Abstract

The embodiment of the invention provides a CMOS data clearing circuit and computer equipment, and relates to the technical field of computer equipment. The MOS data clearing circuit comprises a reset signal output circuit, a first time delay module, a second time delay module, an embedded controller and a CMOS data clearing module, and the reset signal output circuit is used to output a reset signal to the first time delay module. After the first time delay module receives the reset signal and delays for a first preset time length, the first time delay module sends a restart signal to the embedded controller and the second time delay module. After the second time delay module receives the restart signal and delays for a second preset time length, the second delay module sends a clearing signal to the CMOS data clearing module so as to clear data in a CMOS chip. When a reset key is used for restarting the embedded controller, the restarting signal of the embedded controller is used for triggering and clearing data in the CMOS chip, so the clearing function is achieved only through the existing key, the disassembling action is avoided, and the maintenance or after-sales operation process is simplified.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of computer equipment, in particular to a CMOS data clearing circuit and computer equipment. Background technique [0002] At present, computers are designed with a real-time clock (RTC) battery, which can be a button battery or integrated into the system battery, to maintain the time of the system and basic input and output when the system is turned off and powered off. Related settings in the system (Basic Input Output System, BIOS) remain unchanged. When the machine needs to clear the Complementary Metal Oxide Semiconductor (CMOS), currently the purpose of clearing the CMOS is to disassemble the machine and remove the battery. This operation is difficult to complete on the user side and increases the risk of burning the machine. Contents of the invention [0003] Since it is difficult to clear the CMOS data by disassembling the machine and removing the battery, it is difficult to ...
