  • Patent number: 8250387
    Abstract: A portable computer having a biometric authentication device is disclosed. The portable computer also includes a processor, a power supply unit having a first power system and a second power system, a power control circuit for controlling the power supply unit, and a start-up button for generating a startup signal for starting the portable computer. The biometric authentication device sends a power request signal to the power control circuit to activate the second power system upon a detection of a human user in a state where the second power system is deactivated and electric power is being supplied by the first power system. The biometric authentication device can perform an authentication operation while receiving electric power from the second power system, and the power control circuit causes the portable computer to transition to a power-on state in response to an authentication success by the biometric authentication device.
