Any info on how to test this calc "is it toast"? Specific: Tool Box, Prob,. Combo & Perm? Mine will not execute. Thanks in advance.

RE: HP Prime malfunction(s)
Um, any info that we can possibly understand?
You basically said "It bad. Why Bad?" TW Although I work for the HP calculator group, the views and opinions I post here are my own.

Attempting to compute a "combo or perm", I press, ON, Tool Box, 5, 2 and the display: "ERROR". Then I press OK and type "20,4" within the parenthesis: "ERROR:Syntac Error"

More frequent within the last few weeks than cumulatively over the many years that I have owned it.
Reset via "pin hole" on the back side. Thanks

Some folks prefer to use the comma "," symbol for their fraction mark, which usually then makes the semicolon ";" the separator symbol (in place of the comma). Graph 3D  QPI  SolveSys

Thank you, Hans:
I investigated my "settings" to discover that "RPN" is not acceptable as an "Entry" notation. Upon switching to Algebraic....all is well. again, thanks

Good Morning MFLEMING:
Very "thank you" to you. I prefer RPN, though my quest within this forum demonstrates my ineptness.
