ABSTRACT:
A system especially suited for powering up and down electronic equipment operated to a power conservation mode, which conserves more power than other power conservation efforts. The system is operated by hitting any key of a keyboard which provides data entry signals via a plurality of data lines. An embodiment disclosed provides a flip-flop having power on and power off outputs and also inputs which change the flip-flop between set and reset states. A first isolation switch connects at least one of the plurality of keyboard data lines to the flip-flop for conditioning the flip-flop into the one of its set and reset states which provides power on output when serial data is provided, as when any key of the keyboard is pressed. A second isolation switch had data entry signals transmitted through it, and is switched by one of the outputs of the flip-flop so that data entry signals are prevented from being transmitted therethrough except when the flip-flop is in the one of its set and reset states which provides power on output when any key of the keyboard is pressed. The system may be continuously operated by direct connection to a power source, and may have equipment to be powered up and down connected to said power source via a power supply which supply is switched on and off by the power on and power off outputs, respectively, of the flip flop. The flip-flop may be conditioned into the one of its set and reset states which provides power off output via a sleep signal provided as an input via a sleep signal line.
