Abstract
A computer system that includes a power supply unit that generates at least one secondary supply voltage (Vcc) and an auxiliary voltage (Vaux) based on an AC supply voltage (VAC), and a system board electrically connected to the power supply unit, the system board comprising a sequencing microcontroller that selectively activates further components of the system board, the further components comprising a chipset, wherein the sequencing microcontroller is configured to monitor the state of at least one control signal of the power supply unit and/or the system board to detect a failure of the AC supply voltage (VAC) and signal the failure of the AC supply voltage (VAC) to at least the chipset.
