Chosen Solution
My ups, after 5 years of continuous operation shows the overload’s light . I unplugged the PC and I replaced the battery but I have not solved the problem. Then I opened it to see if there are components that are burned or leak but nothing. To be sure I replaced the cooling fan but nothing has changed. Can anyone give me some tips? Thank you very much.
Thanks to all. I have not solved the problem. I replaced the old ups with a new one.
Roberto, If it alarms, even with nothing plugged in, then it is possible that one of the MOSFET on your mainboard has failed.
Hi, i had the same problem twice…!!! My battery was ok, everything was ok but the beep keep going on, for overload… Both times i fixed doing these steps…
- Turn off the unit
- Flip over the unit
- Open the battery-cap and turn the power on
- Green Light is flashing
- Try Now (with the green light flashing) to disconnect the battery…
- Now it should be ON with the Empty battery light on (Red light)
- Connect again the battery as it is… Now it should be ok…!!! Good Luck…
