HP-12C Platinum won't turn off after screen self-test
I did a screen self-test (X + ON) on my 12C and 12CP then I left my desk, thinking that they will turn off automatically.
A couple of hours later I come back and at my surprise, the screen of the 12C Platinum still remained on with all segments visible. BTW, the other 12C did turn off as expected. So was it a bug or a feature?  ![[Image: IMG-20231128-002152.jpg]](https://i.ibb.co/BnszvMk/IMG-20231128-002152.jpg)
