摘要:
Power usage of computing device components is controlled in a holistic manner. The projected total power consumption for the computing device to satisfy a power consumption policy for the device is determined. Power usage of each component of the computing device is controlled in a holistic manner—i.e., balancing the power usage of the component against the power usage of other components—so that the total power usage of the computing device falls within the projected total power consumption needed to satisfy the power consumption policy. How the user is currently utilizing the computing device may be periodically detected, based at least on a power consumption distribution of the components of the computing device. A current usage model is determined based on how the user is currently utilizing the computing device. The power usage of each component of the computing device is controlled based on the current usage model.

An information processing apparatus is provided, which includes: plural devices, each having a high-power mode as an operation mode in which power consumption and processing speed are high, and a low-power mode as an operation mode in which power consumption and processing speed are lower than the power consumption and processing speed of the high-power mode; a measurement unit which measures temperature of a predetermined measurement point; a device selection unit which selects a device to be minimized degradation in processing performance when an operation mode is changed from the high-power mode to the low-power mode to lower the temperature of the measurement point in a case that the measured temperature is equal to or higher than a predetermined reference temperature; and an operation mode setting unit which changes the operation mode of the selected device from the higher-power mode to the lower-power mode.

A optical disc drive is disclosed. The optical disc drive includes a housing and a tray configured to accommodate a disc therein. The optical disc drive also includes an automatic return-type eject switch, a drive controller, and an eject controller. Mounted in the housing, the automatic return-type eject switch is configured to generate an eject signal. In response to the eject signal, the drive controller ejects the tray. In response to the eject signal, the eject controller supplies an electric power to the optical disc drive, and transmits a pseudo eject signal to the drive controller to eject the tray by way of a line through which the eject signal has been transferred after a predetermined time period from the supply of the electric power has lapsed.

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.
