Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Computer devices, such as notebooks, often fail to boot in low temperature environments due to insufficient battery power and voltage, making it challenging to activate system components even when a heater is used to heat the hard disk.
Innovation Solution
A method and device that utilize temperature sensors and a heater to monitor and adjust the hard disk and battery temperatures, activating the system components only when both reach predetermined levels, ensuring sufficient power and voltage for booting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a heater is activated to heat the hard disk, then the hard disk reaches booting temperature, but the battery power is insufficient and voltage cannot reach booting voltage
Solution Approach 1:
The system performs preliminary warming of the battery cell before attempting to boot the system. The embedded controller activates the battery heater in advance to raise the battery temperature to a predetermined level, ensuring sufficient power and voltage are available when the power button is pressed, thus resolving the contradiction between heating the hard disk and having sufficient battery power.
2Temperature
If a heater is activated to heat the hard disk, then the hard disk reaches booting temperature, but the voltage of the battery cannot reach booting voltage
Solution Approach 1:
The system performs preliminary warming of the battery cell before attempting to boot the system. The embedded controller activates the battery heater in advance to raise the battery temperature to a predetermined level, ensuring sufficient power and voltage are available when the power button is pressed, thus resolving the contradiction between heating the hard disk and having sufficient battery power.
3Productivity
If the system checks battery voltage after heating the hard disk, then booting can proceed, but the battery may still be too cold to provide sufficient power
Solution Approach 1:
The system performs preliminary warming of the battery cell before attempting to boot the system. The embedded controller activates the battery heater in advance to raise the battery temperature to a predetermined level, ensuring sufficient power and voltage are available when the power button is pressed, thus resolving the contradiction between heating the hard disk and having sufficient battery power.

AI summary
A method for booting a computer device under a low temperature state is provided. A trigger signal is detected when a power button is pressed. A hard disk temperature of a hard disk is obtained via a temperature sensor to determine whether the hard disk temperature is less than a first predetermined temperature. If so, a heater is activated to heat the hard disk until the hard disk temperature is greater than the first predetermined temperature. If the hard disk temperature is greater than the first predetermined temperature, the heater is turned off and afterwards a voltage of a battery cell is checked if the voltage has reached a predetermined voltage. If the voltage of the battery cell has reached the predetermined voltage, a system component of a computer device is activated.
