Abstract
A computer system having a central machine, work stations and a background memory, wherein the central machine has an active state, a standby state, a battery power supply state and a rest state, a heart memory maintains the actual time and contains information indicating at what time of what days the active state should prevail. When the mains power supply fails the central machine goes over to the battery power supply state. When the latter is failing, the battery indicator is set in an 'error' state. When the mains power supply reappears, it is inspected whether then the active state has to be maintained and under the control of an 'error' position an initial program load operation is carried out. If admissible the central machine goes over to the standby state.
