I am unable to enable bluetooth on this machine. When I right-click on Bluetooth Manager in the taskbar and select Enable Bluetooth Radio, I receive a message "Activate Bluetooth using Fn + F2 or the Radio ON/OFF switch. I tried Fn + F2 and there is no response from system. Please help. I just purchased a new Logitech bluetooth mouse and it is useless unless I can enable the bluetooth radio. Thanks.
