BIOS Booting Method Using Switch to Block Power-Failure Signal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modifying BIOS settings in computer systems often requires cutting off main power, leading to potential hardware damage and data loss due to frequent rebooting.
Innovation Solution
A booting method that uses a switch to continuously provide power to the computer system by altering the power-failure signal from the chipset, preventing immediate power cutoff and allowing for safe rebooting without hardware damage.

Engineering Contradiction Analysis
1Reliability
If the main power is cut off and then the computer system is rebooted after BIOS setting modification, then the BIOS setting can be applied, but permanent damage may occur on hardware such as the hard disk and important data may be lost
Solution Approach 1:
A switch is introduced as an intermediary component between the power supply and the computer system. This switch is controlled by a signal generator to selectively block or allow the power-failure signal from the chipset, thereby mediating between the need for power cutoff (to apply BIOS settings) and the need to maintain power (to prevent hardware damage). The switch acts as a controllable gate that enables safe power management during BIOS updates.
2Object-affected harmful factors
If a switch is introduced to control the power-failure signal, then the main power can be maintained continuously, but the device complexity increases
Solution Approach 1:
The switch serves as a minimal intermediary component that adds only the necessary complexity to solve the power management problem. By placing a single switch in the power-failure signal path and controlling it via a signal generator, the system gains precise power control capability without introducing complex power management circuits or multiple additional components.

AI summary
A booting method and a computer system thereof, suitable for rebooting the computer system when a setting value of a basic input output system (BIOS) is modified, are provided. When a modified setting value causes a situation in which a main power is cut off in advance and the computer system is rebooted, a control command is sent to a signal generator for controlling the signal generator to generate a control signal through the BIOS. Then, the control signal is transmitted to a switch by the signal generator for controlling the switch to be turned on or turned off. Afterwards, a power-failure signal transmitted by a chipset is changed by the switch, such that a power supply provides the main power continuously to reboot the computer system.
