Question my backup ups goes on battery mode even if the line is on

[themadlieut]

after a while it turns back to normal but like right now it went on until i think the autonomy was over causing the pc to shut down, i wasn't even doing anything demanding as i was just on youtube, the current model i own is the same i had for over 2 years that fried after some terrible weather, i had no issues like this with that one, i also did not upgrade anything in my pc nor added new peripherals that could cause an overload, the current ups is actually a replacement of a new one because i though it was defective, but since both are showing the same issues it might be something else...but what?


i'm not sure if this is the proper section, if it isn't please let me know

Is the input voltage steady?

My UPS will switch to battery if it detects an input voltage over 136v and below 88v.

i currently don't have a tester so i have no idea, i'll try to get one asap, since the whole thing begun after the storm, could it be the power strip or the electtric plug gone bad? externally they seem fine, i can't even check the plug because it's behind the wardrobe and it's hard to reach
