Abstract
A computing device includes a module that connects to a main board and a short detector. The short detector applies a voltage to a first electrical contact of the module; while the voltage is applied: makes a comparison of a second voltage on a second electrical contact of the module to the voltage; makes a determination, based on the comparison, that the first electrical contact is connected to the second electrical contact via a short circuit; and in response to the determination, initiates remediation of the short circuit.
Claims18
A computing device, comprising:
- a module adapted to connect to a main board;
- and
- a short detector adapted to:
- apply a first voltage to a first electrical contact of the module;
- and
- while the first voltage is applied:
- make a comparison of the first voltage to a second voltage on a second electrical contact of the module;
- make a determination, based on the comparison, that the first electrical contact is connected to the second electrical contact via a short circuit;
- in response to the determination, initiate remediation of the short circuit;
- and
- after initiating the remediation:
- make a second comparison of the first voltage to the second voltage;
- make a second determination, based on the second comparison, that the first electrical contact is no longer connected to the second electrical contact via the short circuit;
- and
- after making the second determination, continue the remediation of the short circuit.

A short detector, comprising:
- a voltage source adapted to apply a first voltage to a first electrical contact of a module during a short test;
- and
- a comparator adapted to:
- perform a comparison between the first voltage and a second voltage on a second electrical contact of the module;
- make a determination, based on the comparison, that the first electrical contact is connected to the second electrical contact via a short circuit;
- and
- in response to the determination, initiate remediation of the short circuit;
- and
- after initiating the remediation:
- make a second comparison of the first voltage to the second voltage;
- make a second determination, based on the second comparison, that the first electrical contact is no longer connected to the second electrical contact via the short circuit;
- and
- after making the second determination, continue the remediation of the short circuit.
