    Info: This breaks a connection between an application and system BIOS
          made by a previous call to INT 15H 5301H, INT 15H 5302H, or
          INT 15H 5303H.

          This says, "I no longer wish to help manage power."

   Notes: This restore the BIOS defaults for power management.  However,
          timers and device enable/disable settings (such as made via
          INT 15H 5307H) will remain in effect.
