Go to your CONTROL PANEL and into the POWER MANAGEMENT settings.  Adjust the settings for time or to off.

Sounds as if your video card has no output.  Check to make sure your monitor cable is not loose.  If it isn't, your video card could have died.

Your monitor should work just fine - it uses a standard hdb-15 cable to connect to your computer.  \nMake sure you change the voltage settings on your power supply (of your computer) - it is usually a red switch in the back of your pc (by the power cord).

Check that the monitor cable is correctly connected.\nIf it is, then get a new monitor from some place with a good returns policy - just in case the problem is with your graphics card!!

Check the AV cable ( should be the blue ended cable that attaches to the Computer Tower)\n\nmake sure that is connected sercurely, Try moving the mouse, some monitors have a power saving feature where they will dim to save power...To turn this off \n\nControl Panel > Power Options > There should then be a box about power saving on the monitor un tick it.\n\nAlso if your using a flatscreen monitor chances are that it is backlighted...This could be an indication that your backlight is on it's way out and you may need to replace it.

Did you have a power outage?  Surge perhaps?\nSomething took out the power supply right?\nIf you aren't getting any kind of beep code or anything and everything seems to be reacting normally.  The very first thing I would do is check to make sure the monitor didn't get toasted!\nAlways verify the monitor isn't fried before you go to the MB and other internal parts of the pc for troubleshooting a video related issue.  Did you get responses from the hard disk, or cd rom after the power supply was replaced?

Does it return to normal on it's own or when you touch the mouse or keyboard? It could be your power settings....right click on your desktop and go to properties, screen saver, then down where it says Monitor Power click power and make sure they all say never then click apply. Hope this helps

Next time it goes blank, try pressing the menu button, if the menu comes up, suspect the video card.  If the menu doesn't display, replace your monitor.  Of course, check the cable connections first.

If your lcd monitor boot up with the pc and able to show the desktop, then 99% you are okay, 10 sec of black screen is normal unless it happen just recently. \nFor a pc to boot up to the desktop, the bios recognize the hardware then the loading of platform, there is not much to show unless you change the bios settings on some motherboard, so it should be generally dark.\nConnection between pc and monitor shouldnt be a issue as normally you won't touch that, if it's connected, it should work, otherwise it won't be 10 sec delay only.

I have the same issue with mine, I am not sure of what can be done yet, as I have taken mine apart and checked all the connections / cables pertaining this this LCD problem. However,Your laptop can still work with an external monitor. So for a short term fix you need to acquire another monitor / LCD Monitors are reasonably priced now.\nUntil we find the real fix....

How often does this happen?  Is after it consistent length of time?\n\nI think your friend's computer has Power Saving enabled and perhaps the monitor is scheduled to switch off each time.  Go to:\n\nControl Panel/\nPower Options/\nPower Schemes\n\n... and check the options at the bottom.  The monitor may be set to switch off after a time lapse as short as 1 minute.\n\nIf in doubt, set all of the options to never.\n\n'Hope that helps.

try changing your refresh rate to stop that, sounds like you have the monitor plugged into a power strip so its not saving the settings

First go to control panel > Power Options > Power Schemes > Settings for Home/Office Desk Schemes  and check whether you have activated any auto turn off for HDD or Monitior (say after 10 minutes). \n\nCheck whether you have activated any screen server which gives you a blank screen after certain amount of time.\n\nIf it is not this please make sure your data cable, mouse cable and keyboard cables are properly connected to your system. \n\nMake sure that no automatic shutdown tasks is created earlier.\n\nAlso run a virus scan so as to make sure that there is timer based viruses which activate them selves in a sp. time.
