Many of you may have found it annoying that your bluetooth mouse goes to a "hibernation" state every time after a short idle time and you have to wake it up again. The delay it takes to wake it up drove me crazy. But here is the fix for this issue if you find it annoying. 1. Right click on the start button, select "Device Manager" 2. Find Bluetooth->"Marvell AVASTAR Bluetooth Radio Adapter" 3. Right click and select properties. 4. Go to power management tab and uncheck "Allow the computer to turn off this device to save power" Hope this helped!
