Abstract
Hardware component performance in an information handling system is detected with an integrated acoustic power spectra sensor that can be used for diagnostics analysis. The acoustic power spectra data is compared to acoustic models for operative drives to determine an acoustic pass/fail criteria, or to provide more sophisticated analysis of the drive performance, including specific drive failure conditions or impending drive failure conditions.

21. An information handling system for detecting a hardware component failure in the information handling system, comprising:
-
a processor;
memory interfaced with the processor;
program code stored by the memory and executable by the processor;
a plurality of hardware components; and
a sensor positioned within each of the plurality of hardware components, where each sensor detects an acoustic property of a hardware component in which the sensor is positioned;
where the program code comprises a diagnostics module for analyzing a detected acoustic property from at least a first sensor and issuing a hardware component failure signal for a hardware component associated with said first sensor based upon the detected acoustic property. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29)

30. A method for diagnosing hardware component failure in an information handling system comprising a plurality of hardware components, the method comprising:
-
initiating diagnostics on an information handling system to determine a hardware component failure;
activating a plurality of hardware components in the information handling system using a control sequence;
detecting audio signals generated by the activated plurality of hardware components using a plurality of sensors, each of which is positioned to be integrated within a corresponding hardware component, to generate a corresponding plurality of audio profiles; and
comparing each of the plurality of audio profiles to at least a first predetermined audio profile to determine if there is a hardware component failure in one or more of the plurality of hardware components. - View Dependent Claims (31, 32, 33, 34, 35, 36)
