  Dell LCD monitor goes into "power save"... 
 Date Written 
Ryan Lane Oct 31, 2008, 05:28am EDT Report Abuse
I've got a Compaq laptop computer, it's used like a desktop, it pretty much just stays stationed on my computer desk, and I've also got this 22" inch Dell monitor that I plug into my laptop once a while. I'll use it like if I want to watch a movie on it or every once in a while I'll plug it in to use it as a default monitor while my laptop screen is shut closed. Anyways...

I hadn't used the monitor in a couple months, so I decided to go ahead and plug it in and just use it for a while. So I plug the DVI cable into the computer, press the monitor power button, and right away the monitor power button color turns from green to orange, and it displays "entering power save". I tried unplugging the DVI cables and power cable. I also shut down my computer, and rebooted, and the monitor acted like it was going to work... It was displaying the Windows boot up screens and all that. But then as soon as it was about to reach windows, the power button on the monitor turns orange as the monitor goes black and again reads "entering power save". I tried goofing around in the control panel as well, and I just can't seem to figure out what the heck is going on with the monitor.

Any ideas?

I've seen that happen when the computer is set to a screen resolution that the monitor can't support. Try setting your resolution lower if it is set high. (I don't know what the Dell 22" LCD maxes out at.)

It's a DVI/driver issue... Leave it for a while, then hook it up to your computer when your comp is powered off. Turn on the comp, and just after it hits your BIOS turn on your monitor, you should be fine.

Tennessee - I have messed around with the display settings. It doesn't let me change the screen resolution for the LCD monitor. When I change the screen resolution, it automatically goes right back to "1024 by 768". I hit apply, and it just resets back to that resolution. Don't think it is a screen resolution issue.

There is an option that reads "Extend my windows desktop to this monitor". When I select that option, my LCD monitor power button goes from orange to green, but it just shows the background desktop. That's it. When I deselect it, it goes right back to "power save".

Vel - I tried to do this. Didn't work. It just keeps wanting to kick back into power save.

This is annoying. Any other ideas?

This may be a silly question, but have you tried the external video port toggle?

I think the key combination is Fn + F4 on the Compaq laptop but I am not for certain.

Tennessee!!! Definitely not a silly question! Fn +F4 worked! Oddly, I never had to do this before though. It used to be that I just plug in my monitor to the laptop and it automatically turned on and started to work, I never knew about the Fn +F4.

Awesome.. thanks a bunch.

Great Ryan...glad that was such an easy fix!

Is it possible you've done a BIOS update recently or the CMOS battery ran down?

On some laptops, the behavior of the external video port is configurable in BIOS. Soooo, if the BIOS got reset to defaults for whatever reason, that could explain why it suddenly started happening.

Something you may want to dig thru BIOS for and see if you can set it back to the desired result.

I had this problem today tried all the usual reboot press f8 wait for something to happen etc - the problem started when I moved my work station and had to move my monitor from one room to another - rang Dell they said they would call back - and they did!!!

The advisor told me to simply take out the VGA lead at the back of the screen which has never been disconnected and plug it back in - and hey preston my big lovely screen is back again - so hats off to Dell - it was a dead simple fix. if you are having problems try this and see if it works.
