description The invention discloses a server case uncovering detection circuit, method, device and equipment and a medium. In the circuit, a mainboard power supply of a BMC is connected with a first end of a case uncovering switch; a second end of the case uncovering switch is connected with a power supply input pin of the RTC; when the BMC is powered on, the mainboard power supply supplies power to the RTC; the BMC is connected with the RTC, and the RTC chip is configured to be a target specific value when the BMC is powered on; when the case is closed, the case cover opening switch controls the RTC to continuously supply power, and a target specific value is kept; when the case is uncovered, the case uncovering switch controls the RTC to be powered down, and the RTC is recovered to the default value of the register; and the BMC obtains the register value of the RTC and detects whether the case is uncovered or not. The circuit can simplify the cover opening detection circuit and reduce the development and product cost.
