The Bluetooth notebook adapter makes short-range radio connections to a wireless Personal Area Network (PAN) and can access other Bluetooth-compatible devices, such as other computers, cell phones, audio headsets, a mouse, and printers.
Since the Bluetooth function connects the computer by radio rather than through cables, the devices can be moved around and remain connected to the computer. Bluetooth devices can automatically connect to the computer when they enter the computer's service area. The typical service area for computers or cell phones is about 30 feet (9 meters); however, it is only about 3 feet (1 meter) for a headset or keyboard.
If you move out of the reception area for the headset or turn it off, an error message may display:
Figure : Error message
If such an error message occurs, go through the startup and connection again.
Some, but not all, HP notebooks are sold with built-in Bluetooth wireless capabilities. The Product Specification documents that came with the computer specify if your computer does or does not have a Bluetooth device. The HP Wireless Assistant can also be used to verify the device is installed and enabled because it only lists wireless devices that are installed on the computer.
