50g Random Turn ON

I have two HP 50g's (one since 2009 and one since 2012), and I've never known either of them to turn themselves on nor make any beeps in the process. I have, though, always experienced the buggy alarm/clock/keyboard/interrupt-handling behavior DavidM mentions, which has always been extremely irritating, but I've never heard of a real fix for it.

Could the calculators which do this have any libraries installed that might possibly be modifying the behavior of a “stock” HP 50g? Could they have a particular ROM version or range of versions in common?

The "beeping" discussed above only occurs because my STARTOFF object (which is run when the 50g times-out and powers-off) contains some BEEP statements. So the 50g turns-itself on (I suspect due to the buggy clock issues you referenced) at various times, and then when it times-out and powers-off, STARTOFF executes, plays the BEEP sounds and shuts down.

Your 50g almost certainly turns-on at random times like every other 50g, but you never notice it as it quietly turns-off a minute later.

To verify this, create a STARTOFF object in HOME, containing BEEP commands (I suggest several, as one is easy to miss) and then just set it aside and within a few days you will notice it too beeps.

The most popular 50g STARTOFF tune is listed above - try that one (It runs on about 8-10 50g's I'm aware of - darned unlikely there are more 50g's playing any other tune).
