I have a UPS Smart-UPS 1400 XL with three add on battery packs. A week ago I shut down the unit because I was going on vacation (yes, first mistake). After turning the unit off, I noticed that its internal fan continued to spin for sometime. In a moment of brain freeze I unplugged the unit. All was fine until I returned today and tried to start it up. I plugged the unit in and had a constant alarm with all the warning lights lit. I tried pressing the reset and off buttons, to no avail. Eventually I unplugged it again. Now when I plug it in the alarm sounds for 5 seconds, then turns off. The battery indicator on the right has one led on. I wait a few minutes and try to turn it on and the alarm sounds.
Can anyone tell me how to fix this? I promise to never shut the unit off again! Please let me know if you have any questions. I am borrowing a neighbor's laptop since with no power my server, internet and everything else is dark in my office.
