When you transfer a large file between two Windows Vista-based computers by using a Bluetooth connection, one of the computers may go to sleep during the transfer. When this problem occurs, the file transfer is not completed.

This problem occurs if the file transfer requires more time than the time that is configured for the computer to go to sleep. For example, this problem occurs if you configure the computer to go to sleep after two minutes, and the Bluetooth file transfer requires three minutes to finish.
