If your mouse stops working after your system has been inactive or wakes up from sleep, try modifying your Bluetooth adapter's power settings.

1. Launch Control Panel > System and Security > System > Device Manager.

2. Under Bluetooth Radios, right-click your Bluetooth adapter (ex. Dell Wireless 370 adapter), and click Properties.

   

3. In the Properties window, select the "Power Management" tab, and clear this check box: "Allow the computer to turn off this device to save power".

   

4. Click OK and then reboot the PC.

If this solution doesn't work, restart your computer and try again.
