Monitor doesn't wake up after powersave

Inside of my application, I use PostMessage (HWND_BROADCAST, WM_SYSCOMMAND, SC_MONITORPOWER, (LPARAM) 2); to turn off the monitor. However, when I use

PostMessage (HWND_BROADCAST, WM_SYSCOMMAND, SC_MONITORPOWER, (LPARAM)-1); (with a mouse_event), not to wake up the monitor.

I use 2 monitors connected to the GPU, Windows 8, directx9. On the other hand, I see that after sending the order to wake up the monitor (monitor still shows black) IDirect3DSwapCain9 * set to Null.

  • New place doesn't wake up after going to sleep

    I'm frustrated with my new coming 11 Pro, because 9 times out of 10, each time that I put it to go to the mode 'sleep', or he falls asleep, he wakes up not again. It seems to go to sleep very well and I push the button once to wake him up and vibrates it immediately for half a second. But then it never wakes or turn on screen for several minutes. I try the power button again to longer and eventually it starts and all my programs are closed and the computer restarted unexpectedly. What could be the cause of the computer to not again wake up after sleeping? It happens that my keyboard is connected or not, but if he plays well, then pressing the button start he wakes up. (It is rare that he wakes up actually sleep).

    Hi rpseekell,

    I'll suggest that you ask questions out of 11 in the forum of mobile devices.

    Good luck!

    Any help would be appreciated.

  • Re: Satellite P500 - 1C7 do not wake up after adding memory

    Hello
    I replaced the original memory of 2 x 4 GB 2x2gb.

    It works fine except that the PC doesn't wake up after a break.
    I have win7 64.
    How is that possible?

    The laptop worked before adding new modules?
    If so, then the problem could be related to new modules
    In this case I recommend that you test the other modules

    I use Kingston modules has never had any problems using these memory modules.

  • VISTA DOESN'T WAKE UP FROM SLEEP

    I RECENTLY REINSTALLED VISTA. AND THE PROBLEM STARTED THEN ONLY.

    I HAVE VISTA ULTIMATE ON MY LAPTOP. WHEN I CLOSE THE LID, IT WILL "SLEEP" FASHIONABLE AND ALSO WHEN I PUT IT ON THE MODE "STANDBY" MANUALLY, HE DOESN'T WAKE UP AS I OPENED THE LID. BUT MY SLEEP MODE INDICATOR HAS DISAPPEARED, BUT HE DOESN'T WAKE UP. AND AS LAPTOP SOUND FAN HEATER DOES NOT WORK.

    We have no idea why you need to reinstall Vista.

    You had then some serious hardware problem that would not have been solved by a reinstall of Vista

    Go to the website of the manufacturer of your computer/laptop > drivers and downloads Section > key in your model number > look for the latest Vista drivers > download/install them.

  • ultra computer window 7 not sometimes wake up after hibernation

    I am running windows 7 ultra on computer dell xps QuadCore 8300 and recently my computer sometimes wake up after hibernation when I move the mouse so I have to shut down the computer using the power button can you help me.

    Go to your control panel and go to your Power Options. No matter what plan you have selected, click on "Change plan settings", then click "change advanced settings of power."

    This should open a list of options, now click on the button '+' option of sleep and
    change the "Allow hybrid sleep" to "Off".

    Just a note, you can avoid only the computer from sleep mode hybrid, means the hard disk activity will remain intact. So the next time your windows is asleep, you can always get on easily by just moving the mouse or pressing a keyboard button.

    Please see the link below. And I believe that it is a desktop computer?

  • 2nd monitor doesn't Wakup after sleep

    After windows turns off my two screens, one of them wakes up when I move the mouse. The only way to get the screens, is to run a windows program that triggers a dialog box "User Access Control" (i.e. the Device Manager).
    I am running two 1920 x 1080 monitors on my Vista Home Premium computer via my Geforce 9200 card. A monitor is driven via HDMI and the other via a VGA cable. After 20 minutes based on my power settings, Windows disables the views.  When I started to work again through the mouse or keyboard, only the monitor connected via HDMI wakes up.
    I have the latest drivers from nVidia.
    Thanks in advance,
    -Jordan

    Hi, I realized that it was only afterwards that I had updated my Nvidia drivers. I downgraded back to an earlier version and no longer have the problem. Thanks for your help!

  • U2415, Nvidia GTX 950, monitor wake up after the deep sleep?

    I have two-desktop monitor. We're U2415, connected via mini - dp-> DP and the other is U2311H, connected via DVI on my Strix Nvidia Asus gtx950 video card.

    When starting PC, DVI monitor is always first & fastest even if it's my secondary monitor, but this isn't a problem.

    However, the real problem is when to wake up my PC after monitor deep sleep DP (30 minutes, several hours or more) won't wake up at all. It stays black. I have to manually, press the 'power' 2 times before monitor finally wake up and restoration of 2 desktop screen.

    Before NVIDIA, I got an AMD card and this was never a problem (although I used to connect to U2415 via HDMI). I used the tool to remove all previous video drivers. I'm also using the latest Nvidia drivers, 10 x 64 windows.

    I must point out that when you wake up to a short sleep mode, everything is fine. If I wake up monitors in less than 30 minutes, or so they work as should. I also activated 1.2 DP see if the problem will be solved.

    I am ready to suggestions, what I should check then in Windows, monitor settings etc. ?

    Thank you!

    Looks like the Nvidia driver is slow to launch the DP communication CDM from deep sleep causing the monitor to think that nothing is connected. You could try to test a DP to DP cable and see if the problem persists. One solution would be to connect in this way =
    NVIDIA GTX950 DVI out--> DVI to DVI cable--> DVI U2311H in
    NVIDIA GTX950 out HDMI--> HDMI to HDMI cable--> U2415 HDMI in
