50g Random Turn ON

[TravisE]

Oh, I see. This is interesting. Since I don't consider the beeper loud enough in my 50g's, I'd probably just set up a logging program. But it turns out that I essentially already have one: I've always had both calculators set up to automatically back up the HOME directory to SD card on every auto-off (with timestamps encoded into the filenames, along with an “auto-off vs. manually-invoked” flag), giving me a way to go back and track such events.

My daily-use 50g doesn't show anything suspicious yet for this month and last month. However, my older 50g (not used much anymore lately) does show about a half-dozen auto-off backups from last month as well as one for this December (the last three days), during which I'm pretty sure I wasn't using it.

So it seems like it really is happening. Given the amount of use I've given them, I would have expected to have noticed it myself long by now.
