DECstation 5000/200 battery backed NVRAM failure?

Just wondering if anyone knows if this could be a possible problem with this type of machine.

I have two DECstation 5000/200 systems. When I got them, one powered on but did not do
anything (no output on serial console on port 3), while one would work fine (console output
on port 3, seemed to be functional, etc). I did not have any external SCSI storage for them
at the time, so I decided to store them until I could make use of them.

About a week ago, I finally got a SCSI drive enclosure to mount a disk in, so I decided to try
getting one of the systems up and running with NetBSD/pmax. To my surprise, however, now
both of them do nothing on power-on! I had not touched them since I had power-on tested them
a few months previous, so I was at a loss as to knowing what had happened.

The only thing that I found that I even remotely suspect could be at fault is what looked like one
of those Dallas battery-backed clock/NVRAM chips. I was wondering if perhaps the battery had
died and this was preventing the system from coming up.

I was hoping someone else might have run into a similar problem and might have a few pearls of
wisdom to share.

Thanks,
