Is the smell like that "Ozone" smell you often get from those ionizing air purifiers? That's kind of what I'm imagining it as.
it isn't ozone or electrical, smelt chemical... I guess. I hadn't smelled anything like it before. Its not rotten egg.
I hadn't needed a UPS before so this is my first. Up until now I have mostly used surge protectors. Just unplug from wall and sit out thunderstorms. It doesn't normally waste that much time in summer. We were meant to have storms last night, I left UPS on but I did unplug the network switch as I didn't connect its cable onto back of UPS yet, need to buy another cable first.
The number of times we normally have power outages can be counted on one finger per year... if that. The last time I recall us not having power for more than 24 hours was 23 years ago when it was shut down due to bush fires damaging lines. Its not normal. Most times its only a few hours at most, and normally we are told about it before it occurs. Unplanned outages are rare.
We don't get brown outs.
I did find results on Google saying the smell can be normal. But the smells mentioned were mostly electrical or burning plastic... maybe 2nd is what it is.
Its not so bad today but I left my window and door open all night so it didn't get a chance to build up. I was about to say I can't smell it at all now but it comes and goes. That and having the chest of drawers on far wall now opened room up and less places for smell to linger. The tall brown one would also trap hot air in summer so I don't mind it gone.
leaving next reorganisation of room until I get a new monitor, and I also need two extension cords with piggyback ability, as I need a flat plug to put into wall behind my bed, and most Australian power plugs look like this
and stick out from wall too far for me to be able to have bed close enough to wall behind, for pillows to not fall down the gap constantly. That has stopped me using two layouts for ages. Both outlets in my room suffer from the same problem. Placement.
Same thing happens in the spare bedroom. That factor also means I have to move the UPS as I can't run it off the cable as its wrong gauge wire. Also could mean PC needs to move as well. Really, only thing that doesn't move in that reorg is the brown chest of drawers. Its staying over there now.
