I appreciate the suggestions. Let me add some additional detail that might help me get more helpful suggestions. The display on the unit is completely blank (black) with nothing showing. I've tried unplugging everything from all outlets and pressing the on/off button and holding it for more than 1 sec. and no matter what I've tried the display won't show anything so there aren't any red lights, or visual clues what's going on. I only know that items plugged into the non-battery backed-up outlets work and items plugged into the batter backed-up outlets don't.The owner's manual says it's not user serviceable and I've been able to find the compatible battery online, but I'm not inclined to spend the time/money until I feel more confident it will solve the problem.Any thoughts on how to diagnose and then resolve the problem?Thanks,Randy

there are no user replaceable parts, dispose of it, why do you want one, computers do not need one, lose power when power returns restart and you are back where you left off.

Windows XP has gone long ago obsolete. Suggest upgrade with a new computer to Windows 10.

Windows XP isn't recognizing the new device because it is probably using USB 3.0 protocol.

Replace the battery.

Howdy howdy...MeisterApple, Took me a while to find your ENTRY again (sorry... My fault: a mere few minutes after you asked)... I had constructed an answer for you... replete with SPARE parts... and anti-static (ESD) protective cautions. (ALSO Strong caution against using CHEESY volt meters on sophisticated integrated semiconductor technology). My first suggestion was about those CRACKED batteries... Get those New/Good batteries away from your UPS before it ruins another set (of batteries). I have been UNABLE to find any decent MANUALS or TECH SPECS. Try to contact them in ...

(((Do not expect much help... just delightful banter))). The actual circuitry of a voltage monitor, alarm and battery operated inverter is (in principle) fairly simple... The NEW prices ARE pretty impressive... but good UNITS are available.. and you can repair or STORE your old one for PARTS... As you see fit. Just ONE major caution... As you handle these NEAR INDUSTRIAL grade pieces of equipment... You should seriously consider begging, borrowing or buying YOUR OWN anti-static WRIST Bands. Electro Static Discharge (ESD): a small spark (you might not even feel) can utterly destroy any nearby semiconductor it touches...
