Solution Overview
Problem
Existing Information Handling Systems (IHSs) face challenges in managing thermal loads during pre-boot operations, particularly during computationally intensive tasks like large file transfers or downloads, which can lead to overheating and degrade user experience.
Innovation Solution
Implementing thermal-aware network selection methods that adjust network communication speed, bandwidth, or technology based on temperature data and policy rules, including fan speed control and power state modifications, to manage thermal loads and prevent overheating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If high-speed network communication is used during pre-boot operations, then download speed and productivity are improved, but thermal loading increases causing overheating
Solution Approach 1:
The system dynamically adjusts network communication parameters (speed, bandwidth, technology) based on real-time thermal conditions. The pre-boot application monitors temperature data from thermal zones and modifies network operations accordingly, transitioning between high-speed and low-speed modes to balance productivity and thermal management
Solution Approach 2:
The patent changes physical parameters of network communication (speed, bandwidth, power consumption) in response to thermal conditions. When temperature exceeds thresholds, the system modifies network parameters to reduce power consumption and thermal generation, thereby resolving the contradiction between high-speed operation and thermal management
2Adaptability or versatility
If computationally intensive tasks are performed during pre-boot, then system functionality is improved, but thermal loading increases degrading user experience
Solution Approach 1:
The system implements a feedback mechanism where the pre-boot application continuously monitors thermal data from the EC and adjusts network operations based on temperature conditions. This closed-loop control ensures that computationally intensive tasks are performed within thermal constraints, preventing overheating while maintaining necessary functionality
Solution Approach 2:
The system takes preliminary action by monitoring thermal conditions before initiating or maintaining high-speed network operations. When thermal thresholds are approached, the system proactively reduces network activity to prevent overheating, rather than reacting after the problem occurs

AI summary
Systems and methods for thermal-aware network selection in an Information Handling System (IHS) are described. In an illustrative, non-limiting embodiment, an IHS may include a processor and a memory coupled to the processor, the memory having program instructions stored thereon that, upon execution, cause the IHS to: receive telemetry data from an Embedded Controller (EC) coupled to the processor; and in response to a determination that a policy is met based, at least in part, upon the telemetry data, modify a network communication of a pre-boot application.
