bluetooth not working

[pol]

Hi all,

I cannot use the bluetooth device, that should be built-in in my hp tc4200
tablet laptop.
Nothing results as i ask for listing of Bluetooth devices:
    hcitool dev

Clicking on the kbluetooth applet yields: 'no working bluetooth adapter
found. Only local services will be displayed"


Any ideas?
Thank you for your help
