Two methods and apparatus for reducing power consumption in battery powered computers are disclosed. The first places the computer in a sleep mode whenever a certain data input function is called. The second applies statistical analysis to calls to another data input function. By measuring the number of times the computer has tried to read data from the keyboard over the past predefined period, the variance between the high and low number of calls over the present and preceding time periods, and whether the number of times the computer has tried to read data has both exceeded the present limit and remained within the preset variance limit for a predefined minimum time, the desirability of activating a sleep mode for the computer can be determined.

Method for reducing power consumption includes comparing variance in

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.
