I have a dell studio 540 desktop, I need to restore to factory settings but my monitor will not stay open. It opens for a few seconds then immediately goes into power saver mode and turns off, how can


I see two things here, but need clarification;

1) Monitor goes to Power Saver Mode, then turns -> OFF?

Sure that monitor didn't go into Standby Mode?

2) Why are you performing a restore back to factory settings?
Pick up a virus?

Primer;
The monitor receives a signal. A video signal. The video signal comes from the computer.

If the monitor is NOT receiving a video signal, then the monitor will state No Signal.
This is for older monitors.

New monitors do not state No Signal anymore.
It's Power Saver Mode, or Sleep Mode.

If the monitor is truly OFF, the Power On button will Not be lit up.
Or the Power On LED light on the monitor.

Monitor power on LED is lit, or Power On button is lit?

Monitor is not receiving a video signal;

Use a monitor cable from a KNOWN to be working monitor, for a temporary test.
OR,
Use a Known to be working monitor, and it's monitor cable.

Need to find out if monitor cable is good.

Monitor cable checks out good?

Then problem is computer.

The two leading issues with desktop computer failure, is;

1) Computer is dirty inside
2) Power Supply inside computer is bad.

Please post back in a Comment.

I am using a lenovo all in one ideacentre computer. The screen goes black for a few seconds then comes back


The screen goes black then comes back. When it comes back are you able to use the computer without any problems? When does this happen? Most times during the boot process the screen will fade in and out.

If this is not happening when you boot the system it's possible that your lcd screen might be going bad so keep an eye on it.

Message on monitor says " no analog signal".


If you are getting no post display on boot up (dell spash screen, and windows loading screen):

First step is to plug a different monitor into the computer. If this works you most likely have a bad monitor. If not then it is a hardware issue with the video card on the computer.

If you getting the post screen then you may have your resolution set to high, boot in safe mode (F8 on the key board right after the post screen) and chose safe mode. once windows comes up, right click the back ground and chose a lower resolution setting.

Hope this helps

I have an AOC monitor and a Lenovo computer. The monitor comes on and says no signal when and the goes off. I have no idea how to change the resolution when I can't get the monitor to stay on.


When the computer is booting up, can you see the POST? No matter what resolution you set the computer to, you should at least see that if your computer is indeed working. If not, make sure your monitor is set to the correct input (DVI or VGA); there may be buttons for you to go into a menu system to select input. If you can see the POST but the monitor says "no signal" when Windows loads, then you'll need to go into SAFE MODE to change the resolution. To select that, press F8 just when Windows is beginning to load.

I have a Vaio PCV-W20, and a few months ago the screen went black. The problem is that now I only get a visible screen for a few seconds and it goes black again. For example this is what I see when the...


Ok try this, at boot up press F8, when the Menu comes up, choose Safe Mode, but this time instead of going to the desktop, choose System Restore, follow instructions, and when the Calender type window comes up, simply choose a time BEFORE, the time it went faulty. This should completely restore you to working again. As long as there are NO other problems.

Try start up in Safe Mode press F8. Choose Safe Mode, when at the choice window, to select either Safe Mode Desktop, OR System Restore, chooses system restore and choose a time before you had the "Problem" and follow instructions. This should get you back.

Input signal out of range


You could try going into safe mode and make sure the correct drivers are installed and if they are then you can then set the correct resolution.

Computer monitor comes on for 1 seconds, flashes "analog power save mode" and then goes black.


Most monitors will say "Power save mode" when they can tell through residual voltage that the signal lead is plugged into a machine, but there's no picture being transmitted. The four states of a monitor are:

* Off entirely.
* Switched on, plugged into a computer but no video signal being received - usually displays "analog power save mode" or "digital power save mode" for a few seconds, then blanks. Comes back to life the moment a video signal is received. This state is the default in full power saving mode.
* Switched on, not plugged into a computer. Some monitors don't display anything, some go into power saving mode, some fly "CHECK SIGNAL CABLE" or a similar message around the screen. Picture is restored when the signal cable is plugged back into the computer
* On fully, receiving an image, and displaying.

Hope this helps.
