This invention relates to the field of computer integrated control technology, specifically an integrated triggering method and
system for one-
key recovery of a computer in a power-off state. The method involves monitoring user operations under power-off conditions via hardware circuitry. Under the constraint of the
Recovery module's anti-accidental touch measures, the method arbitrates and determines user-triggered actions, generating a valid trigger
signal and writing it to the wake-up register. Combining an RC
delay circuit and trigger sampling analysis of power-on
voltage changes, the
system automatically enters
Recovery mode upon the next power-on without needing to access the
operating system or
BIOS. After the device is powered off, power data in the power domain is read from the
coin cell battery, and the PG
distortion signal is reconstructed in the
frequency domain. Based on this
signal, stable power-on screening and CLRTC physical trigger detection are performed, automatically clearing the real-time
clock data when conditions are met. The
System Reset module identifies the actual
system crash state by constructing a power-on anomaly
variable domain and automatically triggers a system restart upon detecting a Reset signal, thus achieving one-key maintenance and
recovery of the computer in a
crash state.
