Once in a while, after leaving my Amiga unattended for 12 hours or so, I get to it and it is crashed. No video, and no warm resetting! Nothing.
I have not been able to figure this out until just now, maybe..
I have my A3000UX plugged into several UPSs. All APC's, all different. They all do what they're supposed to. The one the motherboard power supply is plugged into just made a weird blee-EEeeep and cut the power to my Amiga for I'd say about 50ms! And, the A3000 went into the state stated above.
Obviously, this is really really bad.
Has anyone else had such a problem with a UPS?
