Abstract
A portable computer supported by a power management system that responds to a closed state and an open state of a flat panel display. A closed position and an open position of a lid (housing the display) of the portable computer is detected by a switch mounted adjacent to a display latch device. When the display is moved to the closed position, a switch-on signal is supplied to the power management system which allows the computer system components to enter a suspend mode, consuming less power than while in a full-power on mode. This will turn off the power after saving the current memory and system information to disk. The display latch device includes a knob having a latch hook and a groove formed in a top portion of a main body selectively locking and releasing the latch hook. This invention provides a simple location of the switch and the arrangement may eliminate special function keys manually operated for turning off the computer or invoking a power management signal. Further, the present invention provides for a maximization of battery life. The portable computer can correspond to a notebook computer, laptop computer, or other compact or lightweight computer. The present invention can be used in conjunction with a portable word processor also.
