In a computer, the Advanced Configuration and Power Interface (ACPI) provides an open standard that operating systems can use to discover and configure computer hardware components, to perform power management by (for example) putting unused components to sleep, and to perform status monitoring. First released in December 1996, ACPI aims to replace Advanced Power Management (APM), the MultiProcessor Specification, and the Plug and Play BIOS (PnP) Specification. ACPI brings the power management under the control of the operating system, as opposed to the previous BIOS-centric system that relied on platform-specific firmware to determine power management and configuration policies. The specification is central to the Operating System-directed configuration and Power Management (OSPM) system, an implementation for ACPI which removes device management responsibilities from legacy firmware interfaces via a UI.
Systems and methods for injecting an overlay into a video framebuffer memory by a basic input / output system (BIOS) without triggering a host operating system (OS) exception
PendingUS20250383893A1Digital data processing detailsBootstrappingOverlayAdvanced Configuration and Power Interface
Systems and methods for injecting an overlay into a video framebuffer memory by a Basic Input / Output System (BIOS) without triggering a host Operating System (OS) error. An Information Handling System (IHS) includes a processor and a memory coupled to the processor. The memory stores program instructions that, upon execution, cause the processor to receive a command from an Embedded Controller (EC) and create an Advanced Configuration and Power Interface (ACPI) table with a video framebuffer memory location usable to store an overlay. The EC issues the command in response to the IHS returning from a selected power state or determining that the IHS is in a selected posture. The overlay may include a software keyboard icon or an Original Equipment Manufacturer (OEM) splash screen. The host OS checks the ACPI table during boot and allows the BIOS to write to the video framebuffer memory location without triggering an error.

Systems and methods for cross operating environment diagnostic operations with context resume
ActiveUS20250384137A1Platform integrity maintainanceAdvanced Configuration and Power InterfaceOperational system
Systems and methods for cross operating environment diagnostic operations with context resume. An Information Handling System (IHS) includes a processor and a memory coupled to the processor. The memory stores program instructions that, upon execution, cause the IHS to receive a command at a Basic Input / Output System (BIOS) from an Embedded Controller (EC) to perform a deep scan diagnostic operation. The command is received in response to a request by a host Operating System (OS) application. The BIOS executes the deep scan diagnostic operation and stores the result in an Advanced Configuration and Power Interface (ACPI) table. The host OS retrieves the result from the ACPI table and validates the result. The system enables comprehensive diagnostics by leveraging the BIOS environment, ensuring seamless context resume.

Systems and methods for handling platform-agnostic pre-boot health information in an information handling system
ActiveUS20250362925A1Detecting faulty hardware by power-on testHardware monitoringAdvanced Configuration and Power InterfaceOperational system
Systems and methods for handling platform-agnostic pre-boot health information in an Information Handling System (IHS) are described. In an illustrative, non-limiting embodiment, an IHS may include a processor; and a memory coupled to the processor, the memory having program instructions stored thereon that, upon execution, cause the IHS to: create an Advanced Configuration and Power Interface (ACPI) table, by a Basic Input / Output System (BIOS) during boot of the IHS, wherein the ACPI table comprises telemetry data and an identifier; and provide the ACPI table to an Operating System (OS) application, wherein the host OS application is configured to select one of a plurality of parsers to process the ACPI table based, at least in part, upon the identifier.

Thermal zone controls based on information handling system (IHS) posture in heterogeneous computing platforms
ActiveUS12613559B2Digital data processing detailsComputational scienceAdvanced Configuration and Power Interface
Systems and methods for thermal zone controls based on Information Handling System (IHS) posture in heterogenous computing platforms are described. In an illustrative, non-limiting embodiment, an IHS may include: a heterogeneous computing platform having a plurality of devices; and a memory coupled to the heterogeneous computing platform, where the memory comprises firmware instructions that, upon execution by at least one of the plurality of devices, causes the at least one device to operate as an orchestrator configured to: detect a change to an IHS posture; and in response to the detection, modify an Advanced Configuration and Power Interface (ACPI) thermal zone setting.

Performance optimizer for undersized power adapters
An information handling system, comprising an embedded controller configured to remove a first power setting of the information handling system in response to a determination that a power adapter plugged in the information handling system is undersized. The embedded controller is further configured to determine a second power setting based on a power rating of the power adapter and transmit an advanced configuration and power interface (ACPI) command to a basic input / output system (BIOS) to set the information handling system to the second power setting. The BIOS is configured to determine an offset value for a total graphics power based on the power rating of the power adapter subsequent to receipt of the ACPI command and notify a graphics processing unit of the offset value.
