A Bluetooth mouse won’t reconnect after sleep in Windows 11 usually because Windows cut power to the Bluetooth adapter or the USB receiver to save energy. The fix people report most is to clear “Allow the computer to turn off this device to save power” in Device Manager, on the Bluetooth adapter first. If that doesn’t work, turn off USB selective suspend, update the driver, or remove the mouse and pair it again.
This keeps showing up. Two separate threads on Microsoft’s Windows 11 community in June 2026 describe paired mice and keyboards that often don’t reconnect on their own after waking, forcing people to remove and re-pair them. A Windows 11 forum poster with a Cherry Bluetooth mouse on a Lenovo laptop reported disconnects after waking from standby or hibernate. We haven’t tested any of these fixes ourselves, so treat them as what users and guides report.
Two Problems That Look the Same
People mix up two different issues, and the fixes differ:
| What happens | Likely cause | Where to look |
|---|---|---|
| The mouse is paired but doesn’t reconnect after sleep | Windows powered off the Bluetooth adapter, or a driver glitch | Fixes 1, 2 and 5 |
| The mouse or keyboard won’t wake the PC at all | USB power is cut during sleep, or wake is turned off | Fixes 3 and 4 |
| The mouse reconnects after you click it | The mouse’s own sleep timer, which can be normal | See “What May Be Normal” below |

Did the October 2026 Update Fix It?
Possibly not. Windows Central reports that Microsoft’s October 2026 update for Windows 11 (KB5127648, released October 13, 2026) made eight Bluetooth changes. They include better connection status reporting for disconnected accessories, a fix for the radio turning off while the Settings toggle still showed on, and improved reliability for LE Audio accessories. The article does not mention sleep or wake reconnects. We couldn’t open Microsoft’s own release notes, so check them before relying on this.
It’s still worth installing the update, since it fixes other Bluetooth bugs. Go to Settings > Windows Update and install anything waiting, then use the steps below if the mouse still drops after sleep.
Fix 1: Stop Windows Turning Off the Bluetooth Adapter
Geekrewind’s Windows 11 guide (October 10, 2026) gives these steps:
- Right-click Start and open Device Manager.
- Expand Bluetooth and double-click your adapter, not a paired device.
- Open the Power Management tab.
- Clear Allow the computer to turn off this device to save power.
- Select OK. If devices stay disconnected, disable and re-enable the adapter, or restart the PC.
The guide’s caveats: you need administrator rights, and if the box is grayed out you’re probably on a standard account. If the Power Management tab is missing, install the manufacturer’s Bluetooth driver for your PC model. Turning this off costs a little battery life. It also notes that driver reinstalls or feature updates can restore the default, and manufacturer power utilities can turn it back on.
Fix 2: Do the Same for the Mouse Itself
The Windows Club’s guide says to open Device Manager, expand Human Interface Devices, right-click your Bluetooth keyboard or mouse, open Properties, and clear the same power-saving box on the Power Management tab. It warns the device’s battery will drain faster. One caution: a poster on Microsoft’s Q&A site said the Power Management tab was missing for their Bluetooth mouse and “nothing works,” so this isn’t available on every setup.
Fix 3: Turn Off USB Selective Suspend (USB Receiver Mice)
If your mouse uses a USB receiver instead of Bluetooth, Windows may suspend the port during sleep. In a June 2026 Microsoft community thread, a member suggested:
- Open Control Panel > Power Options > Change plan settings > Change advanced power settings.
- Under USB settings, open USB selective suspend setting and set it to Disabled for both “On battery” and “Plugged in.”
- If that doesn’t help, in Device Manager open each USB Root Hub under Universal Serial Bus controllers and clear the power-saving box on its Power Management tab.
Geekrewind adds that the root hub change affects other USB devices on those ports and uses more power on laptops, and that selective suspend changes only apply to the power plan you edit. Nobody in the June thread reported whether it worked.
Fix 4: Check the Laptop Power Recommendation
On Microsoft’s Q&A site, the accepted answer (2023) in a thread about keyboards and mice that won’t wake a PC pointed to a Windows 11 energy setting called “Stop USB devices when my screen is off to save battery,” which it said to turn off. The answer got hundreds of helpful votes, and another poster said it worked on Windows 11. A third poster said their desktop had no such option, since it has no battery. Setting names vary by version and language, so look in Settings > System > Power & battery.
Fix 5: Update the Driver, Run the Troubleshooter, or Re-Pair
- Update the Bluetooth driver from your PC maker’s site, as the Windows Club and Geekrewind both suggest.
- Run the Bluetooth troubleshooter. The Cherry mouse poster on the Windows 11 forum said it sometimes fixes the problem but not reliably, and sometimes needs several tries.
- Remove and re-pair. This is what the June 2026 posters were forced to do. It works, but it’s a workaround, not a fix. Our laptop pairing guide walks through a clean re-pair, and the steps apply to mice too.
- Test the mouse on another PC. The Windows Club suggests this to rule out a hardware fault.
What May Be Normal
Geekrewind notes that putting the PC to sleep disconnects Bluetooth regardless of the power setting, and that mice and other devices often have their own auto power-off timers. If your mouse reconnects after one click or button press, that may be normal behavior and not a bug. It’s only a problem if you must open Settings and re-pair it.
Same Windows Bluetooth Stack, Other Devices
The Bluetooth settings above also affect earbuds on your PC. If your earbuds drop or sound thin on calls, see our guide to Bluetooth earbuds that sound bad on calls, and if sound lags behind video, read Bluetooth earbuds out of sync with video.

Frequently Asked Questions
Why does my Bluetooth mouse disconnect after sleep in Windows 11? Windows can turn off power to the Bluetooth adapter or USB receiver to save energy. When the PC wakes, the device may not reconnect. Clear the power-saving option in Device Manager to stop this.
How do I stop Windows 11 turning off my Bluetooth adapter? Open Device Manager, expand Bluetooth, double-click your adapter, and clear “Allow the computer to turn off this device to save power” on the Power Management tab. You need administrator rights.
Why won’t my mouse wake my PC from sleep? Windows may cut USB power during sleep, or the wake option may be off. Try turning off USB selective suspend or the “Stop USB devices when my screen is off” setting.
Did the October 2026 Windows 11 update fix Bluetooth problems? It made eight Bluetooth changes, according to Windows Central, but the reported list doesn’t mention sleep reconnects. Install it anyway and use the fixes above if the problem continues.
Is it normal for a Bluetooth mouse to need a click after sleep? Often, yes. Some mice have their own sleep timers and reconnect after a click. It’s a problem only if you have to re-pair the mouse.
