Windows 10 – Bluetooth mouse suddenly disconnects or stops working

If you have a Bluetooth mouse, you might face the issue that the mouse suddenly disconnects or stops working randomly. Here is a quick fix you can try to do to get rid of this issue.


If your Bluetooth mouse suddenly disconnects or stops working, this can indicate that Windows disconnects the PC's radio to save power. This issue is very common for laptop users where the operating system is tuned for maximum power saving, but it can affect desktop users as well. You need to make sure that your Bluetooth radio is not being turned off by the operating system's power management feature. Here is how it can be done.

  1. Connect your mouse to the computer, pair it and turn it on. Make sure it's working properly at least once.
  2. Right click the Start button to open its context menu (Power User menu, also known as Win+X menu). Select the item called "Device Manager". Windows 10 open device manager
  3. In Device Manager, expand the Bluetooth node. Windows 10 bluetooth
  4. Locate the Bluetooth radio you have. Double click the Bluetooth adapter to open its properties: Windows 10 bluetooth properties
  5. Switch to the Power Management tab and uncheck "Allow the computer to turn off this device to save power". Windows 10 bluetooth power saving

This should resolve the issue. This should be useful for any device - Bluetooth keyboard, headset, speaker, mice etc.

    You are an absolutely life-saver, sir. Thank you!

    This issue has been plaguing me throughout the past 3-4 Anniversary Update builds and your solution works wonders.

    This isn’t just a Windows 10 fix. I’ve been using Bluetooth mice (and other devices) since XP, and the setting to “turn off this device to save power” has been active by default for Bluetooth radios in every version of Windows since those days. Every time I get a new computer or reinstall Windows of any version, going into Device Manager to turn off that setting for the Bluetooth radio is always one of the first things I do.

      Yes it applies to Windows XP, Vista, 7 and 8.1 as well.

    This isn’t it. The windows 10 that I’m running (Build 16299) doesn’t not have the tab “power management”.

      It depends of drivers and your device’s supported power mode.

      Mine didnt either going through this way, i had to go into bluetooth settings in general settings, scroll down, click more bluetooth options, go to hardware, then click on your Bluetooth, properties, and then the change settings button at the bottom of the window with the “admin” shield next to it, then there should be the power management tab.

    This did not work. I run Windows 10 and I bought a logitech mouse M590. It was working perfectly fine, until a windows update started. Then my computer refused to accept that it had a bluetooth connection. I fixed it and it was running properly, until a day later that it just would detect the mouse any longer. I cannot fix it and I am pretty sure that it is a microsoft problem. I would not use Windows 10 if my new laptop did not come with it. I swear that after I resolve the problem I will disable any windows updates, because they just mess up systems and I lose a lot of working hours trying to troubleshoot and resolve things.

    WOW! I have a MacBook and made a partition for windows 10. My mouse kept disconnecting after 1-2 minutes and I couldn’t figure out why as all drivers were installed. This was the solution thank you!

    This worked great until Windows updated the Bluetooth driver. Now the “power management” tab is missing from my Bluetooth radio. Does anyone know how to get the tab back?

    So I went through those steps , unfortunately the power save box was already unchecked, does anyone have any other suggestion. it’s a fairly new keyboard and mouse, they will work for about 10 minutes then nothing, only way to fix it as of now is restarting the computer.
