Portable computers of the type commonly referred to as "laptop" computers and "notebook" computers are becoming very popular. They typically include a housing with a lid which is movable between open and closed positions, a display which is mounted on the lid, and a keyboard which is mounted on the housing beneath the lid, the keyboard and display being exposed when the lid is in the open position and being hidden and protected when the lid is in the closed position. These systems also include a battery which serves as a source of power. If a user inadvertently closes the lid without remembering to turn off the power, the system can continue to operate and will run down the battery. A portable computer system includes housing, a lid supported on the housing for movement between open and closed positions, a keyboard supported on the housing below the lid, and a display provided on the lid. When the lid is opened, the keyboard is accessible and the display is visible, whereas when the lid is closed the keyboard and display are hidden and protected. The computer system includes a processor disposed within the housing and having a first operational mode in which it executes instructions and a second operational mode in which it is in a reduced power suspend state from which it can automatically exit in response to a predetermined condition. The system includes an arrangement responsive to closing of the lid when the processor is in its first operational state for switching the processor to its second operational state.
