Portable computer and operating method thereof

摘要

A portable computer and an operating method thereof are provided. The portable computer comprises an input device, a power button, a non-volatile memory, a central processing unit (CPU), an embedded controller (EC), and a chipset. The input device inputs a user password, and the non-volatile memory stores a default password. The EC, in a soft off status, determines whether the power button protection item is enabled. The EC locks the power button if the power button protection item is enabled. The EC determines whether the user password is the same as the default password. The EC unlocks the power button if the user password is the same as the default password. The chipset is coupled to the non-volatile memory, the CPU and the EC.

1. A portable computer, comprising:
an input device for inputting a user password; a power button; a non-volatile memory for storing a default password; a central processing unit (CPU); an embedded controller (EC) for, in a soft off status, determining whether a power button protection item is enabled, wherein the EC locks the power button if the power button protection item is enabled, and the EC determines whether the user password is the same as the default password and unlocks the power button if the user password is the same as the default password; and a chipset coupled to the non-volatile memory, the CPU and the EC; wherein the CPU:
determines whether to enter a basic I/O system (BIOS) menu,determines whether the status of the power button protection item changes if the CPU enters the BIOS menu,determines whether the power button protection item is enabled if the status of the power button protection item changes, andreceives the default password and stores the status of the power button protection item and the default password to the non-volatile memory if the power button protection item is enabled.
