Check the display cables , and if you have one test a different monitor on your computer.

If this is not a sceen problem, then it is an internal fault possibly the motherboard.

Try first leaving the PC power cord unplugged for ten, fifteen minutes and check if PC restarts afterwards.

Blank screen - reset monitor settings first
connect the monitor to another computer

you can't access bios if you can't see anything.
if the monitor works fine, open computer case, locate bios battery and remove it, re-seat battery after 3-5 seconds.

These are things you have to research and investigate:-
1>Wake-on-LAN (most likely reason)
Those light on network and motherboard indicate "wake-on-lan" and other features are active on your computer. In this mode, when the computer is powered off, the network card is still active waiting to receive a special wake-up packet. When it receive that packet, it power on your computer and boot it up. This is used by computer support people in corporate environment for maintenance of computers during non-working hours without going to each computers to power them on. 

http://en.wikipedia.org/wiki/Wake-on-LAN

To disable, you can check is in DELL Bios setup, there will be option of disabling "Wake-on LAN" feature for that computer.

2> standby mode
When you press computer power button, the computer may goes to standby mode - ( there are other mode like suspended mode and power off mode ,but in both these case the light should completely turn off). 
Hope it helps :)

    else go into power options in control panel, have a look in there, there are some options about sleep mode and hibernation, oh and go into the BIOS theres some settings (usually) along the same lines...


  • AbdulRahiman S Nov 28, 2008

    rather i would suggest going to the Dell website and making sure you have the most up to date drivers, including chipset drivers.

    If that doesn't fix the situation you can disable standby by going to the control panel> Power Options, select each theme and disable standby, also goto the advanced tab and make sure your power button doesn't cause your computer to go into standby. Note that disabling standby doesn't actually fix the issue, it just disables standby.

Unplug your power supply from the wall.
Take a screwdriver and undo the 4 screws on the back of your computer that are holding your power supply in place.
Just take a look around the motherboard to see if there are any cables from your power supply that are loose.

Make sure the keyboard and the monitor is connected properly. Unplug the cables and then plugged it back properly.

Disconnect the main power source and then press the power button for five seconds. This is called flea power.

Now put the power back in and then turn on the computer.

Thanks

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."

Power save mode


Yes, you arent getting a signal to your monitor from your video card. Try replacing. If its onboard then the Mainboard may be bad. These machines are known by Dell to go bad and is covered under warranty, provided you still have it.

The message you are getting is coming from the monitor, not the P.C.

Its telling you you it went into power save since its not getting a video signal from the P.C. Check connections as well.

If your using any kind of splitter, remove it and connect monitor directly to P.C. to be sure.
Good luck
