Stop USB Mouse and Network Card Waking Windows 11

Windows 11 computers often wake unexpectedly from sleep mode due to sensitive peripheral hardware or network activity. This guide explains how to disable wake permissions for both USB mice and network adapters using the Windows Device Manager and Command Prompt, ensuring your PC stays in sleep mode until you manually wake it.

Prevent a USB Mouse from Waking Windows 11

  1. Right-click the Start button and select Device Manager.
  2. Expand the Mice and other pointing devices category.
  3. Right-click your connected USB mouse and select Properties.
  4. Click the Power Management tab.
  5. Uncheck the box next to Allow this device to wake the computer.
  6. Click OK to save the changes.

Note: If your mouse is listed under Human Interface Devices (HID), check that section as well if the Power Management tab is missing in the primary category.

Prevent a Network Card from Waking Windows 11

  1. Open Device Manager by pressing Win + X and selecting it from the menu.
  2. Expand the Network adapters category.
  3. Right-click your active network card (Ethernet or Wi-Fi adapter) and choose Properties.
  4. Switch to the Power Management tab.
  5. Uncheck Allow this device to wake the computer.
    • Alternative: If you require Wake-on-LAN (WoL), leave the option checked but enable Only allow a magic packet to wake the computer to prevent general network traffic from waking the system.
  6. Click OK to apply the configuration.

Verify Devices Allowed to Wake Your Computer

To confirm that the mouse and network adapter can no longer wake the system:

  1. Press Win + R, type cmd, and press Enter.

  2. Type the following command and press Enter:

    powercfg -devicequery wake_armed

  3. Check the returned list. If configured correctly, neither your mouse nor your network adapter will appear.

To identify what woke your PC most recently, run:

powercfg -lastwake
