Fig. 5 is a flowchart showing the control steps of the microcomputer 60 according to the present invention. Referring to FIG. 5, step S 100 determines whether a start signal is input from the start switch 40. When an enable signal is input, the interrupt handler 62 in the microcomputer 60 executes an interrupt processing routine and the process proceeds to step S105, where step S105 determines whether the portable computer 10 is in a power-off state. When the computer 10 is in a power-off state, it is judged in step S110 whether the activation serial number is continuously input for more than a predetermined time or a fixed time. If so, the flow proceeds to step S115 to turn on the power of the portable computer 10; that is, the power supply 80 provides main power to the system. If the judgment in step S105 is negative, the flow proceeds to step S120. Step S120 determines whether the portable computer 10 is in a sleep mode. If yes, step S125 determines whether the start signal is continuously input for more than a fixed period of time. If the result of the determination in step S125 is YES, the portable computer 10 is woken up in step S130. If the portable computer 10 is in a normal state, the flow proceeds to step S135 to display a menu list 100 on the screen of the display panel 50. That is, the startup program 72 is executed to display the applications registered in the menu list 100. In the middle of the displayed menu list 100, there is a line from 10 (please read the precautions on the back before filling this page)-· 11 ----- Order --------- Line · This paper size applies to China National Standard (CNS) A4 specification (210 X 297 mm) 1232370 A7 6508pif.doc / 008 5. Description of the invention (g) Blank option 110 refers to the blank. When the portable computer 10 is in the power-off state or the sleep mode, the microcomputer 60 only wakes up the portable computer 10 to display the menu list 100 when the startup signal is input by the startup switch 40. When the computer 10 is in the normal state, the microcomputer 60 will immediately respond to the input of the start signal and display the menu list 100 on the screen. This operation only reacts when an activation signal is generated by electrically connecting the movable contact 41 to the fixed contact 44. In step S140, the microcomputer 60 determines whether the start signal is still input when the menu list 100 is displayed. If there is no input, the flow proceeds to step S145 to determine whether the predetermined waiting time has expired. If the waiting time has elapsed, the portable computer 10 enters the sleep mode in step S150. Therefore, the present invention can prevent the portable computer 10 from continuously consuming unnecessary power. When an activation signal is input in step S140, the microcomputer 60 determines whether a menu useful for executing an application is selected in step SB5. If so, the flow proceeds to step S160 to execute the selected application, and in the following step S165, the menu list 1 is deleted. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs (please read the precautions on the back before filling this page). If there is no selected application in step S 155, it will be determined in step s 170 whether there is an input activation signal. To scroll through the menus. That is, it is determined whether the movable contact 41 of the start switch 40 is pushed in one direction (forward or backward). If there is an input to scroll the menu, the flow proceeds to step S175 to scroll the cursor of the menu list 100 in a corresponding direction. If there is no input to scroll the menu, step S170 returns to step S140. According to the present invention, the paper size of the portable computer is applicable to the Chinese National Standard (CNS) A4 (210 x 297 mm) even if the user presses it by mistake.
