50g Random Turn ON

See the bug report here. The alarm issues are specific to the ARM-based systems, and at least one knowledgeable source has suggested that they may be a result of a problem with Kinpo's code. I believe there has been a subsequent posting in this forum from another knowledgeable source that questions if JYA's post is still relevant, but I haven't been able to find it.

While I definitely remember the alarm issues being discussed, this is the first thread I can recall that has mentioned the spontaneous power-up problem. That doesn't mean I doubt its veracity, though. What I am most curious about is how frequently the power-ups occur, and if there is some correlation between the power-ups and the "jitter" of the system clock in these ARM-based systems (which seems to vary with each individual calculator).

I've been running a logger on my daily-use 50g for several days now with no instances of unattended power-ups. Two other calcs (a newer 50g and a 49g+) are also equipped with the same software, but I'm leaving them on the shelf for a while before checking as I want to allow them plenty of idle time before disturbing them.
