Sorry Dan, on the 12c Platinum you can toggle from RPN to ALG mode by pressing the [f] [EXX] keys.
In reply to Dan:
Does anyone know how to turn off the RPN on my HP12c - not sure if this function is the issue but cannot enter a calculation - just keeps adding numbers to the registry,
Thanks,
Dan

My 12c wouldn´t turn on. At first I merely jumped the paper clip between the spring and the opposite terminal and nothing happened. But, when I stuck one straightened end of the clip through the spring all the way to the terminal and wedged the other rounded end of the clip to the opposite terminal, Vuela, it worked.
Thanks a bunch!

HI, What is Capacitor discharge and how do u make this trick work, strugling with clearing functions or something else.
Thank you, Namak
In reply to Jeff:
Thank you very much. My 12c has been around longer than my kids and twice as useful. I was concerned I would have to go out and get a new calculator that would only be half as good.
Capacitor discharge did the trick.

Hi Bill, sounded like the LCD is damaged. I don´t think it can be repaired as the LCD panel is soldered to the main logic board.
In reply to Bill:
I only found 1 battery. I tried reset but was not sure where terminals were. Reset did not fix problem. My problem is that when I enter .80 the display shows 8.0. Any ideas

Thank you very much! After replacing batteries the display showed something like arabic script and wouldn´t function at all. Discharging the capacitor worked like a dream. And to think I was ready to toss the 12C I love so much.

Hi Guys,
This may be a stupid question, but what is the safest and most reliable way to get that battery out? I tried pulling it out with my fingernails, but was unable to do so, and am reluctant to use more tools or force for fear of damaging the calculator. Do I have to press down on some side or what?

This site was great. I could not remove a comma to replace with decimal. With the search function, we received the instructions with minutes and was able to fix. I thought I needed new batteries.

Push the yellow function key and the number key corresponding to the number of places you want to the right of the decimal at the same time.
In reply to NS:
how do you set the decimal point to read 3 digits to the right?
