RE: HP30B retunrning to "default values"
Also the battery hatch design is sadly lacking. A. Good knock or rap on the calc will temporarily disconnect the power supply causing the default. The battery then returns to position and the circuit is complete leaving you with a functional but 'defaulted' condition.

This happened to me with the 34s conversions when it was in my flight bag which gets tossed around at airport security. Fixed it by folding some paper to fit between the battery and the rear sliding case which adds more pressure holding the battery in place during these transient jolts.
