1. An energy-conserving computer remotely reachable for establishing instant communications, comprising:

  • (a) a switchable power-supply system comprising switching means, for selectively providing switchable power;

    (b) a group of switchable circuit means in power connection with said switchable power-supply system, said group of switchable circuit means comprising main microprocessor circuitry and nonvolatile memory storage;

    (c) a keep-alive power-supply system for continuously providing keep-alive DC power;

    (d) a group of keep-alive circuit means in power connection with said keep-alive power-supply system, said group of circuit means comprising a keep-alive communication circuit, keep-alive memory circuitry, and keep-alive control means; and

    (e) keep-alive operating instructions stored in said keep-alive memory circuitry;

    whereby said keep-alive operating instructions are provided for allowing said keep-alive control means to request said keep-alive communication circuit to detect a communication signal in a keep-alive state in which said switchable power-supply system is deactivated for conserving energy.
