A portable computer system includes a 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.
