+## Summary of recommendations for IT administrators
+
+To ensure Surface devices across your organization fully benefit from Surface power optimization features:
+
+- Exclude Surface devices from any existing power management policy settings and let the Surface default policy control the power policy and behavior of the device.
+- If you must manage the power profile of devices across your network (such as in highly managed organizations), use the powercfg command tool to export the power profile from the factory image of the Surface device and then import it into the provisioning package for your Surface devices. For more information, refer to [Configure power settings](https://docs.microsoft.com/windows-hardware/customize/power-settings/configure-power-settings).
+- Always use the newest available version of the drivers and firmware for your devices and for the version of Windows 10 they're running. For more information, refer to [Deploying the latest firmware and drivers for Surface devices](deploy-the-latest-firmware-and-drivers-for-surface-devices.md)
+- Avoid creating custom power profiles or adjusting advanced power settings not visible in the default UI  (**System** > **Power & sleep**). For more information, refer to User best practices for extended battery life in this document.

+## Utilizing the custom power profile in Surface

+If you go into the power options on a  surface device, you'll see that there's a single power plan available. This is the custom power profile. And if you go to the advanced power settings, you’ll see a much smaller subset of power options compared to a generic PC running Windows 10. Unlike generic devices, Surface has firmware and custom components to manage these power options.

 Surface provides a simplified UI in accord with best practice power
 setting recommendations. In general, it's recommended to only adjust settings visible in the default user interface and avoid configuring advanced power settings or Group Policy settings. Using the default screen and sleep timeouts while avoiding maximum
 brightness levels are the most effective ways for users to maintain
