WP-34S Resetting After SetDate - drdbthompson - 04-07-2019 04:47 PM
I pulled out my WP-34S this morning and noticed it would not power up. I replaced the batteries, started the calculator, and was greeted with "Restored."
At that point, I attempted to set the date. The calculator responded with "Reset" and would not accept a new date. Nor will it accept a new time.
After searching the forum, I cannot find a solution. Has anyone else experienced this problem? Is there a troubleshooting approach I should use to determine what has happened and how to fix it?
Thanks for any and all help.

It sounds like the new batteries are a bit flat.

Thanks for the note, Paul.
The problem seems to be resolved. The battery voltage is reported to be 3.3v.
I finally found the protocol to update the firmware (RTFM, of course) and renewed the firmware, just in case. The machine has been working fine all afternoon.
I have no idea what happened. It could be that I pulled the new batteries from the refrigerator and they were too cold to be at nominal voltage.
Again, thanks.
