A computer system that includes a power supply unit that generates at least one secondary supply voltage (V) and an auxiliary voltage (V) based on an AC supply voltage (V), 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 (V) and signal the failure of the AC supply voltage (V) to at least the chipset.

Computer systems and methods of detecting AC failure

An energy-saving circuit applies to a peripheral device for connection to a data bus of a host system. The energy-saving circuit includes a monitoring circuit for monitoring a communication via the data bus, a holding circuit for holding a connection state of the peripheral device, at least one switching element for interrupting a supply voltage for the peripheral device, and a control circuit. The control circuit is set up to recognize by means of the monitoring circuit the beginning of an idle state of the data bus, to hold the connection state of the peripheral device by activation of the holding circuit upon recognition of the idle state, and to interrupt the feeding of a supply voltage for the peripheral device by opening the at least one switching element.

Energy-saving circuit for a peripheral device, peripheral device, switching device and method of operation

A computer system has at least one supply device, at least one system component with a data-processing device and at least one communications device. The supply device has at least one programmable control module that is supplied with an operating energy by a voltage source coupled to the at least one supply device and operated independently thereof.

Computer system and method for energy-saving operation of a computer system

A computer system comprising a CPU, a data bus, components and a communication module for the administration of the CPU or components. The communication module comprises a data interface coupled to the data bus of the computer system. The user interface comprises a display unit and a control panel. A control unit is coupled to the user interface and the data interface for transmitting data to and from the CPU or components using the data bus. A memory is provided for the storage of configuration parameters and status information, which is coupled to the control unit via a memory bus. The communication module is adapted for obtaining system information of the components without using the CPU of the computer system and performing a configuration of the components using the configuration parameters.
