Monitor goes into sleep mode after a few seconds

When I turn my computer on, the monitor shows the Dell logo and then goes into sleep mode.  I cannot change any settings or adjust anything since the monitor goes blank almost immediately.  My monitor keeps going into sleep mode. Also when it flicks back on I get millions of little blinking pixels. I thought at first it was just the monitor but I've switched monitors, no change. What is causing this and how can I fix it?

This is normaly cause by incorrect power management settings.

check power management setting in both windows and your computers bios

you will not need to worry about the power management settings of the bios when an operating system such as windows is loaded.

I have a dell studio 540 desktop, I need to restore to factory settings but my monitor will not stay open. It opens for a few seconds then immediately goes into power saver mode and turns off, how can


I see two things here, but need clarification;

1) Monitor goes to Power Saver Mode, then turns -> OFF?

Sure that monitor didn't go into Standby Mode?

2) Why are you performing a restore back to factory settings?
Pick up a virus?

Primer;
The monitor receives a signal. A video signal. The video signal comes from the computer.

If the monitor is NOT receiving a video signal, then the monitor will state No Signal.
This is for older monitors.

New monitors do not state No Signal anymore.
It's Power Saver Mode, or Sleep Mode.

If the monitor is truly OFF, the Power On button will Not be lit up.
Or the Power On LED light on the monitor.

Monitor power on LED is lit, or Power On button is lit?

Monitor is not receiving a video signal;

Use a monitor cable from a KNOWN to be working monitor, for a temporary test.
OR,
Use a Known to be working monitor, and it's monitor cable.

Need to find out if monitor cable is good.

Monitor cable checks out good?

Then problem is computer.

The two leading issues with desktop computer failure, is;

1) Computer is dirty inside
2) Power Supply inside computer is bad.

Please post back in a Comment.

My monitor seems to be stuck in sleep mode


This happens when there is no communication with video card. Check cables, re-seat video card, make sure monitor is set to correct mode. VGA (15pin blue), DVI (white), or HDMI.

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

My monitor shuts down after one second.


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 computermag-glass_10x10.gif 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."

Monitor goes into Sleep Mode immediatly upon turning on computer


Ok. I think "sleep mode" means that your monitor might not have a tight connection. Tighten all connections. Also, push the power button on your tower. When you gegt back, go to screensaver- power settings- and from there you can adjust.

Monitor keep going into "sleep" mode


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 displays breifly then goes to blank screen


If tried the monitor on two other computers with the same result -- definitly your monitor is faulty. Take it to the repair shop. To make double sure, run your computer with another monitor. If everything is fine now; you can blame the monitor.

Monitor doesn't work


Sounds like a bad video adapter. I'm assuming your emachines has an integrated video adapter. Put in a video card (with the power plug pulled out! Touch the bare metal frame of the computer with your hand before inserting the video card into the agp or pci slot Don't touch the motherboard). If you get video, you may or may not need to install drivers after that. XP has a lot of video drivers, but lacks quite a few of them, too.
