Abstract

A pen-based personal computer includes a main power switch for initial power-up. The pen-based portable personal computer includes a keyboard controller which controls power management of the battery and places the pen-based portable personal computer in a hibernate state after a predetermined period of inactivity. The system can be awakened from the hibernate state by contact of a passive stylus with the digitizer panel. In order to place the power management of the battery under the control of the keyboard controller, a wake-up signal is generated at power-up just long enough to enable the keyboard controller to take control of the power management of the battery.
