Dancer.exe Application Prevents Your Computer from Entering Standby or Hibernate
| Article ID | : | 822765 |
| Last Review | : | February 12, 2007 |
| Revision | : | 1.6 |
SYMPTOMS
When the Dancer.exe application that is included with Plus! Digital Media Edition is active, your computer cannot enter
Standby or
Hibernate as specified in
Power Options in Control Panel. You can manually put your computer in
Hibernate by using the
Shut Down
option on the
Start menu.

CAUSE
Microsoft Plus! Dancer monitors a particular audio line on the
recording mixer device to do music detection. Plus! Dancer monitors this audio line so that it knows when to start dancing and when to stop dancing when the application is configured to
Dance Only When Music Plays. This detection on the audio line is also used for beat matching. The operating system creates a thread that runs at the highest
priority to perform this real-time audio task. This thread runs continuously and supplies the data to a subroutine to determine if there is sound or
if there is noise on that audio line. The high priority and the constant execution of this
thread prevent the system from entering
Standby or
Hibernate because of the CPU
usage.

WORKAROUND
| 1. | To work around this problem, click the Dancer icon that is located in
the System Notification area. |
| 2. | Click Exit to
close the application. |
| 3. | Alternatively, you can put the system in
Hibernate. To do this, click Start and then click Shut Down. Select Hibernate in the drop-down list box. Click OK. |

STATUS
This behavior is by design. The Dancer.exe application requires a mechanism to know when to start dancing.
You would expect the active listening thread to quit when the Dancer.exe application is
configured to
Stop Dancing to permit the operating system to enter
Standby or to enter
Hibernate as specified in
Power Options. However, as long as Dancer.exe
is active, the computer cannot enter
Standby or
Hibernate. Microsoft is
investigating this issue. More information will be released as it becomes
available.
