Laptop Screen dark yet computer works with external monitor

My Compaq Presario R3000 monitor has gone so dark that I cannot see it. It hasn't completely gone out, the images are there, but too dark to see. Works just fine attached to an external monitor.

When I first turn it on, or walk away from it for awhile, the screen is good for almost 30 seconds, then it goes dim. If I lower the lid, it flashes briefly, then goes dark again. During bootup, it flashes briefly, then goes dark again. It's almost as if there is something overheating that's telling the screen to go dim -- or it thinks its overheating. Any ideas?

You have to use it more often to cure the capacitor in the inverter?

Compaq presario c500 has power and charges but the screen stays off disks will eject and you can hear the computer running just nothing on the screen.


hi there,
Please have it plugged it onto an external monitor to make sure that the problem is not with the LCD. Is there a backlight on the LCD or is it totally dark?
If the external monitor gives out an image it means that the LCD might be busted but do you know the keyboard shortcut to switch between the external monitor and the laptop screen?
You can try FN+ F5. if that does not work you definitely have to try it out on a external monitor.

Black screen on mu compaq R3000


You can try:

reseating / swapping the memory

booting the computer with the battery out.

You probably damaged the motherboard with the drop.

There are a few other things you can try too, but let's try the easy stuff first.

My compaq preasrio r3000 black screen cant conect to an external


have you any other A/V ports out ie Svid etc if so try that via an A/V lead, if that works reset your bios settings to minimal settings, if that doesnt work search the 'net someone somewhere has had the same problem! try shining a flashlight/lamp onto the screen whilst booting up, if you see anything on the screen then your inverter is definatly gone and yes it could still be your inverter! your laptop may have software/hardware issues with an external monitor?

Compaq Presario R3000 dim screen but not dark


Sounds like the auto-dim in the BIOS is set too low. Fortunately the Compaq R3000 allows you to adjust the brightness right from the keyboard. Hold down the [FN] function key while tapping the [F8] key will brighten the screen, while [FN]-[F7] will dim it. The settings are different for running on AC power and battery, so you must do each individually.

Compaq r3000 dark screen


If you already replaced the inverter and the screen still continues dark, you need to replace your lcd screen. Your video card is good due you have signal with external monitor.

Black screen!


lets check a couple of things. I'm sure you know that a laptop can be hooked up to a external monitor or projector, There is a button usually F5 Or close to it that will turn your monitor off and send it to the external one. In some models of toshiba this will stay in effect even when you turn it off. You can toggle this setting by holding the FN key down and pressing the appropriate "f" key. try this first before you chuck it. There also may be a problem in the bios. Let me know how it turns out. Take care..Be mucho blessed... Mark
