Abstract: Systems and methods that may be implemented to employ a programmable integrated circuit within a smart battery pack to detect and/or log occurrence of chassis intrusion and/or tampering events in a battery-powered information handling system within which the smart battery pack is installed. A battery management unit (BMU) or other programmable integrated circuit of the installed smart battery pack may be utilized to detect occurrence of a tampering and/or intrusion event into the chassis of the host information handling system based on a current state of a system present (Sys_Pres) signal at the battery pack that indicates temporary or permanent disconnection of system motherboard circuitry from the smart battery pack of the battery-powered information handling system. Such a detected occurrence of a tampering and/or intrusion event may be reported to a remote human user of remote system and/or to a local human user of the local system.

Abstract: In one or more embodiments, an information handling system may determine that a housing is in contact with the information handling system that is operating with a first operating profile. For example, the housing may be or include a case or a cover. In response to determining that the housing is in contact with the information handling system, the information handling system may determine a second operating profile of the information handling system that increases a processing speed of at least one processor of the information handling system. In one or more embodiments, the second operating profile may be or include a thermal profile that permits the information handling system to have an increased skin temperature of at least a portion of the information handling system. In one or more embodiments, the information handling system may operate based at least on the second operating profile.

Abstract: An information handling system allocates power for internal use and to support peripheral device operations by managing bi-directional power transfer at plural cable ports. A user interface presents to an end user the detected power transfer states and alternative states for alternative power and data transfer rates with changed cable and port connections. The user interface provides users with real time information for power and data transfer configurations that help optimize information handling system performance.

Abstract: A security lock is provided for a mobile device. The security lock includes a pair of locking elements and a pair of electromechanical actuators. Each locking element has a profile configured to complement a profile of a locking tab of an external locking assembly. Each electromechanical actuator is configured to engage an associated one of the locking elements to lock the locking tab to the mobile device, and to disengage the associated locking element to unlock the locking tab.

Abstract: A system, method, and computer-readable medium for performing a chassis intrusion operation. The chassis intrusion operation includes monitoring an information handling system for occurrence of an intrusion event, the monitoring being performed whether the information handling system is in a powered on state or a powered off state; providing information regarding the intrusion event to a chassis intrusion system, the chassis intrusion system identifying a remediation action to perform in response to the intrusion event; and, performing the action on the information handling system, the remediation action remediating the intrusion event.

Abstract: The present disclosure provides various embodiments of an external power supply and methods to enhance the output power delivered by an external power supply to a power consuming load. As described in more detail below, the embodiments disclosed herein enable an external power supply to deliver a higher than maximum output power for short periods of time when ambient temperatures within the external power supply are low. As the ambient temperature increases, the embodiments disclosed herein throttle (or incrementally reduce) the output power delivered by the external power supply until the maximum output power specified for the power supply is reached. Although not strictly limited to such, the external power supply may be a Universal Serial Bus (USB)-enabled AC/DC adapter, and more specifically, a USB Power Deliver (USB-PD) AC/DC adapter, in some embodiments.

Abstract: An information handling system with multiple power input ports, such as USB ports, capable of receiving power from external power supplies may control power received from the power supplies. A first controller may detect a first power supply coupled to a first power input port of the system and may allow power to flow from the external power supply to the system. Any additional power supplies detected by controllers may be blocked from providing power to the system while the first power supply is providing power.

Abstract: Systems and methods are provided that may be implemented to provide a power supply with automatic overcurrent protection (OCP) point calibration and/or current sense resistor (Rsense) verification. The provided systems and methods may implement auto-calibration techniques on the secondary side of a power supply to achieve a more precise OCP point than is possible with conventional adapter technology, and in one example may implement auto trimming for OCP voltage threshold value.

Abstract: An information handling system receives power from a reversible power cable by selectively configuring outer pins to provide power or communication with a middle pin providing ground. A power manager of an information handling system embedded controller uses a low level of power input to determine which outer pin provides power and which provides communication, and then configures the connector to route power at a high level to the system charger for powering the information handling system.
