HP-12C Platinum power - AnnoyedOne - 09-04-2024 12:31 PM

While looking on eBay I came across this "Made in Philippines" HP-12C Platinum made in 2007/2017 (the serial number also starts with PHA7).

[attachment=13903]

What is interesting (to me) is the orange (f) "OFF" label above the ON key. I'd never noticed that before.

So my questions are:
  • Is this a "Made in Philippines" thing?
  • Does one have to press f+ON to turn the unit off or is the the ON key a power toggle (per the 12CP manual* and HP-12C's)? I've seen one eBay listing for a 12CP claiming that it "won't turn off".

I know that the ON key on my HP-20S is not a power toggle and yellow+ON must be used to turn it off**.

Personally I never notice that [f] OFF on top of the [ON] key before.

I just toggle the [ON] key for On and Off all the time without any problem.

I did press the [f] OFF and its turn off as well.

That also works on my (1982) HP-15C, (1985) HP-16C, HP-12C+ (2022). I didn't try my HP-15C CE (2023). None have an OFF label. Weird.

Perhaps just there to let users know that it works.

I've done a bit more research on this. I did find a post, on Reddit, asking the same question. That said the answer remains unknown.

I still ask "why?".

It could be purely cosmetic or have some (yet to be discovered) undocumented function.

PS: It seems (from photo's online) that all Platinum's/Prestige's have the "OFF" label but the yellow/gold lettering makes it harder (for me) to see. The "Made in Philippines" units orange colour lettering stands out more.
