Abstract: An information handling system detects whether there is a power loss from an alternating current power source. In response to detecting the power loss from the alternating current power source, the system transmits a power loss signal to a display device that is coupled to the information handling system, and provides auxiliary power to the display device during the power loss.

Abstract: An information handling system includes an embedded controller configured to transmit an error code to a pre-extensible firmware interface initialization module. A graphics font manager may generate a glyphs database during a boot process. If the error code is associated with a no power-on self-test, no video condition, then the pre-extensible firmware interface initialization module may retrieve information associated with the error code transmitted by the embedded controller, and locate the glyphs database generated by the graphics font manager from the non-volatile storage device.

Abstract: An information handling system touchpad includes an application area with a display to present control icons of an application executing on the information handling system, such as camera and microphone icons to control camera and microphone functions of a videoconference application. The touchpad dynamically adjusts touchpad display brightness and color based upon ambient light conditions detected by an ambient light sensor. Touchpad display brightness control is set independent of main display and keyboard backlight illumination brightness.

Abstract: An information handling system touchpad includes an application area with a display to present control icons of an application executing on the information handling system, such as camera and microphone icons to control camera and microphone functions of a videoconference application. A gesture at the touchpad in the application area commands presentation and removal of the control icons at the touchpad display in the application area while different touch analysis logic is applied to end user touches in the application area versus the remainder of the touchpad at which cursor inputs are accepted.

Abstract: An information handling system touchpad includes an application area with a display to present control icons of an application executing on the information handling system, such as camera and microphone icons to control camera and microphone functions of a videoconference application. The touchpad dynamically scales between a first configuration that accepts cursor inputs at the full touch detection surface area and a second configuration that limits cursor inputs to touches in a first portion of the touch detection surface and presents control icons in a second portion, such as by applying different touch analysis logic to end user touches in the first and second portions.

Abstract: An information handling system touchpad includes an application area with a display to present control icons of an application executing on the information handling system, such as camera and microphone icons to control camera and microphone functions of a videoconference application. A cursor touch rejection logic is applied at the touchpad to interpret touches as inputs to the information handling system based upon a presented cursor position. A separate application touch rejection logic is applied to the application area with the control icons are presented.

Abstract: A disclosed information handling system is configured to display a consistent logo or image throughout a platform initialization process. In a first-time boot, in a DXE phase, image information is read from firmware storage and processed for native resolution for a display panel and HOB information is saved to firmware volumes with Hand-Off Block (HOB) information. In subsequent iterations of the platform initialization process, the processed image is displayed early in a PEI phase and the HOB information is stored with the processed image. The image is displayed throughout the DXE and BDS phases of each subsequent platform initialization process and the display is consistent for different information handling systems and display panels.

Abstract: A record is maintained of cumulative erase operations performed at each block of a firmware flash memory device. It is determined that a number of erase operations performed at a first block at the firmware flash memory device exceeds a first threshold value. It is further determined that a number of erase operations performed at a second block at the firmware flash memory device does not exceed a second threshold value. Data stored at the first block is relocated to the second block.

Abstract: Systems and methods for providing technical support and exporting diagnostic data. In some embodiments, an Information Handling System (IHS) includes a processor; and a memory coupled to the processor, the memory having program instructions stored thereon that, upon execution by the processor, cause the IHS to: identify a video failure in response to executing a Basic I/O System (BIOS)/Unified Extensible Firmware Interface (UEFI) diagnostics routine prior to the booting of a main Operating System (OS), where the video failure renders the IHS incapable of providing a video interface; and in response to the identification, provide an audio interface to a user, where the audio interface enables the user to perform a troubleshooting operation in the absence of the video interface.

Abstract: A gesture-based method is disclosed for authenticating a user. More specifically, the user of an information handling system is prompted to enter a passcode finger tap sequence input gesture via a touch-sensitive device. The finger tap sequence input gesture is processed to generate a passcode finger tap sequence. The passcode finger tap sequence is then compared to a previously-generated authentication finger tap sequence. If the two finger tap sequences match, then the user is authenticated.
