RE: HP80 Classic
I suspect the bad solder joint was the primary cause of the calculator turning off while being used, but the plastic film interfering with the on/off switch made the slide switch unreliable.
It was surprising how little dirt and debris made it into the calculator - my HP80 was most likely a treasured possession and treated kindly.
