Introduction

Use the Intel Mobile Platform SDK to Retrieve and Track Changes to the 'Power' and 'Display' Context at Runtime.

As the industry moves toward more mobile platforms, the ability of an application to determine power status and scale display capabilities accordingly to save power is becoming more important. With the evolution of mobile platforms, battery life becomes as critical as performance; therefore, applications need to have a way of keeping track of available battery life and be enabled to handle transitions from external (AC) to internal (battery) power sources. Systems would also benefit from being able to scale display richness based on available battery life.

The Intel® Mobile Platform Software Development Kit (Intel® Mobile Platform SDK) provides a common framework for application developers to retrieve properties of "Power" and "Display" status along with a way to track changes to these at runtime. This paper demonstrates how to use the Intel® Mobile Platform SDK to extract Power and Display information. Sample code written in C++, using DirectX* for Microsoft Windows* XP, is also included. The sample application here is based on the Microsoft DirectX (summer 2004) BasicHSLS sample.
