WP-34S Resetting After SetDate

[drdbthompson]

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.
