Changing Bluetooth Power Management Settings

Changing Bluetooth Power Management Settings

If your mouse is disconnecting unexpectedly, failing to reconnect over Bluetooth, or a firmware update is stalling half-way on Windows. Adjusting your systems Bluetooth power saving settings as described below can help.
This Bluetooth power saving options was removed in Windows 10 build 2004, and all subsequent versions of Windows 10. However it has been restored in Windows 11. So if you have Windows 10 build 2004 or newer, refer to the note at the bottom of the article for a potential workaround.

Step 1 - Open Bluetooth Options

Open the Windows Bluetooth settings menu where you normally pair with your mouse. Under the related settings select select ‘ More Bluetooth options‘

 

Step 2 - Select your Bluetooth Adapter

Select the ‘Hardware’ tab. This will display all of your connected Bluetooth devices, along with your Bluetooth Adapter and some other system services.  

We need to find your Bluetooth adapter in the list. Depending on your device this can have a variety of different names. But in most cases it will include the words  Adapter,  Radio, or  Wireless. 
For example: 
  1. Generic Bluetooth Radio
  2. Intel wireless Bluetooth
  3. Realtek Bluetooth Adapter
  4. Marvell AVASTAR Bluetooth Radio Adapter
  5. Bluetooth USB module
Once you have found your adapter in the list, select it then click the Properties button.


Step 3 - Open its settings

 In the Properties window which opens click the ‘ Change settings‘ button in its bottom left corner.


Step 4 - Disable Power Management

This will open a new window almost identical to the previous one. Except it should have a new ‘ Power Management‘ tab on the right. Select this then un-check the box beside ‘ Allow the computer to turn off this device to save power’, and press ‘OK’.


In Windows 10 build 2004 and above the Power Management tab may not be available on your Bluetooth adapter from the location. So if you don't find it there instead check under the Human Interface Devices category of Device Manager for a Bluetooth Low Energy GATT compliant HID device, or something similar. This should have the power management tab that was missing from the other location.
