Is your laptop computer screen pixels broken up like a bad television signal? You have shut off and tried to restart that laptop computer and the screen is green with pixels looking messed up like a bad television reception on satellite television. You can hardly see your desktop icons or even your wallpaper.
You can try powering off that laptop computer and removing the battery. Then you can power it back on. You can also try to use that laptop computer without a battery and just the active current direct current power adapter.
If there is no display with that laptop liquid crystal display and when you hook up to an external monitor to a video graphics array connection, then you might want to make sure you did not accidentally turn down the liquid crystal display brightness. Also, you can make sure you did not accidentally hit a function key that would turn off that display entirely or put that laptop into a different mode, for example a sleep mode. Does that laptop computer screen look similar to or the same when hooking it up to an external monitor?
If you did not accidentally change any liquid crystal display settings, then it might be a hardware issue with that laptop computer video graphics card. If your computer is quite new, Hewlett Packard Compaq should repair or replace it with their depot service. It sounds like to me either that liquid crystal display screen, liquid crystal display inverter board, or video graphics card is malfunctioning.
I usually hook up laptop computers directly to an external monitor to troubleshoot the quickest. You can make sure when hooking up to an external monitor to use a FN function key with correct key on that laptop keyboard to make a video display show up on your monitor and not that laptops liquid crystal display. If that picture on that external monitor looks normal then it is a problem with your laptop liquid crystal display.
If a picture on that external monitor is terrible or non-existent then it is an issue with your video graphics card or video graphics card drivers. You can check out this notebook display problems page from Hewlett Packard Compaq. Great you can at least use an external monitor for now.
That laptop video graphics card is fine then. You can follow some troubleshooting steps from the following laptop repair help article. Your laptops video graphics card is fine so you can just worry about those steps about your laptop screen.
If it resembles any of those sections where that liquid crystal display screen needed replacement, then I am afraid you need that liquid crystal display screen and or inverter board replaced on your laptop computer. At least it works on an external monitor for now. These tips were written for a Compaq Presario C762NR notebook personal computer, but can certainly be used as a basis to troubleshoot any laptop computer liquid crystal display problems on other brands and model notebooks and laptop computers.
