Here's what I'd try:
1. 1st, cold boot the system and check the limits are not at the wrong settings, aka something hasn't changed your Gemini limits or settings and your system thinks it's at one of the end limits. This stops RA drive! But also usually gives a buzzer.
2. Connect your Gemini via Gemini ASCOM (via RS232) then switch the Gemini on, cold boot and run it via the Gemini ASCOM, use the virtual handset to command drive and slew the system not the actual handset. (you do not need to have the motors in the mount to do this,
Also use Gemini ASCOM to look at the Gemini Advanced settings to see if something isn't set right!
Anyway if it works with Gemini ASCOM then well I'm not sure .... but I reckon it sounds like a hardware issue with RA drive.
But before we jump to conclusions do get back on cold-reboot and Gemini ASCOM tests.
I just re-read.....You said the alarm did go off...hmmm sounds like the Gemini lost it's positional way and thought it was at it's limits...cold boot (Counterweight down) and check the Limits, use Gemini ASACOM to do this.

I keep thinking this has to do with the battery in the controller going bad. It is about 2+years old.

Batteries at best last 2 years (with the CR2345) the CR2032...much less.
A battery issue could corrupt SRAM data, this has no effect when system booted and running on internal power, although a bad battery may have corrupted the data already.

Last couple of times I brought it out I was causually observing and just used "warm start." And kept using that to restart the mount. All I had to do was properly follow directions and "cold start." Course it was the mount limits all along. Time to order a new battery also.
