Abstract
The invention relates to the technical field of data processing, and discloses a real-time clock awakening method based on an embedded controller, which is applied to a BIOS (Basic Input / Output System) of computer equipment and comprises the following steps: acquiring awakening time of the computer equipment input by a user, storing the awakening time and restarting the computer equipment; acquiring current time of the computer equipment through a real-time clock chip of the computer equipment, and calculating a time difference value between the current time and the wake-up time; and if the time difference value is greater than 0, sending the time difference value to an embedded controller of the computer equipment so as to count down the time difference value through a chip clock of the embedded controller and wake up the computer equipment when the countdown is zero. By means of the method, real-time clock wakeup of the computer equipment is achieved in the shutdown state.
