Dead HP-31E, where do I start? - Paul Gaster - 01-17-2011 I have a HP-31E that is dead and I am not sure where to start. Re: Dead HP-31E, where do I start? - db (martinez, ca.) - 01-17-2011 first, do not plug it into that charger. never. if it is dead; that is probably what killed it. Edited: 17 Jan 2011, 5:19 p.m.
Re: Dead HP-31E, where do I start? - Paul Gaster - 01-17-2011 Thank you, that did the trick and I now have a calculator that comes on and seems to work in general, but it has a new problem.
Re: Dead HP-31E, where do I start? - Norman Dziedzic - 01-17-2011 I second that request :-)
I have a 31E with some missing segments. The lower left segments are out for all digits on my 31E.
Re: Dead HP-31E, where do I start? - db (martinez, ca.) - 01-17-2011 it might be the pressed-on chip problem. maybe. Re: Dead HP-31E, where do I start? - Norman Dziedzic - 01-18-2011 Thanks db. My S/N is 1849A24700 Made in USA
Re: Dead HP-31E, where do I start? - Walter B - 01-18-2011 We had this topic recently: IIRC, you can't differentiate soldered/solderless by s/n but you can easily by weight. Please search the forum. HTH
Re: Dead HP-31E, where do I start? - Mike T. - 01-18-2011 You lucky man - I swapped my HP31E for an HP32E (and quite a lot of cash) way back in 198x. Don't regret it but the HP31E is now definatly a collector's item...

Re: Dead HP-31E, where do I start? - Norman Dziedzic - 01-18-2011 I don't have a battery door and I'm at 171g weight. I think this means solderless and not good for me :-(
Re: Dead HP-31E, where do I start? - robert rozee - 01-18-2011 i have two 31E's here, which i had planned to 'retro fit' with larger modern LED displays. should i be holding off on this plan?
both seem to have small bubbles in the plastic lenses over the LEDs, along with some frosting. and both are well-worn, though at least one functions ok.

Re: Karl's method for opening the Spice series - Paul Gaster - 01-18-2011 That looks good. I also found a link with some pictures and a different method for separating the case. Not sure who made this page, but it may be helpful. Re: Karl's method for opening the Spice series - db (martinez, ca.) - 01-18-2011 I've used that method. It works fine too. I just wished i had longer fingernails and more fingers. I don't know who made that page either. Nicely done though.
