hey guys, I've a HP premium 800VA UPS, and the PSU on my system would be 300W or less for sure. Whenever there's a power failure, the computer just restarts. Seems the UPS is not able to switch as fast or something of that sort, I've no idea why. For 1 second the PC switches off and starts of the UPS battery. However 1 thing to be noted is that, this happens only during a power failure. I've manually switched off the plug many times to test it, but all the time the UPS does its job and switches to battery without problems. Only during the actual power failure the PC restarts in 1 second. Also this happens most of the times, though not always Can anyone tell me why this occurs?
