Set up S3 sleep state in Vista for significant power savings

Enabling Wake On LAN

This step is optional. Wake On LAN is a setting that allows the computer's NIC(s) to bring the PC out of the S3 sleep state upon receipt of a Magic Packet. If you have no reason to wake the PC up without being physically present, you can skip this step. If you want to be able to remotely access the PC (for file sharing, Remote Desktop, or other uses), you'll want to enable this functionality.

  1. Open Device Manager.
  2. Find the NIC that you want to be able to perform Wake On LAN and open its properties sheet.
  3. Go to the Power Management tab of the Properties sheet.
  4. Check Allow This Device To Wake The Computer, as shown above. If you find that your computer will not stay in the sleep state, you may need to check Only Allow Management Stations To Wake This Computer.
