Abstract: Motherboard connector failures can be predicted. An embedded controller can be employed on the motherboard to monitor when devices are connected to and disconnected from the motherboard's connectors. The embedded controller can maintain an event log and connector information in which it counts the number of times a device is connected to/disconnected from a connector. The BIOS can leverage the event log and the connector information to notify an end user to take action to correct or prevent possible corrosion. Training records may also be employed to predict connector failure. The training records can track and maintain baseline and periodic device training attributes. When the periodic training attributes deviate from the baseline training attributes, an end user can be notified to take action to remove corrosion.

Abstract: A key-press detection circuit for an information handling system includes a detector circuit, a RC circuit, and a latch circuit. The detector circuit is coupled to a keyboard matrix device, and operates to provides a clock signal in a first state when a particular key of the keyboard matrix device is pressed and to provide the clock signal in a second state when the particular key is not pressed. The RC circuit receives the clock signal and provides a timed clock signal in a third state for a predetermined amount of time in response to receiving the clock signal in the first state. After the predetermined amount of time, the RC circuit provides the timed clock signal in a fourth state. The latch circuit receives the timed clock signal at a clock input, receives a data signal at a data input, and latches an output signal in a same state as the data signal when the timed clock signal changes from the third state to the fourth state.
