Symptômes

After not using your Bluetooth mouse or keyboard for some time, you may not be able to use the device again without rebooting the system or turning your Bluetooth radio off and back on.  This article applies to your symptoms if the following conditions are also true:

 

        1.     Your computer has a Broadcom-based Bluetooth radio.

        2.      Your Bluetooth radio has ?Allow the computer to turn off this device to save power? enabled.

 

You can check these settings by doing the following:

Windows 8:

1.  Select the Search charm and type ?Device Manager?. 

2.  Select "Settings".  "Device Manager" should be listed in the results.  Click on "Device Manager".

3. In Device Manager, expand "Bluetooth" and select the Bluetooth radio.  

4.  Right click on the Bluetooth radio and select Properties.

5.  On the Advanced tab, the Manufacturer Id will be 15 if your radio is Broadcom-based. 

6.  On the Power Management tab, ?Allow the computer to turn off this device to save power? is enabled if the checkbox is checked.

Cause

The Bluetooth Radio is not resuming from a low power state correctly.

Résolution

On the Advanced tab for the Properties of your Bluetooth radio, check the HCI and LMP versions. 

 

If these versions are 6.0 or higher, then update to the latest radio driver available by checking Windows Update. If there is no update available, check with the manufacturer of your PC using their support site.

To access Windows Update:

Windows 8: Select the Search charm and type ?Windows Update?. Select "Settings" and click on the "Windows Update" program icon.

Windows 7: Click the Start button and type "Windows Update". Click "Windows Update" from the Results window.

 

If the HCI and LMP versions are 5.x or lower, uncheck the checkbox for ?Allow the computer to turn off this device to save power?.
