Hi,
First you will have to check if the blue tooth services is running. There
will be a special button on top of the keyboard on the laptop and one icon
will be in the shape of B. That is the bluetooth key. Hold the button down
for a while and you should get a message showing the status of bluetooth
(provided that you installled the software for the functionality of the
special keys).
Now you should have the blue light flashing on the laptop and that indicates
that the blue tooth is functioning. In some laptops there will be a switch at
the bottom of hte laptop. You will have to turn the laptop upside down to
access this.
Do post your queries if this still doesnt help you.
