Great! You've not reset it yet. Message #6 Posted by Steve on 25 Aug 2000, 12:26 p.m., in response to message #5 by Steve Dimond
In the book Exteny your HP41, section 4.1, a number of methods are given to revive a calculator that won't turn on.
OK, yours turns on, but it's unresponsive.
1) press backarrow and/or shift to see if the blank display is caused by alpha blanks in the X register
2) press on then backarrow, then on, then backarrow a few times, pausing about 10 seconds between keystrokes
3) remove all modules and try again (there's also mention of the use of an AM radio here too, as well as chacking for dirty battery terminals, flat batteries, and incorrectly inserted batteries)
4) IF YOU HAVE A NEWER HP41, try pressing backarrow and enter then on, then releasing all three
5) if you have a wand try reading some barcode
6) try pressing R/S
7) attatch a card reader and run a card through it
8) take out battery and reinsert. then press ON a few times
9) obscure
10) memory lost (aaagh!)
11) take out batteries for a LONG time OR insert batteries the wrong way (using old batteries) (POOR ADVICE IN MY BOOKS) OR short the battery terminals (place wire or foil over the gold connectors. It's the outsoide two that you need to short, but you can connect all of them without any problems)
12) really nasty
13) even worse
I used to have a card with an autoexecute program on it. The program was simply STO c. That worked for me once too. It is actually mentioned in step 10 in this book too.
Good luck.
