Embedded Subsystem Power Control for Notebook Standby
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current computer systems consume excessive power due to embedded subsystems remaining in an operating state even when the main computer subsystem is in a standby or shutdown state, leading to short stand-by times.
Innovation Solution
Implement a method to control the embedded subsystem's power state based on the main computer subsystem's state, turning off or reducing power when the main subsystem is on and enabling operation only during low-power or shutdown states to conserve energy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the embedded subsystem stays in an operating state to ensure real-time email sending and receiving, then the preset function reliability is improved, but the power consumption increases and stand-by time decreases
Solution Approach 1:
The embedded subsystem dynamically adjusts its operational state based on the main computer subsystem's state. When the main subsystem is in a low-power or shut-down state, the embedded subsystem activates to handle email functions. When the main subsystem is powered on, the embedded subsystem transitions to a low-power or shut-off state, as the main subsystem can then handle email functions. This dynamic state adjustment resolves the contradiction by making the system adaptive rather than static.
Solution Approach 2:
The embedded subsystem operates periodically rather than continuously, activating only when the main computer subsystem is in a low-power or shut-down state and deactivating when the main subsystem is powered on. This periodic operation pattern ensures email functions are maintained while significantly reducing overall power consumption compared to continuous operation.

3Use of energy by moving object
If the embedded subsystem is turned off when the main computer subsystem is powered on, then the power consumption is reduced, but the real-time email sending and receiving function may be affected
Solution Approach 1:
The email sending and receiving function is implemented through multiple pathways: the embedded subsystem can handle email functions independently, and the main computer subsystem also has the capability to handle email functions when powered on. This multi-functionality allows the system to switch between different operational modes depending on the main subsystem's state, ensuring email functionality is maintained regardless of which subsystem is active.
Solution Approach 2:
The embedded subsystem acts as an intermediary that bridges the gap between power conservation and functional availability. When the main subsystem is off, the embedded subsystem activates to maintain email functionality. When the main subsystem is on, the embedded subsystem deactivates as the main subsystem takes over email functions. This intermediary approach ensures seamless transition and maintains functionality while optimizing power consumption.
