time. A restart sometimes works, but other times it won't. It's not in standby, because I can see the image faintly and there's no pin on the deck to get stuck. I updated the BIOS, did the virus scans, defragged and it was working, but today, when I restarted, it wouldn't and on another restart, it would. Any ideas? Thanks.
