PROBLEM TO BE SOLVED: To provide a game machine which makes it easy to cancel a power- saving mode and never returns accidentally to a game processing mode, and to provide a power-saving management program which is executed thereupon. SOLUTION: When an input from an operation switch meets a return condition (step S31) the portable game machine in sleep mode cancels the sleep mode (step S32) and generates a return window (step S33). Then a 10-second timer is set (step S34) and the return window is displayed on an LCD (step S36). When an indication from a user shows a return from the sleep mode is possible, the return window is erased (step S49) and game data and a game picture before the sleep mode is entered are put back (step S40), so that normal game processing is restarted. When there is no input with the operation switch for 10 or more seconds or when the user selects an unreturnable state, the sleep mode is entered again. |
