Information Device Standby Mode Power Limit Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Information processing devices, such as laptops, can enter unintended states during standby mode, leading to increased chassis surface temperature due to background processing, which may result in heat dissipation issues and user dissatisfaction.
Innovation Solution
Implementing a mode control system that switches between low power consumption states, including a first operating state for background processing and a second low power consumption state like hibernation, based on temperature thresholds and user actions, to manage power consumption and prevent overheating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the device enters a standby mode with background processing enabled, then power consumption is reduced and the display is stopped, but the chassis surface temperature increases due to continuous processing
Solution Approach 1:
The patent implements dynamic adjustment of power consumption limits based on temperature conditions. The power consumption limit adjustment unit continuously monitors chassis temperature and dynamically adjusts the power consumption limit in the first operating state accordingly. When temperature exceeds a threshold, the system transitions to a second operating state with lower power consumption, thereby resolving the contradiction between maintaining background processing and controlling temperature.
Solution Approach 2:
The system changes operational parameters (power consumption limits and operating states) based on temperature conditions. By adjusting the power consumption limit parameter dynamically and transitioning between different operating states (first and second operating states), the system maintains background processing capability while preventing excessive temperature rise in standby mode.
2Productivity
If the device allows background processing in standby mode, then useful processing continues, but the device may enter unintended states that users did not expect
Solution Approach 1:
The patent implements a feedback mechanism where the power consumption limit adjustment unit monitors temperature and system state, and adjusts power consumption limits accordingly. This feedback loop ensures that the system responds to actual operating conditions, preventing unintended states by transitioning to a second operating state when temperature thresholds are exceeded, thereby aligning system behavior with user expectations during standby mode.
3Temperature
If the device transitions to a second low power consumption state when temperature exceeds threshold, then temperature is controlled, but background processing is interrupted
Solution Approach 1:
The system implements periodic monitoring of temperature and dynamic adjustment between operating states. By transitioning between the first operating state (with background processing) and the second operating state (with lower power consumption) based on temperature thresholds, the system achieves periodic operation that balances temperature control with background processing continuity, allowing processing to resume when temperature conditions improve.

AI summary
An information processing device suppresses the entering of a state unintended by a user in a standby mode. The information processing device, which has a standby mode and a normal operation mode, has a mode control portion changing the mode to the standby mode of bringing the state into a first low power consumption state and configured to be switched to a first operating state in which background processing is executed in response to a stop of a display of a display portion, and a power setting processing portion configured to set a first upper limit power consumption in the first operating state and a second upper limit power consumption in a second operating state in the normal operation mode, and set the first upper limit power consumption so as to be lower than the second upper limit power consumption when the mode control portion changes the mode to the standby mode.
