An information handling system may include a strain force fuse formed on a circuit board of the information handling system, the strain force fuse configured to experience an impedance discontinuity in response to a mechanical force applied to the circuit board at or proximate to the strain force fuse and a management controller electrically coupled to the strain force fuse and configured to provide out-of-band management facilities for management of the information handling system, the management controller further configured to detect whether the impedance discontinuity has occurred.

Systems and methods for detecting mechanical strain on a circuit board

An information handling system may include a circuit board, an integrated circuit package mounted on the circuit board, the integrated circuit package comprising: a plurality of solder balls for electrically coupling the integrated circuit package to the circuit board, the plurality of solder balls comprising a first solder ball and a second solder ball, an internal electrical coupling coupled between the first solder ball and the second solder ball, and a management controller electrically coupled to the internal electrical coupling, the first solder ball, and the second solder ball, and configured to provide out-of-band management facilities for management of the information handling system, the management controller further configured to detect whether an impedance discontinuity has occurred with respect to one or both of the first solder ball and the second solder ball.

Systems and methods for detecting mechanical strain on a ball of a ball grid array

An information handling system implemented as a convertible notebook may include a first assembly, a second assembly hingedly coupled to the first assembly, a magnet housed in the first assembly, a giant magnetoresistance sensor housed in the second assembly, a Hall effect sensor housed in the second assembly, and a management controller communicatively coupled to the giant magnetoresistance sensor and the Hall effect sensor, and configured to, based on a first signal received from the giant magnetoresistance sensor and a second signal received from the Hall effect sensor, determine a position of the first assembly relative to the second assembly.
