Abstract: A computer-implemented method provides power to a fingerprint reader while the remaining components of the information handling system are held in a low power, non-operating state. Placement of a finger across the fingerprint reader is detected with the information handling system in the non-operating state. A fingerprint is read and a corresponding fingerprint image is generated. The fingerprint image is buffered and an embedded controller is triggered to start an authentication device having a secure storage. The fingerprint image is compared to a fingerprint template contained in the secure storage. In response to the fingerprint image matching the fingerprint template, the authentication device signals the embedded controller to activate a user authenticated wake-up cycle to provide power to the other components of the information handling system such that the information handling system activates an operating system and enters a fully powered and user authenticated, operational state.

Abstract: A docking station connects through a docking port and docking cable with an information handling system to support communication between the information handling system and docking station peripherals. The docking cable includes an integrated input device, such as a mechanical button or fingerprint scanner, which accepts an end user input to command a power state transition at the information handling system, such as a transition between an on state and a reduced power state. The power state transition is sent directly from the integrated input device to the information handling system or, alternatively, from the integrated input device to the docking station and then from the docking station to the information handling system.

Abstract: An information handling system inverter powers a display backlight at variable brightness levels determined by a brightness module integrated in the inverter. The brightness module sums a user interface setting, automated brightness setting and ambient light sensor measurement input into the inverter to determine the inverter power output, thus simplifying the integration of user brightness settings with automated brightness adjustments, such as DPST adjustments. A brightness range register holds maximum and minimum brightness settings for output by the brightness module. A calibration register holds a calibration brightness setting for calibration of display brightness.

Abstract: A clock diagnostics module, such as a state machine, integrated into an integrated clock controller monitors clock signals associated with the integrated clock controller and reports the status of the clock signals through a management bus, such as an SMBus. For instance, a counter integrated into the integrated clock controller counts clock signal cycles that occur in a management bus cycle and compares the clock signal with an expected value to determine the accuracy of the clock. A power on reset allows the management bus to read the clock diagnostics module in the event of clock controller failure.

The system includes a processor coupled to the protection circuit. The circuit is operative in a first mode to decouple an information line from the IHS in response to a disable command and operative in a second mode to decouple the information line from the IHS when a voltage in the information line exceeds a predetermined threshold voltage.

The secondary smart battery having a sufficient amount of the electrical energy is housed in a removable media of the device and is selectively discharged in response to a loss of an AC power source providing the electrical energy to the device. The primary smart battery having a sufficient amount of the electrical energy is then discharged in response to the discharging of the secondary smart battery to a threshold level. The primary smart battery continues to provide the electrical energy upon removal of the secondary smart battery from the removable media.

Abstract: A method and system determines the status of an external power supply connection to an information handling system. A subsystem manager of the information handling system compares an external power source identification signal and a power available signal to determine whether external power is available, unavailable or faulty. For instance, an information handling system configured as a portable computer receives external power from an AC/DC converter along with an identification signal for the converter. A state machine running on the portable computer system's Super I/O compares the identification signal and a power available signal from an internal charger to determine state of the external power source and indicate the state to a user.

In one embodiment, the circuit includes a signal generator for generating a square wave signal that varies in magnitude between a first voltage and a second voltage, and a voltage regulation circuit. A duty cycle of the square wave generated by the signal generator varies according to a signal provided to the signal generator. The voltage regulation circuit, coupled to the signal generator, outputs a DC voltage in response to the circuit receiving the square wave signal. The magnitude of the DC voltage varies between the first voltage and a third voltage, wherein the third voltage is greater than the second voltage, and wherein the magnitude of the DC voltage varies directly with the duty cycle of the square wave signal.
