Abstract
Abstract A computer typically includes a power switch. A method of power switch management of the computer may be implemented in which a system power operation of the computer is performed if the power switch has been activated in a first manner and an operation of the computer other than a system power operation of the computer is performed if the power switch has been activated in a second manner. The operation of the computer other than a system power operation of the computer can include, for example, a suspend/resume operation of the computer.
