    Sometimes when the air conditioner in my window kicks on, my PC goes to sleep.

    Why? The PC is using a UPS. (APC Back-UPS 600) Shouldn't it prevent this? PowerChute says it has switched over to battery a few times due to electrical noise. I'm assuming that's when the AC kicked on and the PC went to sleep. How can I prevent this? I can't plug one into a different circuit because the whole room is on the same circuit. I'm using Windows 10 Pro, is there maybe a power setting causing the system to go to sleep when switching to battery?

    Thanks!

    Go to Control Panel > Power Options. Click on your selected power plan. Then click on 'Change advanced power settings' . In the windows that then opens, find Battery at the bottom.

    Most of the settings there deal with low or critical battery level. So maybe your battery needs a replacement if it is automatically going to hibernation when power is unplugged.

    There are no battery settings under advanced options. I believe PowerChute is handling battery settings.

    I haven't tried removing the UPS, but I don't remember this happening before installing the UPS.
    I've turned the electrical noise sensitivity down a little on the UPS. The AC has kicked on twice now without affecting my PC, so hopefully this has solved the issue.
