Electrical Problems - all units turning off
Posted on 2011-02-28
We've got a strange situation. Have a client who previously had a couple of computers and a dsl modem connected to an APC backups 1100va battery. The battery seems to work ok. There were a couple occasions where everything would suddently turn off though, even without a power outage.
It wasn't worth fighting or diagnosing. They started using a APC SmartUPS 1500, that was used but with relatively new batteries. The strenth indicators show at about 90%. The crazy thing is that the problem is back!
Can anyone think of something that would cause a battery and all downline equipment to just turn off? Even if the outlet is bad, shouldn't the battery keep the equipment on for a bit? We've tried pulling the plug from the wall and the equipment does stay on.
