I have a Dell laptop, which is running on Windows Vista operating system. All features and functions were working very well to last date. But one of the features, the inbuilt Bluetooth is not functioning along with the newly acquired Nokia E51 mobile phone. When I attempted to connect the mobile phone to the laptop via Bluetooth, so it prompts me a message that the Bluetooth device is not detected, and after the second try I made the connection, but in this when I try to send a file so at that time connection drops. So regarding this if you guys have any solution so please help me as soon as it is possible for you guys.
