Make sure your computer has the necessary hardware and that wireless is turned on. Bluetooth requires both hardware and software to work. Not all wireless networking hardware supports Bluetooth. Visit http://shopap.lenovo.com/ to check product specifications to see if the device is Bluetooth capable.

If the device has no built-in Bluetooth hardware, you may need to purchase a Bluetooth USB dongle.

Step 1: Enable Bluetooth radio

If Bluetooth is not turned on it may not show up in Control Panel or Device Manager. Enable the Bluetooth radio first.

Press the key or button to enable the wireless adapter. This key may be F8 or Fn+F5 (or F5).
