HP-41c Enter Button Message #1 Posted by Timothy Rudd on 16 Oct 2006, 7:02 p.m. Hi I recently acquired an HP-41c from a user on this forum. The unit is amazing asside from one thing. The Enter Button on my 41c works fine the only thing that bugs me is that it has a loose feeling. The button seems to only be connected on the left side and the right side of the button sinks lower, unless you turn it upside down then it falls to the normal location, only to fall back down upon righting it. Is there anything that I can do to fix this or is it something I should just live with. If someone would like to see what I'm talking about I will try to put a pic up for you. I would appreciate any help. Timothy

If the key still works, I wouldn't recommend trying to fix it. To take the keyboard apart you have to drill out heat stakes; it wasn't designed to be repaired.

Re: HP-41c Enter Button Message #3 Posted by Klaus on 17 Oct 2006, 3:25 a.m., in response to message #1 by Timothy Rudd I once had a old HP-41C (version with high keys and the charger contacts), and it had the same behaviour. I don't know if this is really a defect, or if HP did support the Enter-key with only one contact [in the first version]. I think the HP-45 also had only one supporting "contact spring". **Edit: Added the text in brackets Edited: 17 Oct 2006, 5:11 a.m.
