50g Random Turn ON

[DavidM]

I've never seen this occur with my 50g, nor did I ever see it with the 49g+ that I used before that.

I don't set alarms on my 50g, mainly because I can't count on them working. But I do wonder if the same issue that hampers the alarms from working properly is behind what you are seeing.

IIRC, all RPL-based calcs "wake up" when a particular timer reaches 0, though (in theory) this should only result in a visibly active system if an alarm was the reason that the timer hit 0. A non-alarm timer event of this type is supposed to immediately reset the timer and power down the CPU, without having activated the calculator's normal power-up sequence. Perhaps there's something about these particular systems that fools the code into thinking it should do a full power-up when that timer event occurs.

Since you are keeping logs of this, how often does it occur? Multiple times per week/day/hour? Just curious. In particular, what's the shortest period between unintended power-ups that you've seen?
