Wow. I've had this unit a little under 2 years, and came on here (and other sites) to see if anyone else had this problem. They do, in spades. The thing just shuts down totally, seemingly at random. Other times it trips and beeps incessantly like the power is out, yet the table lamp plugged into the same duplex outlet is still on. Other times it trips for a second, comes back, trips again... repeat.Never had this issue with my APC. Which incidentally is NOW on the same branch circuit and doesn't trip while the Tripp Lite still does. I always liked Tripp-Lite surge protectors but this UPS is a pain in the ___ .
