I got a new Bluetooth mouse and it was always losing connection (not working) when my sp3 awoke from sleep. I was about to return the *#&^% thing and get another one from Amazon when I read about a fix in one of Amazon's comments. Seems Windows defaults to controlling the shutoff of Bluetooth whenever it thinks it should. What does it know? * Search for Device Manager * Open the 'Bluetooth' category. * Double click on "Marvell AVASTAR Bluetooth Radio Adapter". * In the new window that comes up, click on the "Power Management" tab. * Uncheck the "Allow the computer to turn off this device to save power". Mouse works like a charm! Note this may improve connection problems (especially after sleeping) with all your Bluetooth devices.
