# Surface Brightness Control

When deploying Surface devices in point of sale or other “always-on”
kiosk scenarios, you can optimize power management using the new Surface
Brightness Control app.

Available for download with [Surface Tools for
IT](https://www.microsoft.com/download/details.aspx?id=46703), Surface Brightness Control is
designed to help reduce thermal load and lower the overall carbon
footprint for deployed Surface devices. The tool automatically dims the screen when not in use and
includes the following configuration options:

- Period of inactivity before dimming the display.

- Brightness level when dimmed.

- Maximum brightness level when in use.

**To run Surface Brightness Control:**

- Install surfacebrightnesscontrol.msi on the target device and Surface Brightness Control
  will begin working immediately.

You can adjust the default values via the Windows Registry. For more
