Hello, my Mac isn't sleeping when idle.


I went in Terminal and typed in: pmset -g assertions (got that from http://www.adeepbite.com/lion-seems-having-insomnia-it-doesnt-sleep-easily/ )


This is my result:

1/1/13 6:26:57 PM CST   

   Assertion status system-wide:

   PreventUserIdleDisplaySleep   0

   PreventSystemSleep               0

   PreventUserIdleSystemSleep   1

   ExternalMedia                         0

   UserIsActive                           0

   ApplePushServiceTask            0

   BackgroundTask                     1

  pid 569(helpd): [0x0000000c000003cd] 00:20:55 BackgroundTask named: "com.apple.helpd.sdmbuilding"



It seems that my Headset: Microsoft LifeChat LX-3000, is causing my computer to stay awake.


How can I get it to sleep without unplugging it from my computer?
