Monitor keep going into "sleep" mode

My LCD Monitor (Dell) keep going into "Safe" mode 1 few second after the computer boot up. In this mode, the monitor go blank to save energy. It is like the computer has been idle for a long time. If I turn off and on the monitor, the screen display for a couple second and then go into "safe" or "sleep" mode again. thanks

Check the power setting in control panel of windows. If you have a monitor from another computer swap them and see if the problem stays with the computer or monitor.

Monitor goes black seconds after showing desktop


Does your monitor go black because it went to sleep, does it turn off? Do you have any lights on the monitor to indicate what it is doing?

Also I would boot into safe made by rebooting the computer & tapping F8 when the bios appears. You should be prompted with several options, one of which is "Safe Mode". Choose this & report how the monitor behaves.

I have the same problem as this one does. my monitor goes black when windows boots. I can see the computer load at fist, then when the window icon shows. the screen goes black. WHY ?? im thinking there is...


you can try Fn + F8 and see if the display was toggled for external (Wait about 15 seconds before pressing a 2nd time) that is the keystroke from (LCD, External, LCD and External)
If no go, see if your system keeps video displayed in the safe mode (F8 at boot, select Safe mode from the boot menu)
you can also run diags on the LCD (Power button + D) or PSA diagnostics and see if the video stays on out of the operating system (Power +Fn)

My Dell monitor goes to sleep right after windows xp starts to load and it won't come on after that. my computer is still running but the monitor is a sleep. I have hit f8 and f12 with nothing happening....


Go into safe mode
Under settings, control panel, power options set "turn off monitor to never
reboot

I think this is not a sleep problem but the incorrect monitor settings were set. This will cause the screen to go black when the OS comes up. Boot in safe mode and change the display settings
to 640x480
OR
in safe mode, delete your monitor. When you reboot it will load a default monitor and you should be OK

Computer in safe mode and monitor will go to sleep mode....help what can I do...my husband tried everything....


First, Shotdown your computer from start ,
then remove your computer power, remove VGA cable, remove VGA power cable. then
1- connect vga cable to computer.
2- connect VGA power but do not power on.
3- connect computer power on but do not turn on
4- turn on computer first and 3 second turn on your lcd.

if NOT try powering on computer then Monitor then power the computer then monitor.
IF NONE worked, YOU may have LCD that need drivers from manufacturing, some newer models required that, Specially for vista.You may use older Monitor to get drivers to computer and extracted, then you may connected, you will have solved the problem.
Goodluck

Sharp light turns green thern turns yellow screen goes black


it is going into sleep mode, good luck with this.... i am currently asking how to get my hard drive to quite putting my monitor into sleep mode.

although it hasn't worked for me because my screen stays black, one of the options given to me is to try to start in safe mode and then adjust your settings to "never" on the energy/sleep/hibernate mode

some one else suggested that i remove and reseat the video card

hopefully one of those will work for you

Fuzzy display on LCD and External Monitor


it sounds like you may have an updated driver that doesn't work with your machine. boot into SAFE mode. on a dell it is hitting the Del button for most of them as it is booting up. then choose safe mode. For other dells it is F1 or F2 you just keep hitting the button while its booting up until you hear it start to beep at you. then look for safe mode. while in safe mode you can then change the driver, but for those specifics you have to go to dells web site. http://www.dell.com/support/home/us/en/19/quicktest?c=us&l=en&~ck=mn
