Dell Monitor in Power Save mode

read the monitor manual.. Did you try unplugging it and see if it reset to default when you plugged it back in?

Hello,
If your monitor is going in Power save mode it can be cause by following reasons.
>Check the data cable going from monitor to your Dell Dimension 4600 Tower is connected properly.The connector will be blue or white in colour.
>If the Dell Dimension 4600 Tower is powering on.

If still in power save mode then try to shutdown Tower and monitor,disconnect power cable from tower and monitor.Hold the power button on tower for 15 seconds.Then again try to connect monitor and check,if still nogo,and if tower has no lights then issue with motherboard or video card or power supply.If possible try connect spare known good monitor.

Thankyou

I don't know if there is a monitor with a function button to turn off the power save mode.
As far as I know the power save mode of the monitor can be found in the display setting of the windows..

Anyway... If you want to turn off the power save mode of the monitor via windows display setting then here is what you need to do:

On control panel, double click display settings.. click the screen saver tab... on the lower portion Press the "power" button.. Select power schemes tab.. Change the settings of" turn the monitor off" to "never"
Click apply and then OK..

Hope it gave you an idea..
Much appreciated if you rate this help...thanks..




Uncheck the box

First, try it on another PC, check or try another VGA cable, if it still does not work then you need to open it up. Dell monitors are known to have bad solder connections, bad caps. See my photo albums of failed Dell monitors to get some idea what to look for.
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed DELL monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

If your computer is indeed running, simply unplug your monitor from the wall, and then plug it back in. This will bring your monitor out of power save mode instantly.

old post 2017, 1 year old. Desktop and very old monitor.
This old monitor is CCFL and those fail super easy now.
built in 2005, backlamps are mostly dead now.
VGA cable? or DVI#1 or 2 port connected
the monotor told you PC went to sleep mode
I believe it. I bet the monitor works on any other PC you try, I bet.
so put the PC VISTA in into presentation mode.
(like we do with presentations, or kiosk mode, or using a nice DLP projector in theater)
just one app does this below
or learn to use
control panel, + Power settings, and advanced.
turn off all sleep modes,all hibernate modes.
turn on all wake-on modes, for sure USB ports.
make sure device manager is not showing dead devices (chips) if it is , that means get the missing drivers from Dell, for VISTA. Dell has them on your support page
and we are not DELL.

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 computer 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."
   

it might very well be an issue with the new PC's video hardware. If the monitor gets no signal within the first few minutes then it will automatically go into power save mode. Also, just as a troubleshooting idea, recheck the vga/dvi connection on the back and make sure it is seated well. You might also have a bad monitor. One week old equals exchange.

check the primary settings for your default video card.

Turn the whole pc off then back on. If the LCD stays in power save then I would try a diffrent monitor on the PC. If that fixes it the the monitor is probably stuck in power save. Check www.lcdrpair.us for parts and instructions.
