Computer system and method for its operation

摘要

The present invention relates to a computer system (1) comprising a power supply unit (2) for generating at least one DC supply voltage (V cc , V aux ) based on an AC supply voltage (V AC ). The computer system (1) further comprises a system board (3) electrically connected to the power supply unit (2). The system board (3) comprises a sequencing microcontroller (13) for selectively activating further components of the system board (3), the further components comprising a chipset (12). The sequencing microcontroller (13) is configured to monitor the state of at least one control signal of the power supply unit (2) and/or the system board (3) to detect a shutdown of the system board (3) and, if a shutdown of the system board (3) is detected, to signal a reboot command to at least the chipset (12) in predetermined intervals until a successful reboot of the system board (3) was detected. The invention further relates to a method of operating a computer system (1).
