I thought I'd come here and ask for some technical help; I got an uninterrupted power supply a few years ago and just now I saw some sparks inside the machine and can smell an odd burnt/burning smell (I saw the sparks because the machine has its back to me).
It's not showing any kind of special problems (its face has a few lights that can shine up if one of several problems are at play). I'm gonna switch it off and restart it just in case, but thought I'd come here and ask for any tips. I'd rather not try and get a new one as these are heavy and a hassle to move from a new shop to my car, and then to my room.
It's only got a load of 15% at its highest, and it's usually fully powered at 100%.
i see. maybe i dont know how much power a treadmill uses, but usually a home UPS is just to keep the PC on for a bit for you can shut down. My UPS would let me run a PC with monitors for about 38 mins. Mine is 1500VA.
