HP-41CX Frozen Up Message #1 Posted by Jeff Davis on 24 June 2009, 9:57 p.m. I have a frozen HP-41CX. Does anyone have any ideas? I have tried the MEMORY LOST reset and no go. Please let me know if you know any other tricks.

Re: HP-41CX Frozen Up Message #2 Posted by John Robinson on 24 June 2009, 11:38 p.m., in response to message #1 by Jeff Davis Try shorting the battery terminals for a while, the outter two that is. Just connect them together for a while, i.e. minutes, if not hours and try again. This assumes the calc was working at some stage recently ? Cheers, John

Re: Ask and ye shall receive: [HP-41CX Frozen Up] Message #4 Posted by Jeff Davis on 25 June 2009, 6:46 p.m., in response to message #3 by Karl Schneider Well, Shorting the terminals did not work either. It was working just the other night when I started having problems with my MLDL2000. I was trying to program the HEPAX and all of a sudden it stopped working. Help!

I remembered once that someone told me to reverse the battery polarity and press and hold the on button for ten seconds. The old babe sparked back to life with "MEMORY LOST" Thanks for all the comments.
