|Help Needed - My strange HP 41CX|
Message #1 Posted by jbssm on 23 May 2006, 5:47 p.m.
I have a HP 41CX fullnut (I already wrote because of this some time ago).
It's behaving very weirdly, so I'll enumerate what happens:
1 - It doesn't turn ON, by pressing ON
2 - Sometimes I can turn it ON by pressing BACKSPACE+ON (suggestion from a forum member)
3 - It always turns on by pressing BACKSPACE+ENTER+ON
4 - It retains memory after being turned ON and OFF, either in stack or in STO / RCL Command
5 - Everything seems to work fine, inclusive the Catalogue
6 - The exception is that when I press PRGM, or SST keys, it simply freezes
Now, I can't understand, I would expect that all simply worked or not, but this strange behaviour is giving me headaches.
Any suggestion on how to solve it?
Also, now I'm curious, what can be causing this?
Regards to all and thank you for this wonderful mailing list.
