148 Exploring Your Computer's Features Using the Ambient Light Sensor (ALS) Using the Ambient Light Sensor (ALS) The Ambient Light Sensor (ALS) can sense light levels in the area of your computer and automatically adjust the brightness of the built-in-display, in order to improve screen visibility in low-light and high-light conditions The ALS is enabled by default, but is automatically disabled when you are using the TOSHIBA eco Utility™. To enable or disable the ALS function, click Start, Control Panel, Hardware and Sound, and then Location and Other Sensors. NOTE Do not cover the ALS as the sensor will automatically adjust the computer's built-in-display's brightness to low-light conditions. The ALS controls your computer's built-in-display's brightness. It does not control the brightness of external display devices.
