Production printed circuit boards (PCB) originally contained a potential current flow issue between the Front Panel LEDs and to the Super I/O controller.
Specifically, the front panel LED off of the Super I/O controller (SIO3 - silkscreen U2A2) was incorrectly set to operate at 50mA of current instead of operating at 15mA designed for the Super I/0 controller. This circuit was not initially connected correctly on all Fab6 production boards. In other words, the 220 ohm R1H9 resistor was not connected in series between pin 5 of the J1H1 connector and pin 50 of the National* SIO3 Super I/O chip. As a result, the circuit incorrectly allows 50mA of current to flow.
