Abstract

A mainboard battery detection device is suitable for detecting a battery and comprises a transistor, a first resistor, a second resistor, a substrate management controller and a voltage follower; thesubstrate management controller controls the transistor to be conducted or not conducted; the voltage follower receives a first input voltage from the second resistor, receives a same second input voltage, and outputs the same voltage as the second input voltage to the substrate management controller. The substrate management controller receives a first output voltage and a second output voltage from the voltage follower respectively when the transistor is not conducted and conducted; the substrate management controller compares whether the difference between the first output voltage and the second output voltage is larger than a default voltage value or not to judge whether the battery does not exist or not.

Description

【Technical field】 [0001] The invention relates to a power detection device, in particular to a detection device for a motherboard battery. 【Background technique】 [0002] Existing servers have a CMOS (Complementary Metal-Oxide-Semiconductor) RAM (Random Access Memory) chip for reading and writing data on one of the motherboards and storing the current hardware-related configuration of the system, (hereinafter referred to as the CMOS RAM chip for short) ), the CMOS RAM chip maintains the current time by a real-time frequency (RTC; Real Time Clock), when the server power is turned off, the CMOS RAM chip uses such as figure 1 A battery 21 of the motherboard is shown receiving power to maintain the readable state of the real-time frequency and retain its stored data. When the battery 21 fails to supply power normally, the data originally stored in the CMOS RAM chip will be lost. Therefore, the server usually monitors the power of the battery to avoid loss of important CMOS RAM ...
