Windows 10: HP 27ec Monitor Keeps Continuously Waking from Standby After Computer Sleeps Automatically

Hi I have an odd situation. When my laptop sleeps automatically after a period of inactivity, the HP 27ec monitor will enter standby mode, make the device connect/disconnect sound, then wake back up, enter standby mode again, and continue ad infinitum. The laptop does not do the same on another monitor, so the issue is isolated to the monitor. Also another laptop plugged into the same monitor doesn't have the same issue. And if the computer is slept manually the issue doesn't occur. The computer is an Acer Aspire E5-575G. Things I have tried:disable usb selective suspend and link state power m

Pc will not wake up from Standby

i would suggest you check how it is set to resume from standby, does your monitor automatically power off when the computer is turned off or do you have to press the power button on the monitor itself?

 

Continuous Device Connect/Disonnect Sound when HP W2207 Monitor Sleeps

Hope someone can help.

HP Pavilion p7-1287c Desktop PC with HP W2207 monitor, running Windows 10. DVI cable from monitor to PC.

Here's what's happening:

• If signed out of windows the monitor sleeps without issue.
• If signed on to windows the monitor sleeps and the computer loops the device connect/disconnect sound.
• If using VGA cable no issues with monitor sleeping but computer won't sleep.
• Have disconnected all USB devices except wireless mouse/keyboard combo.
• Have tested with wired USB mouse and keyboard same issue.
• Have ensured all drivers are updated to the latest versions.
• Have tried playing with the Advanced Power Option settings for USB and no change in behavior.
• Have tried requiring a password on wakeup and still no change.
• Would like to keep the DVI cable vs going back to VGA.

Please don't suggest turning off the sound for connecting/disconnecting devices.

Thanks.

Monitor will not wake from sleep

When my PC wakes from sleep it always used to wake the monitor as well but now when the PC wakes the monitor does not respond. The only way to solve the problem is to do a hard reset of the PC. The PC is definitely waking from sleep. it is just the monitor.

I have read multiple forums trying to find a solution but nothing seems to work. things I have tried:

• 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
  
• probably a few more that I have forgotten
