Abstract:
1. A method comprising: monitoring, through a battery driver component of an embedded operating system executing on a data processing system deriving power from a battery, a state of the battery; and modifying, through a backlight driver component of the embedded operating system, an intensity level of a backlight of at least one Input/Output (I/O) device of the data processing system from an intensity level associated with a normal operation thereof to a lower intensity level when the battery is detected to be in a critical state by the battery driver component to prolong a lifetime thereof, the critical state being associated with a remaining charge on the battery being below a threshold required to maintain the data processing system in a powered on state, the modification of the intensity level of the backlight comprising switching between a plurality of intensity levels of the backlight defined through an Original Design Manufacturer (ODM) thereof and stored in at least one registry setting associated with the embedded operating system, and the plurality of intensity levels comprising both the intensity level associated with the normal operation and the lower intensity level.
