Abstract
Official abstract text for this publication.
A method includes monitoring, through a battery driver component of a embedded operating system executing on a data processing system deriving power from a battery, a state of the battery. The method also includes modifying, through a backlight driver component of the embedded operating system, an intensity level of a backlight of one or more Input/Output (I/O) devices of the data processing system from a current level associated with a normal operation thereof to an intensity level lower than the current level when the battery is detected to be in a critical state to prolong a lifetime thereof. The critical state is associated with a remaining charge on the battery being below a threshold required to maintain the data processing system in a powered on state.
First claim
Opening claim text (preview).
What is claimed is: 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 low…
