Monitor standby

Hello,

I am currently experiencing a problem with my PC. The issue concerns the screen that automatically goes into sleep mode after being turned on; in fact, it indicates "no input signal" in the VGA section and in Recommended settings: "1680x1050 - 60Hz".
After a few seconds, the screen displays "monitor going to sleep". This happens when I put it to sleep, and neither the mouse nor the keyboard respond afterwards. So the only way I have left is to force it off manually by pressing the power button.

When I restart the PC, both the computer and the screen work fine, but when I put it to sleep and turn off the screen, it stops functioning and shows what is displayed above...

This is an HP w2007v PC, Windows Vista Home Basic edition, I’m providing the site for more details: http://www.lcd-
compare.com/moniteur-HPW2007V-HEWLETT-PACKARD-w2007v.htm

I hope you can help me resolve this issue, thank you.

Good evening,

check the task planner to see who is responsible.

  Good evening,
  
  Thank you for your response.
  But are you sure that it's the task scheduler that is the cause?
  I just disabled and deleted some tasks, and I also have an error that appears when opening the scheduler: "an error occurred for the task RealUpgradeLogonTasks... Error message: the specified account name is not valid."

you deleted tasks without asking
can you perform a system restore
a screenshot would have been preferable
or reactivate the task that is causing the issue.

  I received the error message the first time I opened the scheduler before deleting and disabling tasks. I'm attaching a screenshot: http://www.cjoint.com/c/FCfuUZYZdQb

I see 6 tasks out of 7
the 7.. google... I suppose
driver booster you can disable the task and launch the software which will ask you for an update

consolidator is a tracker from Microsoft Windows

http://www.libellules.ch/phpBB2/mouchards-microsoft-t39413.html

update the graphics card driver if it is not
you have driver booster
check with driver cloud online

https://www.driverscloud.com/fr/demarrer

but also:

try to look here:

device manager
network card
right-click on your network cards (or wireless)
properties
power management
and make sure the first 2 boxes are checked if you see them

or
Allow the keyboard to wake the computer

right-click on the start button or Windows key + X
Device Manager
Keyboards > double-click on your keyboard
power management tab > Check the box "Allow this device to wake the computer"

same for the mouse in the device manager

  I just restored my system to an earlier time, before I disabled and deleted the tasks.
  The graphics driver is up to date, in the device manager I checked the box: "Allow this device to wake the computer" regarding the network card," for the mouse and keyboard it was already checked.
  
  But what I don't understand is why the screen displays "VGA: no input signal" when I put it to sleep and turn off the screen but it works when I restart the PC, displaying "Active" instead of "no input signal", I can use the computer...
  
  I am attaching additional screenshots:

Hello,
Your monitor indicates that the video signal from the PC is not within a range it can manage.
In your explanations, it's not clear whether you are talking about the screen sleep mode or the PC sleep mode, or the power button for the monitor or for the PC.
It's normal for the screen to display "VGA: no input signal" when the PC is in sleep mode, as it does not generate a video signal.
If the problem occurs when restarting the PC after waking it up, wait a bit before turning the monitor back on; if the PC takes a long time to reboot, the monitor may detect the absence of a signal before the PC sends an image in the correct resolution (low-resolution start).

I don't know any more than you do, but I'm looking into it.

  Hello,
  
  I'm talking about the PC's sleep mode. To be clearer, I can use the computer normally as long as I do not put my computer to sleep. As soon as I put it to sleep, the PC stays in sleep mode and so does the screen. If I turn off the screen and then wake the PC from sleep mode, when I turn the screen on it says "no input signal" and automatically goes back to sleep, and despite waiting a few minutes, it remains in sleep mode even though the PC is not in sleep mode...
  However, if I do not turn off the screen when putting the computer to sleep, it works when I wake the PC from sleep mode...

  Try disabling the "screen energy-saving" feature on the PC side.

  I just disabled the "power saving" feature on the PC side.
  I would like to know if it is a hardware malfunction of the computer or if it is a parameter that needs to be modified that is causing the problem?
  I read that it might be the graphics card, but that surprises me in my case since I can use the computer and it’s just when turning off the screen under sleep mode that it doesn’t work...

  Can't answer you.
  We can assume that the screen receives a sleep command but not a wake-up one.
  Eventually, instead of simply turning off the screen, unplug it from the power supply to clear any stored commands.

  I just performed the operation and no, it was unsuccessful.

All in all, even if I don't turn off the screen by putting the computer into sleep mode, the screen no longer detects the computer and stays in sleep mode.
But if I turn off the screen while putting the computer into sleep mode, when I turn it back on, it doesn't detect the computer and displays "no input signal."

  Are you saying that ultimately, with the monitor and PC in sleep mode, waking up the PC does not wake up the monitor?

    Yes unfortunately that's it.
    If it's just for a few minutes, the PC "wake-up" wakes up the screen, but if it concerns hours, it doesn't work.

  Hello,
  Still not resolved, then?
  Have you tried the screen on another machine?
  Have you tried using something other than Windows, like a Linux live version, for example?
  Because the problem is first to determine whether the culprit is the screen or the PC.

Hello,

Unfortunately, not always resolved, I can't try the screen on another PC, I'll try to get one to test it. Does it work on a laptop?

  Good evening,
  Yes, it works on a mobile device too, but you will have to configure it in the display settings (though I don't know exactly where, I don't use Windows).
  Have you tried lowering the display resolution?

    Hello,
    
    I tried lowering the display resolution but it didn’t do anything...
    I'm getting frustrated; I've been working on this for several weeks and I'm starting to think there’s no solution...
