Fix: Bluetooth Mouse disconnects randomly in Windows

One of the common issues which users, including myself, face is that the Bluetooth mouse gets disconnected randomly. I did look around a bit on the Internet and in the computer’s settings and was finally able to solve the problem. Today I’ll share with the steps I took to fix the problem.

Bluetooth Mouse disconnects randomly

The first thing that came to my mind as always was to reinstall the Bluetooth drivers with the latest version available for my model, from the manufacture’s website. In my case it is Samsung. The best and clean way to update a driver, is to remove the drivers, first from the Device Manager then reinstall the new drivers. To do so:

  • Press Win + X and select Device Manager
  • There you’ll find Bluetooth Adaptor


  • I just right-clicked and clicked on Uninstall
  • Then I rebooted the system and installed the drivers, which I had downloaded from Samsung’s website.

Then I tested for a few hours, but the problem still persisted. So I looked around the Power Management settings, and decided to make a few changes.

  • Again, press Win + X and select Device Manager
  • There you’ll find Bluetooth Adaptor
  • Right-click and select Properties.


  • Then I unchecked “Allow the computer to turn off this device to save power”

Now I tested for few hours and found that I faced no problems so far. It’s been almost a week still no issues. So I can confirm that this resolution actually works.

Have a look at these posts too:

  1. Bluetooth is not working in Windows
  2. Bluetooth devices not showing or connecting

I hope you find this help. In case if you have an alternative troubleshooting steps, please do share it with us under the comments section.

    Great post… this has been a nagging thing for me since Win 7. The only power setting for Bluetooth was in Device Manager, under the Bluetooth adapter, the entry called “Bluetooth Radio”. I unchecked the box and now Bluetooth is working perfectly. Thanks!

    After having my laptop for six years, I just found that out about that six months ago. I have always thought that it was a Windows Vista/7/8 Bluetooth connectivity problem but, turned out to be the Power Management setting. The Bluetooth mouse is now dependable.

  • Scott

    Thanks for the tip

  • Gabriel

    Dude, you can do it simply, expand the bluetooth section, and right click select the Generic Bluetooth Adapter, And, uncheck the power saver option

  • wtf ms

    There’s no power management tab in the bluetooth adapter properties on my win8 (laptop i7), please help !

  • Anand Khanse

    Which OS are you using? Could you check if your Driver is up-to-date?

  • Vikram

    Works perfect…..

  • Justhelping

    Go to the Control Panel, Power management, select the option you are using, open the advanced settings, find USB sleep and disable both. My Bluetooth adapter is listed as USB.

  • Justhelping

    OOPS that’s Power Options in Control panel :)

    You are a genius! This has been bothering me for so long, I would use my mouse and then the second i stopped for a few seconds id have to click and move it around for a few seconds before it started up again. I know it doesnt sound like much of a hassle but when youre on the compuer for 8 hours it can happen a few hundred times.

    I did not have the “Power Managment” tab anywhere. I called Microsoft support and was finally able to get my Microsoft Arc Surface mouse from disconnecting by doing the following:
    1) Swipe from right side of the screen to get charms menu
    2) Search “Hyperv” and select the option “Turn windows features on or off”
    3) Locate the box next to the option “HyperV”
    4) Check the box for “HyperV”
    5) Check OK — computer will now restart
    6) Swipe from right side of screen to get charms menu
    7) Search “Device Manager” and select it
    8) Click the arrow in front of “Network Adapters”
    9) Find Marell AVASTAR Windows-AC Network Controller” and single click to select it
    10) Right click over “Marell AVASTAR Windows-AC Network Controller” and select “Properties.”
    11) You should now see a power management tab available — click on the tab
    12) Uncheck “allow the computer to turn off this device to save power.”
    13) Click OK.

    This worked for me. HyperV and this setting drop the battery life, but it’s relatively insignificant. Machine might also feel a bit “warmer” to the touch if you are working heavily on it.

    I had the same issue on win7 with non-admin account.
    I was able to see power management tab after logging in admin account.

  • Pep

    Nice! Thanks for posting. Worked for me!

  • JimiBlu

    Thanks! Unchecking the power option was the ticket for me! You are much smarter than all of the people at Lenovo Call Center in The Philippines.

  • Peter zemlany

    Hi Having the same problem with Bluetooth dropping out for whatever reason,will try your instructions and will let you know how i go

  • Garrett

    this solution does not work for me. I cannot find any “bluetooth settings” in my Device Manager. Win7

  • Pavlin Koev

    Great post! it worked for me. I have windows 7 professional,

    Thank you!

  • Brad

    Trying the above did not work for me. But then the most obvious did: changing the batteries.

    My HP x4000b uses AA batteries, and after about 6 mos of heavy use, changing the batteries was the simple step that finally fixed the very frustrating problem of the bluetooth mouse sporadically losing its wireless connection.

  • Brad

    Same with me, but then I changed the (AA) batteries in the mouse. And that did the trick.

  • Jakob

    I already had the box unchecked but it still nagging me to this day. I’ve had it like this for almost half a year now!

    Got it on febuary(2015).

  • Nelson Bibby

    Thanks this helped me out greatly.

  • Jac

    THANK YOU! I just started a new job and my new computer kept turning off my mouse. I work from home and without support this was driving me crazy. Nick, you’re a lifesaver. You deserve a cape and a sidekick.

  • Nishant Thakur

    Thanks! It was a life saver. Now my bluetooth headphones are working perfectly.

  • anon

    Don’t hate on call centers. They’re given a data base to search. They’re just doing their jobs. I’m glad Lenovo offers jobs to people in the Phils. You have no idea how rough some of the poorer areas are.

  • Amir Delju

    Dear Shyam. Congratulations! I followed your advice and solved the problem with my new bought bluetooth mouse. Thanks for sharing your valuable experience.
