Abstract: In one implementation, a printed circuit board (PCB) includes a plurality of pads that form a pad pattern on the PCB. In that implementation, the plurality of pads include a group of load pads, a dummy pad, and a false pad. The group of load pads act as contact points to establish an electrical path between a first circuitry and a second circuitry. The dummy pad is coupled to a via that floats electrically and the false pad is coupled to a third circuitry.

Abstract: An example device includes a physical interface to connect to a system. The device also includes a power source to deliver power to a diagnostic portion of the system via the physical interface. The diagnostic portion draws a small amount of power. The power source delivers the power based on the system not receiving power from an internal source. The device also includes a reporting engine to communicatively couple to the system via the physical interface. The reporting engine retrieves an indication of whether a cable in the system is connected.
