Allow bluetooth devices to wake PC

Enable device Wake-on-Bluetooth

• Connect the Bluetooth device
• Run Device Manager
• Double-click Bluetooth
• Double-click the specific device (not the Bluetooth adapter!)
• Click the "Power Management" tab
• Click to check "Allow this device to wake the computer"
• Click OK
• Reboot.

If the device doesn't have a "Power Management" tab, perhaps the following can still help.

Disable hibernate

In general, the Bluetooth device will be disconnected when the system enters sleep or hibernate mode, so cannot wake up the computer.

However, if Modern Standby is supported, the Bluetooth devices are still connected after the system enters sleep mode. But if it enters hibernate mode, the connection will be disabled.

Here is how to enable Modern Standby:

• In the Start menu, run "Choose a power plan"
• Click "Change plan settings" for your power plan
• Click "Change advanced power settings"
• Expand "Hibernate after", located under "Sleep"
• Set "On battery" and "Plugged in" as "Never"
• Click OK
• Reboot.

If this doesn't work still, the chances are slim, but continue on.

Last-ditch effort

• Run Command Prompt (cmd) as Administrator

• Enter the command: powercfg /devicequery wake_programmable

• If you see the Bluetooth device in the list, run

    powercfg /deviceenableawake "Bluetooth Device exact name"
  

  Note: The above command is worded according to the documentation with deviceenableawake. However, the help shown by powercfg /? says rather that the verb is deviceenablewake:

   powercfg /deviceenablewake "Bluetooth Device exact name"
  

• Run the command:

    powercfg -devicequery wake_armed
  

  If your device is now in the list, this should now work. Reboot.

If nothing works, then the computer hardware probably does not support Wake-on-Bluetooth.
