My Auto Power On HP-32S

[Pjwum]

Quote:When this occurs, does it also clear the program memory and storage registers?

Thank you, Steve! Your questions brought me to the solution. No, it doesn't clear the memory. Just powers on and puts a zero on the stack. Battery power is ok and all keys function. In fact, the intervals between spontaneous power on got larger and the feature vanished after applying my wife's hairdryer.
Some moisture from cleaning the keyboard must have caused a shortage on the conductive foil.
I rather should have cleaned with some alcohol.
