My monitor won't come out of sleep mode

My monitor and CPU went into sleep mode and the monitor will not stay on now. I unplugged it turned it on and goes off after a second or two. No matter what I do it will not stay on for more than a second or two. The "W" at the bottom of the monitor flashes like it does when the CPU or monitor is in sleep mode. Is there a fix for this?

When the computer enter the sleep mode, it is possible that the computer remove the check mark from this output activation.

When you have multiple ouptut like a internal LCD and output on a monitor, when going into sleep then waked up, laptop reactivate the internal LCD without reactivated the secondary monitor.

you could need to go in desktop property and reactivate the secondary monitor with the check mark listed : Activate.

If you only have one monitor but still a dual output card or two separate video card same thing can happend. try to connect the monitor on the second VGA or HDMI output and see if the video goes there.

then reactivate your secondary output and make it principal.

Does also happend when your computer is connected to a UPS power and your monitor is directly on the sector. (laptop issu also)

if a brief power outage arrive then the monitor shut down (no power) and the computer continu, as there is no monitor on the output any more Windows will automatically deactivate this monitor. when power goes back, this output is no longuer providing video. I suggest putting the monitor on a UPS as well.

SOURCE: I turn on my monitor

It may have dying power supply due to bad caps, see pictures here:
http://s807.photobucket.com/albums/yy352/budm/Westinghouse%20LCM-22W3/

If you are going to DIY and already try the monitor with another PC, and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, 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 monitors to get some ideas what to look for: http://s807.photobucket.com/albums/yy352/budm/
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Forgetting that the computer was on, I went to turn it on and shut it off while in sleep mode. The screen won't work.


A monitor does not normally save any states such as sleep. If unplugging the monitor from the power source for ten to twenty minutes and re-plugging it in does not fix the problem check and see if the monitor's menu comes up.
Even in sleep mode, the menu for the monitor should show. If it does, try resetting the monitor to factory default settings. If the menu does not show up, then there is an issue with the monitor.

Here is artical I found on how to disable sleep mode on a monitor, this would be for VISTA or 7, if you are using XP it's a bit different. ____________________________________________________________ How to Disable Sleep Mode on a Monitor

Your computer monitor or laptop screen will enter sleep mode after your computer remains idle for a set period of time. You can disable sleep mode if you prefer the screen to remain illuminated. You merely need to change a setting in the Windows Power Management properties box.
Difficulty: Moderately Easy Instructions

  1. Click "Start" and "Control Panel".

  2. Click "System and Security" and "Power Options". This will bring up a new dialog box.

  3. Click the menus to the right of "Turn off the Display" and set them both to "Never". This will disable sleep mode.

Hello,
May be the problem comes from the Cpu.
Try to see if the cable from the monitor is firmly connected to the cpu.
One thing more may be the vga card is having problem.
Try to test the screen with another Cpu. Or the cpu with another monitor.
The amber mode is normal as the screen is not receiving signal from the cpu.
At times the memory chip also report this problem (no display or sleep mode)
Do hear any beep sound or any other Errors??
OK try this

Does samsung monitor save power in sleep mode?Or will it just displays black all over the monitor?


yes, all monitors work directly with the cpu, the cpu sends message to the monitor, so if the system is in sleep mode, automatically the monitor stops work excepts the cpu comes up again then the monitor wakes, in a nutshell, a monitor is connected to power while in sleep mode but has no signal to function

I have a Dell Inspiron 530


I have a Dell Inspiron 530S, and it exhibited the same symptoms as rguggemos's & Wilburollie's.

I can put it to sleep, but when I try to wake it, it won't. The screen will stay black. I can hear the drives spin up, and the fans go on FULL blast, and the blue power LED stays flashing, but the computer will stay like that - no picture or anything. Then I'd have to press & hold the power button to force it off, then power back on. Not ideal.

The solution that worked for me?! On boot, at the "DELL" logo, hit F2 to enter the BIOS setup, go to Power Management, and change the standby mode from S3 to S1. The difference? S3 is a "deeper" sleep, w/ more components powered off, which is better, energy-wise, but it is more difficult to wake from. S1 is a "light" sleep. Give it a shot! Maybe it'll work!

Good luck!

- Mike

Stolen from another forum:

S0 (Working) is lit. The CPU functions in entirety; the conservation of power is on a basis of by-device.

S1 (Sleep). The CPU is stopped; The RAM is regenerated; the system functions in reduced power.

S2 (Sleep 2) The CPU does not have any power; The RAM is regenerated; the system is in lower mode of the S1.

S3 (Standby) The CPU does not have any power; The RAM regenerates at minimum; the power supply unit is in mode of reduced power. This mode is also called “Save to RAM”.

S4 (Hibernate). All is powered off, but the memory was saved like temporary file on the hard drive. This mode is called “Save to disk”.

S5 (Off) Everything is shutdown. Means you need a full reboot.
