Power management

You can consider the power management setting as power-saving mode. Power-saving has six levels. Disabling power-saving mode provides the greatest Wi-Fi network performance.

Power management lets you select a balance between power consumption and Wi-Fi adapter performance. The Wi-Fi adapter power settings balance the computer power source and battery.

  • Default value: Default power settings are based on the power source of the computer.
  • Manual: Adjust the power setting as desired. Use the lowest setting for maximum battery life. Use the highest setting for maximum performance.
Windows® 10, Windows 7*, and Windows 8.1*
