HP 15C LE On/X ? - Matti Övermark - 08-10-2012 I am now an owner of two 15 C and a 15C LE that arriwed to me in Sweden from US today. Sorry to bother, but I tried the On/X (and On/+) self tests but I almost instantly got Error 9. Is this acceptable? On the other hand I saw the errata about the g/Enter + On tests and the tiny machine passed all three. What, if anything, am I missing?
Cheers, Re: HP 15C LE On/X ? - Luiz C. Vieira (Brazil) - 08-10-2012 Hi. You are correct, these former tests no longer work with the HP15CLE. I have one working perfectly fine and the behavior is the same. Congratulations on your new calculator! Cheers.

Re: HP 15C LE On/X ? - Matti Övermark - 08-10-2012 Thanks Luiz, Rest assured that I will spend quite a lot of time with the 15C LE now that it has the speed that I lacked. Indeed will I take down the Advanced functions handbook and see the speed-improvements - live. Oh, what a joy it is to be a nerd.

Re: HP 15C LE On/X ? - Luiz C. Vieira (Brazil) - 08-10-2012 Hi, Matti. That makes, ahn, "two" (not only...) of us all... I have two HP15C myself and one 15CLE, we match in these numbers. And I'm helplessly addicted... Enjoy!

Re: HP 15C LE On/X ? - Harald - 08-10-2012 Quote: No, that is not correct. The test works, but times out rather quickly. If you are fast, you can go through all the keys and pass the test. I have tested this on an original 15c and the test times out after a few minutes as well.
You can still call this a bug though, as the test should have been changed to suit the much faster 15C LE.
Re: HP 15C LE On/X ? - Luiz C. Vieira (Brazil) - 08-10-2012 Hi, Harald. Quote: Sorry, I did not get it. The ON/× (or the ON/+ and pressing a key) return all segments of the LCD lit when the calculator is OK, or [Error 9] when it is faulty. Shouldn't they return the 'all segments lit' then right after pressing the ON/× keys? Now it is my turn to ask if I am missing something. Or would you be referring to the ON/÷ test? Cheers.

Re: HP 15C LE On/X ? - Peter Murphy (Livermore) - 08-10-2012 Hej Matti,
With the calculator OFF, Press and hold 'g' and 'ENTER'; press 'ON' Release 'ON'; release 'g' and 'ENTER' The screen will display '1.L 2.C 3.H' Press 1 to perform the LCD test Press 2 to display the Copyright/Checksum message Press 3 to perform the keyboard test
Re: HP 15C LE On/X ? - Harald - 08-10-2012 Quote: Hi Luiz,
oh, sorry. Of course you are right. I was indeed referring to the ON/÷ test. Don't know why I though that was the one we were talking about.... Re: HP 15C LE On/X ? - Luiz C. Vieira (Brazil) - 08-10-2012 That's perfectly fine! We are all willing to help, even helping each other. The most important is: in the end, we're all getting to a consensus. Cheers!

Re: HP 15C LE On/X ? - Mike Morrow - 08-10-2012 Just make sure that you don't try to use PSE, nor should you expect any low battery warning before the 15C-LE quits and resets all memory after relatively short battery life. Also, if you do try the old 15C self-tests, usually program memory will be corrupted. These are three of the most serious 15C-LE bugs that apparently will never be fixed. I have two 15C and two 15C-LE units. I used one of the 15C units for 11 years. I have yet to recognize any real value to the 125 times speed-up of the the 15C-LE. Few attempt problems on the 15C that would only be considered, if only it were 125 times faster. :-)
I've gone back to using my 1985 HP-15C (rather than the 15C-LE novelty item) when I'm keeping my grossly more capable HP-42S units out of harm's way.
Re: HP 15C LE On/X ? - Matti Övermark - 08-11-2012 Hej Peter, Yes, there seems to be some changes in the self-tests for the 15C LE. Thank you (all!) for straightening things up. I did the complex calculation in the AFH/15C pages 086-089, and it took just 5 s to be compared to the 15C:s 9 min (540 s-ish). Isn´t things just fun when they're fun... ;-)
