Abstract
A portable computer system includes an input device such as a keyboard, a display, and a processor which is operable in a normal operational mode and in a reduced power mode, the processor carrying out program execution in each of the normal operational mode and reduced power mode. A timing arrangement switches the processor from its normal operational mode to its reduced power mode in response to the absence of any of a plurality of predetermined events during a predetermined time interval, the predetermined events including actuation of keys on the keyboard and transmission of information to the video display.
