PowerDown consists of two batch files and two freeware utilities.

According to the press release, the setup batch file:

  • Creates a Windows scheduled task to run the power-saving batch file after X minutes of idle time.
  • Copies the power-saving batch file somewhere local.
  • Copies the two freeware utilities into the system.

The power-saving batch file:

  • Is run when the scheduled task notices that there have been X minutes of idle time.
  • Checks whether the computer has opted out of power-saving.
  • Checks whether anybody is logged in.
  • If not, it shuts down.
