A HP-41C (2 transistor version) shows "Memory Lost" continuously on battery insertion and does nothing else. Any clues for the clueless. It's not the easiest calculator to fault find :-)

First thing to check with this symptom is whether or not the ON key is shorted.

Second thing to check is the power connections. Battery block, springs in battery holder, CPU board connector. If the power is intermittent it can also cause this symptom.
