ABSTRACT:
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.
