Abstract

Provided are a power supply management device and a power supply management method. The power supply management device suitable for a computer system comprises a reset counting unit, an interval recording unit and a comparing unit, wherein the reset counting unit can receive reset requests and can count reset times of the computer system according to the reset requests, the interval recording unit can receive reset requests to record interval time between the reset request and the former reset request, and the comparing unit is coupled with the reset counting unit and the interval recording unit to compare the reset times and the interval time with original set to judge whether the computer system is reset or closed and judge whether reset time is set for the computer system. Thus, the power supply management system can avoid repeated and discontinuous reset on the computer system to protect the computer system.

Description

technical field [0001] The invention relates to a power management technology of a computer system, and in particular to a power management device and a power management method thereof. Background technique [0002] Most of today's computer systems are equipped with a power management device on the motherboard, and the power management device will monitor the corresponding signals of each device in the computer system at any time, so as to start or reset the computer system. [0003] For example, if the computer system is to be turned on, the power-on signal, reset signal, etc. and other power-related signals are sent to the power management device, and the corresponding computer system startup and reset procedures are performed by the power management device. Or, when some devices in the computer system are abnormal, such as: the central processing unit (CPU) is overheated, a peripheral device sends a setting error signal and the computer system needs to be restarted / reset...
