A Windows 7 or Vista-based computer may go to sleep during a Bluetooth file transfer
Article ID: 937827 - View products that this article applies to.
When you transfer a large file between two Windows 7 or 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.
To work around this problem, verify that the computers are not configured to go to sleep after a short time. For example, if you expect to perform Bluetooth file transfers of files that may take 30 minutes or so to complete, configure the computers to go to sleep after 60 minutes of inactivity.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
