On a Desktop? Reboot, Open Control Panel, Power Options, set to High Performance, Advanced Power settings. Set Hibernate and Sleep to Never. Shut down your computer when not in use, it will last longer and a reboot everyday will reset the machine.

SOURCE: 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.

SOURCE: Compaq Presario stuck in sleep mode

Connect the monitor to some other computer, e.g., a notebook, and see if it does the same thing. If it does, then the monitor is the problem.
If it does not, then your computer is not putting-out any "video" signal, and so the monitor goes to "sleep".

If you have MORE than one VGA-output port on your computer, connect your monitor to the "other" VGA port.

Or, press-and-hold the ON/OFF button on your computer, to force it to completely shutdown.

SOURCE: My monitor has kicked into sleep mode and won't "wake up".

Unplug all the Cables from Compaq Presario 5103 CL and leave the Keyboard, mouse and monitor cable pluged in.

Now make sure the power cable of the monitor should be pluged in and the power cable of the tower should be pluged in.

Now to check if the montor is fine just unplug the video cable only which will show no input signal on the screen. If it shows this signal the monitor is fine. Plug back in the video cable.

If the monitor is going to sleep mode it might be possible that the old computer ( Compaq Presario 5103 CL ) is in stand by mode. hit any key on the keyboard and it should come back .

If it is not in the stand by mode then do one thing. Check the same monitor with the new computer. If it is working. Perfect ..!

Do one thing now ..!

Unplug all the cables from your old system and then press the power button for 30 sec and let it go. Now plug the keyboard, mouse and the monitor try again.
If it works Perfect. If not ..!

Then you need to open the tower and check on the processor FAN is it running..? If its not running you will not get the display as the fan is responsible for the display on the screen. Otherwise...!

Check the Tower possibly the Tower is not getting the power.

Try these steps and let me know If it works

How to wake Dell All in One, Win 7, from sleep mode


In Windows 7, there is a bug, if you put the PC in sleep mode when the system is running on batteries then it may still drain out the batteries and you cannot wake it up. In this case, you need to connect the AC power and reboot the PC. If you put the Pc to slepp when the AC power was connected. Then there are no issues and just by pressing the enter key it should come out of sleep mode. Sometimes - depending upon settings - you may need to press the Power button the PC to wake it up from sleep mode.
If you have already tried all this, then please go to the Power settings in Control panel and check all the setups that exist. You may need to change some of them.

How to wake msi u130 from sleeping?tnx


If it is in sleep pressing any key or moving the mouse will generally wake it up. If you left the computer unplugged in sleep mode then it most likely ran out of power. If your using hibernate I would recommend not using it as it has so many issues.... :) If you have to hit the power button to wake it up then it's either shutdown or in hibernate. FYI there will generally be an amber light on to indicate sleep mode. If no lights it's most likely not in sleep mode.
Comment if you need additional assistance.

Waking from sleep mod


Hello
The hinge is a very fragile part of the Macbook. In the hinge goes all the video and sound cables, as well as the backlight power. You can have a hardware problem here with your connectors.
However the sleep mode can also take its time to wake up:
- The hard dive needs to wake its 5400 rpms - The system has to wake - The video has to wake
I would think that a fast internal hard drive, as a SSD drive for example, will wake up much faster.
Hope this helps

Cannot get me monitor out of sleep mode, please help?


Hi

Pls check the power management properties in device manager to check if the option to wake the computer from sleep for the keyboard and mouse are enabled.
You may also try to change the power plan or create a new power plan and check if you are able to wake the computer from sleep.
If this problem started a few days back, then you may try to do a system restore.

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