Wireless technologies such as Bluetooth and Wi-Fi can streamline infrastructure and make completing work-related tasks outside the office more convenient for business professionals. Some Lenovo ThinkPads include a Bluetooth card that enables the computer to pick up or broadcast Bluetooth signals over short distances. To protect your computer from intruders, you should turn off Bluetooth when you are not using it, but you can easily re-enable the wireless technology in just a few steps.
Press "Fn-F5" to open the Wireless Radio dialog box.
Click the "Power On" or "Radio On" option, located to the right of the Bluetooth Radio setting.
Click "Start | Control Panel | Hardware and Sound | Device Manager." Double-click "Bluetooth Radios."
Right-click device driver and select "Enable" from the context menu, if available.
Some Lenovo ThinkPads include a Bluetooth button, located next to the Bluetooth indicator light or embedded in the hinge or LCD cover.
