All of a sudden my hp calculator won't add. Normally I'll press f CLX. Xy and it will clear. I've tried using - and off on. No luck, I've tried the penny in the battery no luck. I've tried a new battery. No luck. Next I'll take my battery out for 24 hours but then if it doesn't work I don't know what to do. Help! Mary B

Hi,

You have done everything I would normally recommend.

Do you have the HP-12c (gold bezel) or HP-12c Platinum (silver bezel)?

Hi,

 

If you have the HP-12C platinum, it has both Algebraic and RPN entry mode.

 

You may have been using it in the Algebraic mode and it is now in RPN mode or vice versa.

 

Regards.
