Opening a HP41 Message #1 Posted by Roberto FURLAN on 24 Dec 2005, 10:23 a.m. Hello Everybody! After a little battery leakage with corrosion on one of the contacts, my 41 doesn't turn on anymore. Anybody knows how I can open the case to look inside? Thank you very much and Merry Christmas!

Pay attention when you will colse the calc; check CPU plastic connectors for allignment and don't FORCE SCREWS to much because you will break plastic post retaining them. Good luck!

You could first try cleaning the contacts and springs again with vinnegar on a Q tip. Sometimes you have to wiggle the battery in place (it moves just a little bit). If the metal on the contact is corroded through; you can get metal contact paint, either in a pen (Katie uses this) or a bottle of "Nickel Print" that you brush on. If you want permanence and beauty; Diego Diaz should soon have the replacement flex connectors that he is having made.
