Features of some Intel processors, including the Pentium, for reducing power consumption. These features operate at two levels: the microprocessor and the system. The processor can enter a low power state during non-processor intensive tasks (such as word processing), or a very low-power state when the computer is not in use ("sleep" mode). At the system level, system management mode can slow down, suspend, or completely shut down various system components to save energy. (1995-05-06)
