Publication number: 20070168763Abstract: Information handling system errors are presented at a display with the information handling system graphics subsystem inoperative by communicating an identified error to the display through an auxiliary channel and generating a presentation of the error information with a microcontroller of the display. For example, errors determined by BIOS firmware running on a chipset are communicated through a DDC or I2C channel from the chipset to the display so that textual error messages are generated at the display without the use of the information handling system's graphic processor to generate an error message image.Type: ApplicationFiled: December 9, 2005Publication date: July 19, 2007Inventors: William Sauber, Rocco Ancona, Muhammed Jaber, Bruce Miller, Adolfo Montero, Margaret Reed-Lade, Jeff Rose, Andrew Sultenfuss, Larry White

Publication number: 20070106913Abstract: A technique is disclosed for utilizing power provided from a data communication line for operation of an information handling system. The power from the data communication line may be utilized even when the information handling system being powered requires more power than is available from the data communication line. More particularly, power management techniques are provided that couples the power from a data communication line to the power systems of the information handling system. The information handling system may include a plurality of power sources of which the data communication line power is just one such source. Power management circuitry identifies and characterizes the power available from the data communication line and integrates the power with the power available from other power sources. In one embodiment the data communication line may be an Ethernet connection that operates in accordance with Power Over Ethernet standards.Type: ApplicationFiled: November 7, 2005Publication date: May 10, 2007Inventors: Jonathan Lewis, Andrew Sultenfuss

Publication number: 20070054618Abstract: Wireless access points integrate building functions for improved building safety and reduced building wiring. A battery associated with a wireless access point is charged using power from a Power over Ethernet cable. The battery supports functions of the wireless access point and one or more building devices in the event of a power failure, the building devices communicating information through the wireless access point. For instance, emergency lighting and textual lamps are illuminated with the battery in the event of a power outage. As another example, fire sensors, fire alarms and intercoms provide emergency workers information and voice communication regarding the area within the proximity of a wireless access point to aid in rescue or fire fighting efforts.Type: ApplicationFiled: September 8, 2005Publication date: March 8, 2007Inventors: Jonathan Lewis, Andrew Sultenfuss

Publication number: 20060276988Abstract: 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.Type: ApplicationFiled: June 6, 2005Publication date: December 7, 2006Inventors: Andrew Sultenfuss, Christian Critz

Publication number: 20060277401Abstract: Interoperable firmware for an information handling system supports embedded controller and chipset operations from a common SPI flash ROM. The embedded controller is disposed between the chipset and the flash ROM with a pass through port integrated in the embedded controller selectively providing primary access to firmware by the chipset or the embedded controller. The pass through port provides chipset access to firmware without inducing delays for normal system operations, yet provides an integrated switch for control and access of the firmware by the embedded controller for updating of firmware settings and firmware diagnostics. Application of power to the embedded controller allows access to chipset firmware even where the chipset lacks power, such as during manufacture of the information handling system.Type: ApplicationFiled: June 6, 2005Publication date: December 7, 2006Inventors: Andrew Sultenfuss, Ronald Shaw

Publication number: 20060274023Abstract: 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.Type: ApplicationFiled: June 6, 2005Publication date: December 7, 2006Inventors: Andrew Sultenfuss, Christian Critz

Publication number: 20060108982Abstract: In a method and system for protecting a battery being charged by an electrical device, a current flowing through a cell stack of the battery is measured. If the measured current is greater than a predefined value the battery is isolated from the device. If subsequent current measurements made within a predefined time interval indicate that the measured current is less than or equal to the predefined value then the battery is recoupled to the device. If the measured current remains greater than the predefined value during the predefined time interval then a fuse is blown and the battery is disabled.Type: ApplicationFiled: November 24, 2004Publication date: May 25, 2006Applicant: Dell Products L.P.Inventors: Youssef Daou, Andrew Sultenfuss
