AUTOMATIC BACKLIGHT INTENSITY ADJUSTMENT IN AN EMBEDDED OPERATING SYSTEM ENVIRONMENT
First Claim
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 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 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.

Abstract
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.

8. 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; maintaining, through a backlight driver component of the embedded operating system, a backlight of at least one I/O device of the data processing system at an intensity level lower than an intensity level associated with a normal operation thereof when the battery is detected to be in a critical state by the battery driver component, 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; and modifying, through the backlight driver component, the intensity level of the backlight back to the intensity level associated with the normal operation when the battery is detected to be out of the critical state by the battery driver component. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A data processing system executing an embedded operating system thereon comprising:
-
a battery; a battery driver component integrated with the embedded operating system executing on the data processing system, the battery driver component being configured to monitor a state of the battery when the data processing system derives power from the battery; at least one I/O device; a backlight associated with the at least one I/O device; and a backlight driver component integrated with the embedded operating system, the backlight driver component being configured to modify an intensity level of the backlight from a current level associated with a normal operation of the data processing system to an intensity level lower than the current level when the battery is detected to be in a critical state to prolong a lifetime of the battery, and 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. - View Dependent Claims (16, 17, 18, 19, 20)
