It is very unlikely to be a similar case here.  It is a dedicated circuit for 
that end of the shop - no UPS - but no excessive loads either, and no A/C or 
anything to cause browns or surges.  It's a straightforward, lightly loaded 
line.  And in any event, nothing brown or surge related or indicative of it 
happens anywhere else in the shop, so I would tend to rule out that 
possibility.
If it is power supply related, I would think it to be something inside the 
adapter block maybe breaking down....perhaps a diode or a capacitor, but even 
that is petty farfetched if you ask me.

I guess I should swap power adapters since I have two.  It's just a pain in 
the arse crawling around down in back of those machines.....and it hadn't 
occurred to me until now anyway.  I just wish that problem were more frequent 
so I could test it and get results one way or the other.  As it is, that 
modem hasn't entered another failure mode since that first time a few days 
ago.  A feller could get awful rusty sitting around waiting for it to happen.
