Abstract

The invention discloses a computer system and a power supply control device thereof. The device comprises a temperature sensor, a first voltage converter, an over-temperature protection unit, a reset unit and a second voltage converter. The temperature sensor is used for sensing measuring temperature and outputting a sensing signal. The first voltage converter is used for converting the power supply voltage of the computer system into first voltage. The over-temperature protection unit is used for receiving the first voltage and determining whether to output the first voltage according to the sensing signal. The reset unit is used for determining whether to generate a reset signal according to the level of the power supply voltage when receiving the first voltage from the over-temperature protection unit. The second voltage converter is used for generating an activation signal according to the reset signal so as to enable an embedded controller.

Description

technical field [0001] The present invention relates to a computer system and its power control device, and in particular to a computer system with an over-temperature protection mechanism and its power control device. Background technique [0002] figure 1 A partial schematic diagram of a traditional computer system. refer to figure 1 , the conventional computer system 100 includes a temperature sensor 110, an embedded controller 120, resistors R11 and R12, a capacitor C1 and a diode Z1. Under normal conditions of the conventional computer system 100 , the temperature sensor 110 will not generate the sensing signal STH1 with a low logic level. At this time, the voltage V1 will pass through the conduction path of the resistor R12 and the capacitor C1, so that the embedded controller 120 works normally. [0003] Conversely, when the conventional computer system 100 is overheated due to the CPU or a certain working element, the temperature sensor 110 will generate a sensin...
