When I turn on the 50g, it says "HP 49 CAS by Parisse, Heiskanen &
Fiechter" and won't let me do anything. If I reset it on the back, I
get the same message. If I do a 3-key clear memory without restore, I
get the same message. If I empty all the batteries and plug into the
USB I get the same message. Is this calculator toast?
