Microsoft Bluetooth Mouse Fails to Reconnect

Hello Furkan,

This is April, I'll be happy to assist you. Sorry to hear that you're having issue with Microsoft Bluetooth Mouse. Let me help you out.

Based on your findings and from other sources, this issue appears to stem from Windows power management settings and Bluetooth service behavior, rather than a fault with the mouse adapter itself.

1. When the mouse fails to reconnect, does Windows still show it as "paired" and "connected" in Bluetooth settings or is it missing entirely?
2. Does the mouse reconnect automatically after waking from sleep if you leave Bluetooth on or does it only fail after toggling Bluetooth or restarting?
3. Have you checked Event Viewer for any Bluetooth or HID-related warnings or errors at the time of disconnection or failed reconnection?

Here are step-by-step fixes to try:

1. Disable Power Saving on the Bluetooth Adapter Windows may be disabling the Bluetooth radio to save power, which can interfere with automatic reconnection:
   • Open Device Manager
   • Expand Bluetooth, then right-click your Bluetooth adapter (e.g., Intel Wireless Bluetooth)
   • Select Properties > go to the Power Management tab
   • Uncheck "Allow the computer to turn off this device to save power"
   • Click OK
2. Change Bluetooth Support Service to Use the Local System Account This ensures the service has sufficient permissions to maintain device connectivity.
   • Press Win + R, type services.msc and press Enter
   • Locate Bluetooth Support Service
   • Right-click > Properties
   • Under the Log On tab, select Local System account
   • Apply the change and restart the service
3. Run Bluetooth and Power Troubleshooters These built-in tools can help detect misconfigured settings or driver issues.
   • Go to Settings > System > Troubleshoot > Other troubleshooters
   • Run both:
   • Bluetooth Troubleshooter
   • Power Troubleshooter
4. Update Bluetooth Drivers Even if the adapter works with other devices, oudated drivers can cause specific issue with certain peripherals.
   • Open Device Manager
   • Right-click your Bluetooth apdater > Update driver
   • Choose Search automatically for drivers
   • You can also check your PC manufacturer's website for the latest Bluetooth stack
5. Disable USB Selective Suspend (if using a USB Bluetooth dongle) This setting can interrupt Bluetooth communication on USB-connected adapters.
   • Go to Control Panel > Power Options
   • Click Change plan settings > Change advanced power settings
   • Expand USB settings > USB selective suspend setting
   • Set it to Disabled

Ubuntu's Bluetooth stack handles device reconnection more gracefully. It doesn't aggressively power down the Bluetooth radio or enforce strict sleep behavior like Windows does. Especially in newer versions like Windows 24H2/25H2, power-saving features can interfere with low-power peripherals like Bluetooth mice.

If the issue persists, consider using an external Bluetooth dongle with its own driver stack. These can sometimes bypass the quirks in Windows' handling of built-in Bluetooth radios.
