Re: Monitor goes to sleep and doesn't wake up

Usually if the monitor goes to sleep in means that there is not a video signal.  However, if holding the power button down on the monitor? will wake it then the issue is the monitor.  If you are holding down the power button on the PC then you have another issue.  Which power button are you holding down?

 

What model PC and operating system are you using?

Re: Monitor goes to sleep and doesn't wake up

I have an HP w1907 and I Have the same problem.  My monitor just goes to sleep leaving me staring at a black screen.  I have tried everything to wake it up.  I fiddled with the cables, turned the computer on and off, i unplugged it a few times but still nothing.  It turns on for literally a minute and then goes to sleep mode.  Does anyone have a last suggestion for me to try before I give up and toss this thing out the window?  It's so frustrating!

Check your monitor on another PC to eliminate it as an issue.  If it checks out OK then the issue is your PC.  At that point it's either the video card or the motherboard in most cases.

 

If your PC is going into sleep mode and your monitor doesn't wake then you might have a video driver or bios issue.

Re: Monitor goes to sleep and doesn't wake up

OK it may not help but it may be an interesting point. We have four of HP dc7700 small form factor PCs in our lab which do the same thing. I have never found an answer to this problem, in truth, with Windows XP. I can take the same monitor and connect it to a HP dc5800 and not see the same issue. Prior to going on a trip to St. Louis I did a dual boot with Ubuntu 10.4 on one HP dc7700 that has been very bad about this.  After returning to the office a week later the PC is still responsive and not head dead. I previously went through the power settings with XP and set the PC to never set the monitor to sleep so it should never goes to sleep now but it still has the same issue when on Windows XP Pro SP2 or SP3. It goes head dead. So far with Ubuantu it remains faithful. I would recommend, as has been stated, updating the BIOS and drivers but also check the power settings and set the PC to never put the monitor to sleep. It may help. The monitor just does what the PC dictates. If the PC is an HP PC check the forum pages for PCs for an answer as well.

Re: Monitor goes to sleep and doesn't wake up

Bur,

 

Go into the monitor's menu and look under Management for Power Saver mode.

Re: Monitor goes to sleep and doesn't wake up

I started a thread on my own forum because there is a lot of discussion about this. It is out of order and I don't doubt for a second that HP knows the length of life of the components in their monitors. All of these things are tested and your talking about components used for years. They know the score by now.

Re: Monitor goes to sleep and doesn't wake up

My monitor goes to sleep when ever my computer starts up. If I hold down the monitor button it the monitor comes on then goes right back to sleep. My video cable is hook-up as it should be. Does anyone have any ideas
