Hook up a monitor from your desktop and see if it will work with an external monitor. if it doesn't work, you have a video card problem which would require replacement of the system board. if it does work, your backlight on your screen is likely burned out and the screen will need to be replaced.

    no, it should go right away. you should be able to see at least the windows loading screen. it sounds to me like it's an issue with the onboard video card. Likely the same part as the system board.

I've tried pressing fn and f7 at the same time and it won't work, neither will any of the other suggestions. And my computer keeps saying that the touchpad is enabled. Is there anything else that I can do...


Try hitting just the F7 key only. I had an issue with an HP Mini laptop and was hitting the Fn and the F7 key and found the key combination didn't work when I pressed both Fn and F7. But it did work when I just hit the F7 key (even though "F7" was written in blue, the same color as the Fn key, it turned out that I didn't need to press Fn and the key for F7 to gain the functionality of the F7 key. HP tech support informed me of that when I called them due to a similar issue I experienced a while back).

Try to hit F7 alone. That may help you out.

As for the touchpad, it should be enabled. (Unless you're using a different pointing device and want it disabled). There are options where you can turn off the touchpad on start up, but I would advise against doing so.

Broken screen, external monitor via VGA won't


Press "Fn+F7" once, wait a few seconds, and press it again, to "cycle" through all the possibilities (LCD-only, VGA-only, both).

Try the monitor with some other computer (desktop or laptop) to see if the monitor works at all.

Restart your computer -- does the initial "splash" screen (showing CPU speed and RAM-test) show? Does the "Windows" screen (with the crawling worm) show on the external monitor?

Screen is broken but now it wont connect to monitor...


after connecting your external display, hold the fn button and press the f7 button (f7 on most, if F7 doesnt work, just press each of the function buttons)

Faded laptop screen, but fine with external monitor


Your screen is most likely set at a high brightness, which can be fixed by turning it down. To turn the brightness down, press "fn" and "f7" at the same time. keep pressing and releasing until the screen's brightness is good! If you make it to dark, then press "fn" and "f8" until it is lighter.
Hope this is a help,

LCD Problems HP Pavilion DV2000


It sounds like your backlight in the LCD screen has died. However your system should work with an external monitor. When you connected up the monitor to the VGA connector did you change the settings on the system to output to the VGA output ?
Try connecting the monitor before the computer is turned on - then once booted hold the Fn key and press F7. Then pause then press Fn and F7 again to see if you can get the external screen to show your screen. It sounds like a dead back light though.
