Using the Ambient Light Sensor in Bright or Low-
Light Environments:
NOTE:
Your laptop computer may not have an ambient light sensor.
NOTE:
The ambient light sensor adjusts the display brightness on your laptop
computer only. It does not control the brightness on external monitors or projectors.
The ambient light sensor is located on the front of the computer display. The
sensor detects available environmental light and automatically increases or
decreases the display backlighting to compensate for low-light and high-light
environments.
