I have some automated pet stuff in my house. There were 2 power outages 2 days in a row. After each one, the pet electronics refused to turn back on even if I unpluged and replugged the power brick from the wall outlet side. They would only turn on if I unplugged the power brick on the electronics side and plugged it back in.

This is kind of a pain because of the cat stuff we own is a litter robot and where it’s placed is really tight. It’s a huge hassle to access the back side of it to unplug the power brick.

So my question is, why does this happen and are there any workarounds so I don’t need to unplug the power brick when it happens?
