Hi Amandeep,

Is the unit beeping and if so what does it sound like? Are the LEDs flashing at the same time or are they alternating? Are you using the software and if so what does it report? Is this a model BE500-IN (found on the little white sticker on the bottom of the UPS)?

This doesn't sound like a normal fault but with the info above we can take another look.
