A system, method, and computer-readable medium are disclosed for automatically allocating resources to a virtual machine. Expected workload profile data and application utilization data corresponding to a software application associated with a virtual machine (VM) is collected by an application profiling agent. Resource utilization data corresponding to the utilization of resources associated with the execution of the software application is collected by a system resource monitor. The expected workload profile data, the application utilization data, and the resource utilization data are then processed to determine a virtual machine workload class, which is then used to determine a corresponding VM policy. Data associated with the VM policy then processed to generate VM resource allocation instructions, which are in turn processed to provision the VM.

A modular display system and method assembles an external interface module with a display module to support built-to-order display configurations. The display module has display panel, timing controller and speaker components assembled in a display module housing that accepts a single LVDS and a single audio interface. The external interface module couples to the display module housing to form an integral display system. Selective assembly of the display system from plural types of external interface modules allows selective configuration of the display system with various television and information handling system display functionalities, such as to fill a purchaser order in a build-to-order manufacturing process.

Methods and systems for providing embedded user authentication and/or providing computing services using an information handling system configured as flexible computing node, and which may be implemented to perform preboot authentication of users. The flexible computing node may also be configured to provision the appropriate work environment for a given user based on one or more user parameters (e.g. entitlements, location, network connection, and/or other parameters).

An audio amplifier configuration for a personal computer system optimizes performance in both the single-ended mode and the bridged mode. In a single-ended mode, as when the computer system user receives audio through headphones plugged into an external jack, a jack sense line is activated that switches into operation a power supply that is optimized for single-ended audio operation. In the bridged mode, as when the computer user receives audio from the system's internal speaker, operation is such that the audio amplifier is supplied by a power source optimized for operation in a bridged mode. In general, single-ended operation dictates that the audio amplifier power supply exhibit substantial noise immunity characteristics; whereas bridged-mode operation requires that the power supply be capable of supplying more demanding peak voltage and current excursions.

Power supply noise immunity for audio amplifier

A speakerphone of a system with a digital signal processor, such as a computer, uses a filter set or network to provide acoustic coupling loss at a microphone to offset acoustic coupling gain produced by sound reflections resulting from various conditions in the system. The filter network processes an acoustic signal before the signal is provided to a digital signal processor to eliminate acoustic coupling gain that the digital signal processor is unable to cancel or offset. The filter network detects when the acoustic coupling gain in the acoustic signal at the microphone exceeds the maximum amount of acoustic coupling loss supplied by the digital signal processor. Alternatively, if acoustic coupling gain is desirable at the frequency location of the anomaly caused by the sound reflections, the filter network is used to boost the acoustic coupling gain produced by the anomaly. Thus, the present speakerphone uses equalization at the microphone to boost or attenuate acoustic coupling gain caused by frequency anomalies before acoustic echo cancellation by the digital signal processor.

A method and apparatus for controlling acoustic gain during a non-speakerphone audio mode of computer system independent of acoustic gain during a speakerphone mode of the computer system is provided. The BIOS code of the computer system detects whether the computer system is in a speakerphone mode or a non-speakerphone audio mode. If the computer system is in a speakerphone mode, an upper gain limit is not applied to the microphone path of the computer system. If the computer system is in a non-speakerphone audio mode, a predetermined upper gain limit is applied to the microphone path of the computer system. The predetermined upper gain limit is preferably applied to the microphone path at either a microphone pre-amplifier or an audio mixer chip in the microphone path of the computer system.
