BK500EI (UPS CS 500EI) Orange LED flashing

[Anonymous user]

Whenever I connect this UPS into  electricity  nothing happens only  orange LED (On Battery) is flashing really fast. Power button doesnt work.

Exactly same thing happens even if I remove battery from unit.

Is there anything I can do with it?

Thanks

There is no audible tone with this, correct? I don't see this listed as an indicator. It is definitely the on battery amber/orange LED and is not one of the red ones? So, if there was not a mistake on which LED, I am not sure what it means but its probably not good. If you remove the battery, you can hold down the power button to try and discharge the UPS completely to reset it. If no change, I'd say you could pursue a trade in and/or replacement if you need it.

Its indeed orange light - "on battery"  and is flashing really fast - you need to disconnect it from power source to make it stop flashing, nothing else helps.

The unit is out of warranty so I guess there is nothing to do about it

I was hoping for some advanced reset trick.

Nope, these are simple units so beyond removing the battery as well as removing the UPS from AC power, holding down the reset button for 15 seconds and restoring the battery and AC power is the only thing to try.
