The NVIDIA USB Type-C Port Policy Controller frequently prevents HP Omen 15 laptops from entering sleep mode on Windows 10 by allowing the device to wake the system unexpectedly. You can resolve this issue by disabling the wake capability in Device Manager or adjusting advanced power settings to block wake timers, ensuring your laptop stays asleep when closed.
Identifying the Wake Source
Before applying fixes, it is essential to confirm that the NVIDIA controller is indeed the culprit. Windows provides a diagnostic command-line tool that reveals exactly which hardware event triggered the last wake-up. Open the Command Prompt as an administrator and type
powercfg -lastwake. This command returns the name of the device that woke the computer from sleep. If the output explicitly lists "NVIDIA USB Type-C Port Policy Controller" or similar USB-related entries, you have confirmed the source of the problem.
This diagnostic step is crucial because other peripherals like mice, keyboards, or network adapters can also cause unexpected wake-ups. By isolating the specific device, you avoid unnecessary changes to other system components. If the command does not return the expected result, check the Event Viewer under Applications and Services Logs > Microsoft > Windows > Power-Troubleshooter for detailed logs regarding recent sleep failures.
Disabling Wake Capability in Device Manager
The most direct solution involves modifying the properties of the offending device within Windows Device Manager. This setting tells the operating system to ignore signals from this specific hardware component when the system is in a low-power state.
Follow these steps to disable the wake feature:
- Right-click the Start button and select Device Manager from the context menu.
- Expand the System devices category by clicking the arrow next to it.
- Locate NVIDIA USB Type-C Port Policy Controller in the list. It may appear multiple times if you have multiple USB-C ports.
- Right-click the entry and select Properties.
- Navigate to the Power Management tab.
- Uncheck the box that says Allow this device to wake the computer.
- Click OK to save the changes.
Repeat this process for every instance of the NVIDIA USB Type-C Port Policy Controller listed in the System devices section. After making these changes, test the sleep function by closing the laptop lid or selecting Sleep from the Start menu. The laptop should now remain asleep until you press a key or open the lid.
Adjusting Advanced Power Settings
If the Device Manager fix does not fully resolve the issue, or if you prefer a broader system-level approach, you can modify the advanced power plan settings. Windows allows administrators to control how the system handles wake timers and USB selective suspend settings.
Access these settings by navigating to
Control Panel >
Hardware and Sound >
Power Options. Click
Change plan settings next to your active power plan, then select
Change advanced power settings. In the dialog box that appears, expand the
USB settings node and then
USB selective suspend setting. Change this setting to
Disabled for both On Battery and Plugged In states. While this might slightly increase power consumption during use, it prevents the USB subsystem from entering a deep sleep state that can conflict with the NVIDIA controller.
Additionally, ensure that
Allow wake timers under
Sleep is set to
Disable. This prevents scheduled tasks or updates from waking your computer unexpectedly, which often coincides with hardware wake issues.
Updating Drivers and BIOS
Outdated drivers can sometimes cause communication errors between the NVIDIA controller and the Windows power management system. Visit the official HP support website for the Omen 15 model and download the latest chipset and USB controllers drivers. Simultaneously, check for BIOS updates from HP, as these often contain fixes for power management logic specific to the motherboard's USB architecture.
Installing these updates ensures that the hardware interfaces correctly with Windows 10’s modern standby features. After updating, restart your computer and retest the sleep functionality. If the issue persists, consider rolling back to a previous stable version of the driver if the update introduced new instability.

Frequently Asked Questions
Why does my PC wake up randomly even after disabling the NVIDIA controller?
Other devices such as network adapters or mice may still be configured to wake the system. Check the Power Management tab for all USB and Network adapters in Device Manager to ensure their wake capabilities are also disabled.
Can I use the NVIDIA Control Panel to fix this sleep issue?
No, the NVIDIA Control Panel primarily manages graphics performance and display settings. It does not have controls for USB port policy or Windows power management interactions.
Will disabling the NVIDIA USB controller affect my external monitors?
No, disabling the wake capability only prevents the controller from signaling the system to exit sleep mode. Your external monitors will continue to function normally when you manually wake the computer.
What if the Power Management tab is missing in Device Manager?
This usually indicates outdated or generic drivers. Update your chipset drivers from the HP support page or reinstall the NVIDIA USB drivers to restore the proper device properties and power options.
Does Windows 11 handle this issue differently than Windows 10?
Windows 11 has more aggressive modern standby features which can sometimes exacerbate wake issues. However, the fundamental method of disabling the device in Device Manager remains the same and effective across both versions.
