Abstract: 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.

Abstract: A method for controlling a sensor includes steps of: sensing an object for determining whether the object is within a sensing range of the sensor; if it is determined that the object is not within the sensing range, the sensor is turned into a non-active mode for a predicted non-active time, wherein the predicted non-active time is calculated based on a predetermined or a historical non-active time; sensing the object for determining whether the object is within the sensing range during the predicted non-active time; and if it is determined that the object is not within the sensing range during the predicted non-active time, the sensor is turned into a sleep mode for an predicted sleep time, wherein the predicted sleep time is calculated based on the predetermined non-active time and a predetermined sleep time, or is calculated based on the historical non-active time and a historical sleep time.

Abstract: A computer system is disclosed. The computer system comprises a near field communication (NFC) tag and a computer. The computer comprises a flash read only memory (ROM), a chipset, an NFC module and a central processing unit (CPU). The flash ROM stores a basic input/output system (BIOS) having a default user identification (UID) and a default entry key data. The chipset comprises a keyboard buffer. The NFC module reads a UID seed from the NFC tag when the NFC tag is close to the NFC module. The CPU generates a current UID according to the UID seed and a function, and determines whether the current UID is equal to the UID. The CPU writes the default entry key data to the keyboard buffer if the current UID is equal to the UID.
