Consider the following scenario:

• You install a Bluetooth device on a Windows Vista-based computer, and then you turn the device on.
• You put the computer into standby (the S3 power state) or into hibernation (the S4 power state).
• You resume the computer from standby or from hibernation.

In this scenario, the Bluetooth device no longer works . Additionally, a yellow exclamation mark (!) appears next to the device in Device Manager. When you view the device properties, the device status is reported as code 43.
