A mainboard device and an update method of the basic input-output system thereof are provided. The mainboard device includes a flash memory, a universal serial bus (USB) port, and a microprocessor. The code of the basic input-output system is stored in the flash memory. The USB port is connected to an external USB device, wherein the external USB device includes a supply power and stores an update code. The microprocessor includes a power-switching device coupled to the system power and the USB port. When the power-switching device detects that the system power does not provide power and the USB port is provided with the supply power, the microprocessor provides power to the flash memory based on the supply power, and the microprocessor accesses the update code of the external USB device to perform an update operation on the code in the flash memory.
