Abstract
An improved system and method for controlling the brightness of indicator lights used on portable information handling systems. Various embodiments of the invention optimize the output of the indicator lights in accordance with detected ambient light levels. The brightness of the indicator lights can be adjusted automatically in accordance with a fixed response curve or manually by user inputs. In some embodiments, the brightness is adjusted in accordance with user-designated preferences that are stored in a brightness preference table and correlated with detected ambient light levels.
