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.

so if you test the monitor on a known good PC it does what?
fails, then its the monitor
works then its the failing PC

all old HP monitors pre 2010 many had a sleep timer
so push the menu key on the monitor
then look for sleep timer and turn it off,
the monitor defaults to that mode, so dont push reset monitor or bam back to sleep mode it goes. so turn it off again.
all this is in the manual, lost yours, wana read it first?

read page 4.7 see that? (osd +advanced +) power saver OFF

quote, power button does this.
turns the monitor on and to standby or sleep mode.NOTE:
The power button is located on the top or front of the monitor depending on the model
off , on, and sleep.
my guess you are putting the power button i Sleep mode
a feature of this monitor.

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.

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.

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