PRIME Lockup after pressing Enter key in Solver. - Harold A Climer - 10-14-2013 I have written two equations in the Numeric Solver
I had unchecked the first two equations when I was entering the third equation in the symbolic menu. Re: PRIME Lockup after pressing Enter key in Solver. - Michael de Estrada - 10-14-2013 You can reset the calculator by inserting a pin through the small Reset hole in the back of the case. It should not delete anything.
Re: PRIME Lockup after pressing Enter key in Solver. - Tim Wessman - 10-14-2013 I tried to duplicate and was unsuccessful (worked fine). Some questions might be helpful.
1. RPN mode? Only thing to do is ON-APPS. If you hadn't turned the unit off before, then no, it has not been written out to flash and it may be gone.

Re: PRIME Lockup after pressing Enter key in Solver. - Harold A Climer - 10-14-2013 Quote:I was able to finally get it to reset using the ON key and Symb key combination found in the users manual. However the last equation I was trying to enter was gone as well as the three variables I had previously established. Glad I did not have to use the paperclip reset. Re: PRIME Lockup after pressing Enter key in Solver. - Michael de Estrada - 10-14-2013 Where did you find this in the Users Guide ? Is there a separate User Manual that I don't know about ?
Re: PRIME Lockup after pressing Enter key in Solver. - Marcus von Cube, Germany - 10-14-2013 In the emulator install directory you'll find HP_Prime_User_Guide_EN.pdf. Look for "Reset" or "Troubleshooting" or go directly to page 597 in Acrobat Reader.
Re: PRIME Lockup after pressing Enter key in Solver. - Michael de Estrada - 10-14-2013 It's not on my CD, just the Quick Start Guide.
Re: PRIME Lockup after pressing Enter key in Solver. - Marcus von Cube, Germany - 10-14-2013 Install the software and look on your disk!
Re: PRIME Lockup after pressing Enter key in Solver. - Michael de Estrada - 10-14-2013 I already did that. I found a User Guide that stops at page 549 !
Re: PRIME Lockup after pressing Enter key in Solver. - Jonathan Cameron - 10-14-2013 You can find the July 2013 version of the User Guide at http://www.hpcalc.org/ in the new Prime section (click on the "Documentation" link there). It has 616 pages.
Re: PRIME Lockup after pressing Enter key in Solver. - Michael de Estrada - 10-14-2013 Yes, I already have that latest version, but it lacks the info that is described in this thread. It may have been in the earlier May version, and then removed.
Re: PRIME Lockup after pressing Enter key in Solver. - Michael de Estrada - 10-14-2013 OK, the mystery is solved. There are two versions of the Users Guide: Version dated May 2013 - Located in Emulator install directory of computer hard drive. Contains an Appendix B - Troubleshooting that begins on page 531, and discusses various key sequences to achieve a reset or restore of default settings. No mention of reset button on back of calculator.
Version dated July 2013 - Downloaded from online links. Contains an Appendix B - Troubleshooting that begins on page 591 and contains only a description of how to reset the calculator via the reset button on the back of the calculator.

Here is the text
If the calculator does not turn on 1. Press and hold ON for 10 seconds, then release.
NOTE This is where the second key to press is not obvious
2. Press and hold On and ?simultaneously ?, then Re: PRIME Lockup after pressing Enter key in Solver. - Michael de Estrada - 10-14-2013 I think ? is the spacebar key between to the . and + keys.
