I thought a Belkin owner would tell me to push some button twice and hold it for a few seconds while I stand on my head and that would turn on the UPS feature. ;) > Dunno.

If the bad cell turns out not to be "definitive," then this is my next guess. I just remembered that my external drive cases each have four hard drives. That makes eight external hard drives. Add that on top of my dual G5, powered speakers, 20" display, and iBook. That's starting to sound like a lot although I think I had the problem back before I added the drives, speakers, and iBook. It didn't occur to me that there could be an effective wattage limit in addition to the volt-amp limit (720).
