Abstract: An information handling system includes a basic input/output system having a virtual advanced configuration and power interface device. A processor may download a device driver for a particular virtual advanced configuration and power interface device, wherein the device driver includes a code for a security feature and a signed file that includes a list of identifiers of compromised information handling systems. The processor may determine whether the information handling system is compromised based on the list of identifiers of compromised information handling systems in the signed file, and execute the code for the security feature.

Abstract: Methods and systems are provided that may be implemented to detect and capture information related to host system hang events which may occur during booted and in-band operation of an information handling system, e.g., for further analysis such as debugging. The disclosed methods and systems may be employed to monitor for behavior that is indicative of the occurrence of a host processing device system hang event that occurs while a host operating system is booted and running on the host processing device. Information regarding the nature and/or cause of a detected system hang event may be captured and stored for further analysis and/or for identifying a corrective action.

Abstract: Systems and methods are provided for creating and/or modifying memory configuration settings (e.g., such as memory timing and memory drive voltage) for use at selected and/or varying memory temperature/s. The disclosed systems and methods may be implemented to create a relationship between optimized memory configuration settings for different memory temperatures during burn-in testing and/or on an ad-hoc basis.

Abstract: A portable information handling system (IHS) is provided. The portable IHS includes a processor and a memory device coupled to the processor. The memory device is for storing instructions processable by the processor for determining whether a lid of the portable IHS is closed. Also, the instructions are processable by the processor for, in response to determining that the lid of the portable IHS is closed, determining whether the portable IHS is operating within a substantially sealed case. Moreover, the instructions are processable by the processor for, in response to determining that the portable IHS is operating within a substantially sealed case, reducing the portable IHS power consumption.

Abstract: A method and system for allowing a processor to enter low power states in an information handling system (IHS) include detecting an access request for a bus mastering device. The method and system also include in response to failing to detect an access request for the bus mastering device within a period of time, suspending a bus mastering device controller associated with the bus mastering device, wherein the now suspended bus mastering controller no longer prevents the processor from entering low power states.

Abstract: In response to an information handling system (IHS) being inactive, an instruction to place the IHS's processor in a low power state is generated. Also, in response to the instruction, a first value of an operational parameter of the processor is stored. Moreover, the operational parameter of the processor is modified to a second value so that the IHS consumes less power while the processor operates with the operational parameter that is modified to the second value. Further, in response to the IHS not placing the processor in a low power state within a predetermined time period, the operational parameter of the processor is restored to the first value.

Abstract: Information handling system functions performed with an information handling system operating system in a quiescent state, such as ROM flashing, diagnostics BIOS warning screens and hard disc drive backup, are supported through an operating system quiescent state initiated by a simulated power down state which leaves one or more processing components of the information handling system operational. For instance, an operating system utility sets a BIOS flag and pointer so that an ACPI S3 power down state places the operating system in a quiescent state but an S3 suspend call from the operating system is intercepted and a quiescent state function called by the BIOS. Recovery of the operating system from the quiescent state is initiated with the BIOS so that a reboot of the information handling system is avoided.
