Overload alarm lights and sound
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.
Ist dies eine gute Frage?
