| Symptom: In stand-by the current drawn from back-up battery is excessively high. Work-around: Put resistor in parallel to C94. Start with a value of 56k - this seems to work in most cases. If board does not start increase value slightly. | Symptom: In stand-by the current drawn from back-up battery is excessively high. Work-around: Put resistor in parallel to C94.
