ABSTRACT:
A computer includes a primary processor, a primary memory, and a primary input/output (I/O) interface that communicates with the primary processor and the primary memory. A primary display communicates with the primary I/O interface. The primary processor, the primary memory, and the primary display are operated in active and inactive modes and are powered down when the computer is in the inactive mode. A secondary processor dissipates less power than the primary processor. A secondary display communicates with the secondary processor. The secondary processor and the secondary display are powered up when the computer is in the inactive mode. The secondary processor and display support PDA-like functionality when the computer is in the inactive mode.
