    Since the keyboard works, Bluetooth itself is fine on your PC. The problem is the mouse’s pairing or its connection to Windows. Try these in order:

    Replace or recharge the mouse batteries.

    Check the mouse’s power switch and make sure the Bluetooth LED is on.

    Move the mouse within a meter or so of the PC and away from USB 3.0 hubs or Wi-Fi routers, which can interfere with Bluetooth.

    Go to Settings → Bluetooth & devices → Devices.

    Find the mouse, click the ⋯ menu and choose Remove device.

    Put the mouse into pairing mode (usually hold the Bluetooth/connect button on the underside for 3-5 seconds until the LED blinks).

    Click Add device → Bluetooth and select the mouse when it appears.

    Removing the old entry matters. A stale pairing record often blocks reconnection, especially after a Windows update or if the mouse was paired to another device.

    Press Win + R, type services.msc and press Enter.

    Find Bluetooth Support Service, right-click it and choose Restart. Confirm its startup type is Automatic.

    Settings → System → Troubleshoot → Other troubleshooters → Bluetooth → Run.

    In Device Manager, expand Bluetooth, right-click your adapter and choose Update driver. If the mouse appears under Human Interface Devices or Mice with a warning icon, uninstall it there, then re-pair.

    Remove the mouse from Windows, put it into pairing mode, and add it again; the working keyboard indicates that troubleshooting should begin with the mouse-specific connection rather than the entire Bluetooth radio.

    Re-pair the mouse

    1. Check or replace the mouse batteries. For a rechargeable model, charge it using its supplied USB cable.
    2. Open Start → Settings → Bluetooth & devices → Devices.
    3. Find the Microsoft mouse, select More options (⋮) → Remove device → Yes.
    4. Press and hold the pairing button on the bottom of the mouse for 5–7 seconds. Release it when the light begins blinking.
    5. In Settings → Bluetooth & devices, select Add device → Bluetooth.
    6. Select the mouse and complete the prompts. ^1^

    If the pairing light flashes three times and turns off, the mouse is already paired with another nearby computer. Remove the mouse from that computer’s Bluetooth device list, and then repeat the steps above. ^1^

    If the mouse does not appear

    On Windows 11:

    1. Open Settings → Bluetooth & devices → Devices.
    2. Under Device settings, change Bluetooth devices discovery from Default to Advanced.
    3. Put the mouse into pairing mode again and select Add device → Bluetooth. ^2^

    Also try these isolation checks:

    • Temporarily turn off other Bluetooth devices, including the keyboard, and pair the mouse again. Multiple connected devices can interfere with pairing.
    • Keep the mouse near the PC and away from unshielded USB devices connected to USB 3.0 ports.
    • Test the mouse with another PC. If it also fails there—especially if its pairing light does not illuminate after installing fresh batteries—the mouse may need replacement. ^1^ ^3^

    If it works on another PC

    Run the Windows Bluetooth troubleshooter:

    • Windows 11: Open the Get Help app and run the Bluetooth troubleshooter.
    • Alternatively, open Settings → System → Troubleshoot → Other troubleshooters → Bluetooth → Run.

    If that does not resolve it:

    1. Open Device Manager → Bluetooth.
    2. Right-click the Bluetooth adapter—not the mouse—and select Update driver → Search automatically for drivers.
    3. If Windows finds nothing, install the latest Bluetooth driver provided for the exact PC model by its manufacturer.
    4. Restart Windows and pair the mouse again. ^2^

    As a final driver-repair step, uninstalling the Bluetooth adapter affects all Bluetooth devices temporarily:

    1. In Device Manager → Bluetooth, right-click the Bluetooth adapter.
    2. Select Uninstall device → Uninstall.
    3. Shut down the PC, wait several seconds, and turn it on. Windows should reinstall the adapter.
    4. If it does not, select Device Manager → Action → Scan for hardware changes. ^2^
