Abstract: A booting method capable of executing a warm boot or a cold boot when a CPU crash occurs in a computer system having a CPU and a memory. First, when the CPU is in a crash state, it is detected that a user wants to execute a hardware reset function or a software reset function. Next, a hardware reset operation is executed to reboot the CPU. Then, when the user chooses to execute the hardware reset function, data and predefined values of the memory are deleted to make the computer system return to a default state. Thereafter, when the user chooses to execute the software reset function, the hardware reset operation is regarded as an operation to replace a software reset operation, and the computer system holds the data and predefined values to make the computer system return to a setting state before the computer system is crashed.

Abstract: The invention provides a method and computer system that can reduce the possibility of cold reset for computer systems. The computer system has a CPU that is used to controls the computer system, a wake-up button that is used to awaken the CPU from a sleep mode, and a battery that supplies power to the computer system. The CPU supports the function of software battery fault handling. The method of the invention includes the procedures (1) When the CPU is in the sleep mode and the computer system's power supply is in an uncertain status, the CPU staying in the sleep mode even a wake-up event occurs. (2) When the CPU is in the sleep mode and the period during which the wake-up button is pressed is less than a predetermined value, the CPU continues to stay in the sleep mode.
