50g Random Turn ON

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.

I've wondered myself if it's a problem with the Kinpo code or if it could be even an unfixable fault in the hardware design (though hopefully not!).

One mysterious issue I've always had myself which I feel might also be related, but never heard anyone else mention, is occasional, complete spontaneous lockups while the calculator is on but the CPU is in idle state. This happens randomly to me, roughly every several weeks or months or so. I've never been able to find any pattern at all. The calculator becomes completely unresponsive to keys (including ON+C), and I'm forced to remove and reinsert a AAA battery to force a warm start. I've never lost Port 0 or HOME when this occurs, but losing the unsaved work in an ongoing editing session or stack calculation still isn't too funny.

There's also the “busy bug”, where pressing a key just as the CPU is going into idle causes the key to be ignored, only to then be processed as soon as another key is pressed. It is impossible for me to go a single day of normal 50g usage without this happening more than once.

It's frustrating for HP never to have done anything about such intrusive issues; it really blemishes an otherwise excellent and reliable product. But now I'm bordering on rant mode, so I'd better stop.
