How To Resolve Bluetooth Mouse Disconnections in Windows 11

Bluetooth mice are super convenient, especially compared to wired setups — no annoying cords, can connect from pretty far away, and work seamlessly across multiple devices. But of course, Windows 11 isn’t exactly perfect about keeping that connection stable all the time. Many folks notice their Bluetooth mouse disconnects randomly, sometimes pretty frequently, and that’s beyond frustrating. It’s kind of a mixed bag. Sometimes it’s driver issues, other times power management settings or even just flaky Bluetooth support. Usually, these problems aren’t huge but can be a real pain in the neck if they keep happening.

The key is to troubleshoot systematically. Most of the time, fixing these disconnects involves resetting drivers, tweaking some power options, or updating Windows itself. A lot of people find that one of these steps clears up the issue — or at least reduces its frequency. Since Bluetooth troubleshooting in Windows 11 isn’t always straightforward, here’s a rundown of methods that tend to help with persistent disconnects. Just keep in mind, some fixes might work on one machine but not another — Windows is weird that way, and so is hardware.

How to Fix Bluetooth Mouse Keeps Disconnecting in Windows 11

Check if a simple restart helps

Yeah, it sounds basic but restarting your PC clears out bugs or glitches that pile up over time — especially if your Bluetooth stack is acting weird. Sometimes, Windows just gets a little overwhelmed or confused, and a reboot can reset everything. After reboot, test the mouse for a bit. If it’s still disconnecting, move on to the more involved fixes below. Not sure why it works sometimes, but on some setups, a reboot actually fixes the problem temporarily — maybe Windows needs a fresh start, who knows.

Reinstall your Bluetooth mouse drivers

This is a classic. Corrupted or outdated drivers are often the culprits. Reinstalling gets rid of the bad files and replaces them with fresh, hopefully working ones. To do it:

Press Windows + X and select Device Manager
Expand Mice and other pointing devices.(Sometimes it’s hidden under Bluetooth adapters if your mouse is Bluetooth)
Right-click your Bluetooth mouse, then choose Uninstall device. Confirm if prompted.
After uninstalling, restart your PC. Windows will attempt to reinstall the driver automatically, but if not, you might need to manually download the latest driver from the manufacturer’s website, especially if it’s a specific model like Logitech or Microsoft.
Once Windows boots back up, reconnect the mouse and see if it disconnects again. Seems like a lot of people find that doing this clears up random disconnects temporarily or even permanently.

Update your mouse drivers

If reinstalling didn’t help, maybe your driver is just woefully outdated. Updating drivers ensures compatibility and fixes bugs that might cause disconnects. To update:

Open Device Manager again (Windowssearch for it).
Double-click Mice and other pointing devices.
Right-click your Bluetooth mouse, then select Update driver.
Choose Search automatically for drivers. Windows will look online for the latest updates. If it finds something, install it.
Reboot once it’s done and test again. Sometimes, this alone solves the problem if the driver was causing the disconnects.

Disable Windows Power Management for Bluetooth

Windows tries to save power by turning off Bluetooth devices when they’re not actively used — but that can backfire. You might see your mouse disconnecting because Windows is being too aggressive. To fix that:

Right-click the Start icon and go to Device Manager.
Expand Mice and other pointing devices.
Right-click your Bluetooth mouse, then pick Properties.
Go to the Power Management tab.(If you don’t see it, make sure you’re selecting the correct device, possibly under Bluetooth adapters in some cases).
Uncheck Allow the computer to turn off this device to save power.
Click OK and restart your PC. This prevents Windows from turning off Bluetooth unexpectedly when it thinks you don’t need it.

Update Windows to the latest version

Sometimes, the root cause is Windows itself — missing updates can cause overall Bluetooth messiness. Check for updates:

Open Settings from the Start menu.
Go to Windows Update in the sidebar.
Click Check for updates. Install any pending updates.
Reboot after all updates are installed and test again. Many bugs related to hardware support get patched in these updates, so keeping Windows current is crucial.

Run the Bluetooth Troubleshooter

Windows has a built-in troubleshooter that can quickly identify and fix common Bluetooth issues. Here’s how:

Press Windows + I to open Settings.
Navigate to System, then Troubleshoot.
Choose Other troubleshooters.
Find Bluetooth and click Run.
Follow the prompts; it might suggest fixes or just point out what’s wrong.

Make sure the Bluetooth Support Service is set to automatic

This service manages the Bluetooth device connection in Windows. If it’s disabled or set to manual, Bluetooth might behave poorly. To set it to automatic:

Right-click the Windows icon, then select Run.
Type services.msc and hit Enter.
Scroll to find Bluetooth Support Service.
Right-click, choose Properties.
In the Startup type dropdown, pick Automatic.
Click Apply and OK, then restart your PC. This often helps keep Bluetooth stable in the background.

Replace the batteries — yeah, really

Sometimes, it’s that simple — dead or weak batteries cause disconnects. Especially with wireless mice, low power causes connection drops, so swap in fresh batteries and try again. Happens more than you’d think; forgot to check this because of course, Windows has to make it harder than necessary sometimes.

Conclusion

All these fixes are some of the most common and usually effective ways to fix annoying Bluetooth disconnects in Windows 11. It’s a bit of trial and error sometimes — what works on one PC may not on another, but generally, reloading drivers, changing power settings, and keeping Windows up to date do the trick. If nothing works, it might be the mouse itself — try it on another device, and if it keeps disconnecting, time to replace it.

Summary

Restart your PC to clear glitches.
Reinstall or update your Bluetooth mouse drivers.
Disable Windows power-saving for Bluetooth devices.
Update Windows to the latest version.
Run the Bluetooth troubleshooter.
Set the Bluetooth Support Service to automatic.
Check or replace batteries in your mouse.

Wrap-up

This is a pretty solid list of steps that solve the majority of Bluetooth disconnecting issues. Sometimes, it’s just a matter of one fix and you’re back to flicking through your desktop smoothly. If not, dealing with hardware problems is next in line. Hopefully, this shaves off a few hours for someone. Fingers crossed this helps!
