Abstract
Energy-saving operating method, in which the disconnecting device records in a nonvolatile memory that temporary disconnection occurred, and thereupon does not execute test and diagnostic routines upon reactivation or does so to a reduced extent.
Claims16
An energy-saving operating method for a first device which can be switched on and off electronically, and carries out test routines after activation, comprising the steps of:
- providing a nonvolatile memory accessable by said first device;
- providing a second device connected to be capable of switching on said first device;
- sending a message from the second device to the first device that an imminent disconnection of the first device is a temporary disconnection;
- storing information that the imminent disconnection of the first device is a temporary disconnection in the nonvolatile memory;
- disconnecting a voltage supply of the first device;
- the second device effecting reactivation of the first device on a basis of a predetermined event;
- shortening an initialization phase for reactivating the first device based on the information stored in the nonvolatile memory that a temporary disconnection occurred.
An energy-saving operating method for a device which can be switched on and off electronically, and which carries out test routines after activation, comprising the steps of:
- providing a nonvolatile memory accessible by the device;
- providing a clock which is independent of a power supply for the device;
- if the device is in an operating intermission, storing information regarding the operating intermission at regular intervals together with a time detail from the clock in the nonvolatile memory,
- if the device leaves an operating intermission, erasing the stored time information;
- after activation, checking to see whether the nonvolatile memory contains a valid time detail which is not out of date compared with a predetermined limit, and, if within the predetermined limit shortening an initialization of the device.
