In my laptop (modelno:PSC2UG-00P001 toshiba) inbuilt bluetooth is not working. It is able to detect and search other bluetooth devices, but it is not able to send or receive any data ie my information exchanger is not working. How can I solve this issue. Please please help me..

Have you tried to pair the devices (such as a headset) with the laptop? When you go into the laptop's bluetooth admin tool to pair the device, what do you use for the device's password (4 digits usually - many default to 0000)? If 0000 doesn't work, you may need to look at the device documentation for the password required to pair it to your laptop.
