About 3 weeks ago my laptop's screen stopped working. I turned it off for the night and when I turned it back on, there was no display. The backlight still worked and I could control the brigtness of it, but that is about all I could do. When I hooked the laptop up to an external display and checked if the internal display was still there. it wasen't.
I just want to know if this problem has anything to do with the hardware or the software.

I came across your post about the display issue, and wanted to help!
To test for a defective display, use the following steps:
Connect the computer to an external monitor with a VGA or HDMI connector cable.
Connect AC power to the notebook and the external monitor.
Press the Power button on the computer, and then press the Power button on the external monitor.
If an image displays on the external monitor but not on the notebook display, download and install the latest BIOS, the latest graphics driver, and the latest CPU chipset. See the Obtaining Software and Drivers support document for more information.
If there is still no image on the notebook display, there is a hardware problem with the notebook display. Contact HP for repair service.
