I have a very strange problem with a ZBook G1 17 and NVIDIA Quadro K610M in windows 7, 8 or 10.

I use SendMessage(mi.hwndMonitor, WM_SYSCOMMAND, SC_MONITORPOWER, (LPARAM)2); to turn off the display.

But often not works fine. It power off monitor, but when I press a key, the monitor power on but the screen remain black.

Then I have to suspend in ram the nb with power off button configured and power on to have monitor wake up.

This happens especially when:

  • Wake up before 90 seconds work fine.
  • Wake up after 90 seconds black screen. (but 1% success also)
  • Wake up after long tme but first at OS boot again black screen. I tried, But without success:
  • PauseResumeThreadList(2) - {win}{ctrl}{shift}b
  • Full Uninstall driver and reinstall last and old from HP and Nvidia
  • Replace Ram
  • Modify Windows power option
  • Update and Modify Bios option, ...

everything works 100% perfectly, the only stain is black monitor when use SC_MONITORPOWER.

I tryed also Nvidia support here.

Could you suggest me some way to solve this problem?

    Hi Diama,

    Thanks for your post. Generally speaking, you can try the following steps to narrow down the issue:

    • updating BIOS
    • restoring Windows
    • running Windows Update
    • trying a different monitor
    • checking monitor settings
    • turning off Fast Startup
    • Running Troubleshooter Power
    • turning off Link State Power Management
    • Restarting in Safe Mode
    • Updating and Rolling Back the display adaptor
    • checking that keyboard and mouse can wake the PC

    If these methods still don’t help, you can repair system file corruption by following steps:

    System File Checker (SFC) and Deployment Image Servicing and Management (DISM) scans can repair Windows system files and restore UI functionality.

    1. Open Task Manager with Ctrl + Shift + Esc.
    2. Click Run new task.
    3. Type cmd into the text box, check the box next to Create this task with administrative privileges and click OK.
    4. Click Yes when User Account Control asks for permission.
    5. In the Command Prompt window, type in the following command and hit Enter: sfc /scannow
    6. Once the scan is complete, use the following commands and press Enter after each: Dism /Online /Cleanup-Image /CheckHealth Dism /Online /Cleanup-Image /ScanHealth Dism /Online /Cleanup-Image /RestoreHealth
    7. (Note: if you get an error executing this last command, add /Source:C:\RepairSource\Windows /LimitAccess to it and try again).
    8. Restart your device.

    Best Regards,

    Ian Xue
