Vorrichtung zur Verminderung des Energieverbrauchs eines Rechnersystems.

摘要

A battery powered computer system (C) monitors the address bus (20) to determine when selected peripheral devices have not been accessed for a preset amount of time. When the preset amount of time has passed the system powers itself down and stops the system clock, placing it in a standby mode. The system is awakened by depressing a standby switch, unless there is insufficient energy in the batteries, under which circumstances an AC power source must be connected before the system can be re-awakened.
