WPBT Firmware Power Configuration Persistence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Information handling systems often lack optimized power management configurations, which can lead to inefficient energy usage and require manual reconfiguration upon operating system changes or reinstallation, resulting in suboptimal performance and increased energy consumption.
Innovation Solution
The implementation of a Windows Platform Binary Table (WPBT) within the information handling system firmware allows for the storage and execution of an executable file that provides power management configuration information, persisting across operating system changes and reinstallation, and enabling authentication through digital signatures, ensuring consistent and efficient power management settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual reconfiguration is performed upon operating system changes, then configuration accuracy can be maintained, but time loss and operational complexity increase
Solution Approach 1:
The patent stores optimized power management configuration information in the firmware before operating system installation or changes occur. This preliminary action ensures that when a new operating system is installed, the configuration information is already prepared and can be automatically applied, eliminating the need for manual reconfiguration and reducing time loss while maintaining configuration accuracy.
2Use of energy by moving object
If optimized power management configurations are implemented, then energy efficiency improves, but system complexity increases due to firmware modifications
Solution Approach 1:
The patent implements a Windows Platform Binary Table (WPBT) structure within the existing firmware that serves multiple functions: storing configuration information, providing authentication through digital signatures, and enabling cross-operating system compatibility. This multi-functional approach allows optimized power management without significantly increasing firmware complexity, as the same structure handles multiple tasks.
Solution Approach 2:
The patent introduces an executable file as an intermediary between the firmware and the operating system. This executable file contains the optimized power management configuration information and can be authenticated by the firmware before being executed by the operating system. This intermediary approach allows the firmware to maintain a simple structure while still providing complex power management capabilities through the executable file.
3Stability of the object's composition
If configuration information is stored in firmware, then persistence across operating system changes is achieved, but adaptability to different operating systems decreases
Solution Approach 1:
The patent uses an executable file format that can be authenticated by the firmware but executed by different operating systems. The configuration information within the executable file is stored in a standardized format that can be interpreted by various operating systems, allowing the same firmware-stored configuration to adapt to different operating systems while maintaining persistence across changes.
