My (dell) laptop monitor turns off automatically when i plug my powercable into it. It just turns black. if I move the mouse I know that thecomputer is still responding, but the screen won't show me anything have same problem thought i had it fixed once but then it crashed and i dont rember how i fixed it last time it is not a power problem i think it is a DELL problem!!!!!!!!!!!!!!!!!

In the Control Panel, select Mouse and the Pointer Options tab. Uncheck "Enhance pointer precision" and the problem may go away.

The monitor has failed, it is almost always cheaper to replace it than fix it.

motherboard and graphics adapter may need replacement

Dell monitors automatically go into power-save mode after a preset amount of time when the computer is inactive. The Dell monitor will go completely black, instead of showing a screensaver. This doesn't mean that your Dell computer has shut down. Instead, this allows your monitor to essentially turn off until it's needed again. You can change how long it is before the Dell monitor goes into power-save mode by changing your display settings.

1. Step 1 Press any key on your keyboard or move your mouse. Either will turn off power-save mode. Alternately, you can press the power button on your Dell computer tower or laptop.
   
2. Step 2 Press any key a second time if the monitor goes from power-save to stand-by mode. Stand-by mode allows the screensaver to appear.
   
3. Step 3 Enter your user name and password into the login prompt if your computer requires a login. Press "Enter" to begin using your Dell computer.
   
4. Step 4 Change the display settings on your Dell monitor to prevent your monitor from going into power-save mode prematurely. Right-click anywhere on your desktop and choose "Properties." Click the "Screensaver" tab and press "Power." Beside "Turn off Monitor," choose a time amount from the drop-down list and press "Apply."
   

Try this. it will update your drivers. This might be the problem.

Can you hear the Windows startup noises but can't hear it?

Does it work plugged into an external monitor? (Any good CRT or flat screen should work.


Be sure to plug in the screen before you turn it on.
If it doesnt output to the LCD automatically you may have to hit FN-F8 to switch to external.

If it works on external monitor you are just dealing with a screen problem of some sort - either a bad inverter or backlight in the LCD most commonly...

Let us know.

please be specific, your question is not understood properly??

Hi, You may want to try and unplugging the power and video connectors of the Dell monitor. Check for anything out of the ordinary with the AC plug and the video connector. If none, plug them back in making sure that they are snug and fitted properly. If problem persist, see if it is possible to rotate the way the AC plug is connected to the mains (sometimes this works and can be done if you are not using 3-prong or the uneven 2-prong AC plug. Sometimes, this can also be done on the other end of the AC plug). Check your docking station (though unlikely but possibly). If still a no go and your laptop works ok, then your external monitor needs some looking at. This would involve circuit analysis and component level repair. Perhaps your best bet is to have a qualified professional take a look at it. Good luck and pls post back how things turn up or if you need further information. Kind regards.
