HP Omen 40L wakes up from sleep but disables all USB ports and monitors

[ZW6]

HI, I just bought an HP OMEN 40L Gaming Desktop GT21-1355st, but whenever it wakes up from sleep, the monitor screen, all the USB ports (keyboard of course), and bluetooth mouse stop working. I have to turn the power off and on to be able to use the computer.

I have tried EVERYTHING (I mean it), all drivers, bios, windows, you name it all up to date. I meddled with POWER, DEVICE settings etc. nothing would sold this.

Hi @ZW6,

Welcome to The HP Support Community.  

Thank you for posting your query, I will be glad to help you.

I understand you are facing an issue issues with a new system, especially after ensuring all drivers and software are up to date. Here are several steps you can try to troubleshoot and potentially resolve the issue:

1. Check Power Settings in Device Manager

USB Root Hub:

1. Open Device Manager (Press Win + X, then select Device Manager).
2. Expand the "Universal Serial Bus controllers" section.
3. Right-click each USB Root Hub and select "Properties".
4. Go to the "Power Management" tab.
5. Uncheck "Allow the computer to turn off this device to save power".

Network Adapters:

1. In Device Manager, expand the "Network adapters" section.
2. Right-click your network adapter and select "Properties".
3. Go to the "Power Management" tab.
4. Uncheck "Allow the computer to turn off this device to save power".

2. Disable Fast Startup

• Open Control Panel.
• Go to "Power Options".
• Click "Choose what the power buttons do" on the left.
• Click "Change settings that are currently unavailable".
• Uncheck "Turn on fast startup (recommended)".
• Click "Save changes".

3. Adjust Power Plan Settings

• Open Control Panel.
• Go to "Power Options".
• Click "Change plan settings" next to your selected plan.
• Click "Change advanced power settings".
• Expand the "USB settings" and then "USB selective suspend setting".
• Set it to "Disabled".

4. BIOS Settings

• Reboot your computer and enter the BIOS setup (usually by pressing F2, F10, Delete, or Esc during startup).
• Look for power management settings related to USB and sleep states (S3, S4, S5).
• Ensure that USB wake support is enabled.

5. Update or Rollback Drivers

• Even if you have updated all drivers, sometimes a specific version might cause issues.
• Consider rolling back to a previous driver version for your chipset and USB controllers.
• Alternatively, you can use the HP Support Assistant to ensure you have the recommended drivers for your specific model.

6. Check for System Firmware Updates Update the firmware on an HP printer

• Ensure that your system firmware (BIOS/UEFI) is up to date.
• You mentioned updating the BIOS, but double-check on HP's support site for the latest version and any related instructions.

7. Disable Hybrid Sleep

• Open Control Panel.
• Go to "Power Options".
• Click "Change plan settings" next to your selected plan.
• Click "Change advanced power settings".
• Expand the "Sleep" section.
• Set "Allow hybrid sleep" to "Off".

8. Check Windows Event Viewer

• Open Event Viewer (Press Win + X, then select Event Viewer).
• Look for critical errors or warnings in the "System" and "Application" logs around the time you wake up the computer.
• This might give clues about what is causing the issue.
