First Claim
Patent Images
1. An information handling system for detecting failure of a hardware component 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 hardware component;
a sensor positioned within the hardware component for detecting an acoustic property of a hardware component in an information handling system;
where the program code comprises a diagnostics module for analyzing the detected acoustic property and issuing a hardware component failure signal based upon the detected acoustic property.

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.

10. A method for diagnosing hardware component failure, the method comprising:
-
initiating diagnostics on an information handling system to determine a hardware component failure;
activating the hardware component using a control sequence;
detecting audio signals generated by the activated hardware component to generate a first audio profile;
comparing the first audio profile to at least a first predetermined audio profile to determine if there is a hardware component failure. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. An apparatus for providing detection of drive failure, comprising:
-
a drive;
a sensor positioned to detect electromagnetic signals generated by operation of the drive;
a controller coupled to the sensor for creating a first profile based upon the detected electromagnetic signals, comparing the first profile to a reference profile to detect drive failure based on the comparison and generating a drive failure signal. - View Dependent Claims (18, 19, 20)
