Abstract: A method for managing power to an information handling system (IHS) is disclosed wherein the method includes providing a battery and an external power supply operable to supply power to the IHS. The method also includes providing an application programming interface (API) to the IHS, wherein the API is configured to monitor a first parameter and a second parameter. The method further includes supplying power to the IHS via the external power supply if the first parameter reaches a first threshold level and supplying power to the IHS via the battery if the second parameter reaches a second threshold level. An information handling system (IHS) is further disclosed including an external power supply, a battery, and a controller operable to select between the external power supply and the battery to supply power to the IHS.

Abstract: Methods and systems are disclosed for detecting DisplayPort (DP) source device connection to sink devices. When the DP link is active, no measurements are made to determine source device connections. When a DP link is not active, a signal line for the auxiliary channel for a DP connection is measured to determine if a source device is connected. More particularly, the auxiliary channel is a differential auxiliary channel, and the positive signal line is measured to make the determination of whether a source device is connected. Still further, an indication is made that a source device is connected if the positive signal line is at a low level, and an indication is made that a source device is not connected if the positive signal line is at a high level.

Abstract: A display system includes a display chassis defining a display chassis housing. A display panel is located in the display chassis housing. A power supply module chassis defines a power supply module housing and is coupled to the display chassis outside of the display chassis housing. A power supply module is located in the power supply module housing and coupled to the display panel. Such display system architecture allows the display chassis to be much thinner than conventional externally connectable display chassis.

Abstract: A display device includes a plurality of video input interfaces. The display device also includes a display controller coupled to the plurality of video input interfaces. The display controller determines a sequence in which the plurality of video input interfaces are scanned for a video signal. The display controller makes the determination in response to activity information associated with one or more video input interfaces included in the plurality of video input interfaces.

Abstract: An information handling system (IHS) stores display characteristics information of the last display coupled to the IHS prior to a boot or suspend/resume operation. Upon receipt of a boot or resume command, time is saved by the IHS using the last display characteristics information to activate the current display if the current display characteristics information is the same as the last display characteristics information. Otherwise, the display is reinitialized which consumes more time in the boot or resume process.

Abstract: The present invention employs two unique identification files associated with the same dual-interface display monitor. Each identification file identifies one of the display monitor's two interfaces, so that each identification file identifies the display monitor as a separate display monitor, with a unique product code and its associated characteristics, to the computer system. When an initiating event occurs, such as a power on self test, hot plug-in, or reboot, the monitor responds to a request for its identification file with the digital identification file if the monitor is connected to the digital video connector and with the analog identification file if the monitor is connected to the analog video connector. If both connectors are connected, the monitor with send the digital identification file as a default. In the preferred embodiment, the identification files are EDID™ files.
