Monitor is in sleep mode

Unfortunately, this is a standard problem, as when your laptop goes into sleep mode, it shuts off power to the secondary monitor, without giving it the signal to go into sleep mode. You could try digging around your settings, but most likely you'll just need to turn off the monitor when you're not using it.

How do you shut off sleep mode? I take it you're using Vista, as XP has "standby:" mode rather than sleep. You first right-click the desktop, then click "personalize." from there, click on "screen saver," and then "change power settings." from there, look on the left hand side of the window and choose the option you want to change. Probably, you'll want to "choose when to turn off the display." Hope this helps,

go to control Panel, Hardware and Sound and then select Power Options. There are several plans to choose from or you can create your own Power Plan. Choose when you want the display to shut off but make sure the "Put the computer to sleep:" is set to "never". The save the changes.

Sounds like a bad graphics card. Try using monitor wit another computer and see if the problem still exists. This rules out the display.

Try hitting the "Windows" key on your keyboard to bring it out of sleep mode. The "Windows" key is generally found on the bottom row of the keyboard, near the Alt and Ctrl keys, and it has no letters on it, just the Windows logo. That key brings my Windows Vista machines out of sleep mode when other keys won't.

As for the power button, anytime you need to force a computer to turn off, you can press and hold the power button to do so. Usually, you need to hold the power button for 5-10 seconds and it will shut down. Use this option with caution, as it turns the computer off without running through the shutdown process and can cause you to lose data.

Hope this helps.

I have a LCD panel it is connect to to the LCD. I need to change a setting on the computer to make it stop going into sleep mode, however, now that it's in sleep mode, how do I get out of that so I can make the change?

Try change the keyboard, if the pc does not detect the keyboard or a key from the key board is stuck which gives something like tic tic sound. On the other hand the display from monitor "sleeping mode" indicates the VGA cord is faulty or monitor is no compatible to the PC's video card.

I turned my power off from monitor and tower and turned them back on simutaneously with the F8 key. It worked.

Sleep Sleep is a mode that the computer enters after being inactive for a set amount of time. Commonly, this mode will turn off a device or set it into a stand-by

Hit the keyboard keys. It is better to just turn sleep and hibernate off and just use a screen saver or tun it off.
