ABSTRACT:
A method and apparatus for suspending the operation of a computer at any desired point and resuming operation at exactly the same point is disclosed. At the point where suspension is chosen, the current state of the computer is stored in the computer's Random Access Memory and power is disconnected to all other components in the computer. When resumption of operation is commanded, power is restored to all components and the current computer state is retrieved from the Random Access Memory and restored, allowing operations to continue from exactly the same point as they were suspended. The invention encourages turning off the computer for even brief periods of non-use, as there is almost no waiting time when resumption of operation is commanded.
