UPS turns off PC, emits constant beep, seemingly random...

[Anonymous user]

Hi, I have an ES 350, and i have my PC and two monitors plugged into the battery backup part, as well as speakers and some other stuff on the surge protector portion. Seemingly randomly (doesnt happen too often, once or twice a week), the PC will shut off, the UPS will emit a constant beep, and the green light will turn off. I have to press the button on the UPS to get the green light to come back on, then I can turn my PC back on. It doesnt say anything about losing power in Powerchute (latest version off website). Any idea what is going on? I dont want my computer to turn off without being shut off properly, dont want to corrupt any files. Thanks for any help!

Hey thanks for the reply! I have my PC with 3.2ghz C2D, 8800, 4gb ram, 3hdds, 550 watt PSU as well as a 24" lcd and 20"lcd on the battery backup portion. It probably is an overload issue.

I would start with maybe a pull plug test on this to see what it does when you are watching it during a power outage. Disconnect the USB communication cable that goes from the UPS to the computer and all of your critical load plugged into the battery back up side.

You want to plug a non critical load on to the battery back up side (not the computer of course) - something you can tell if it turns off or on - maybe a clock radio or something like that. Then just pull the plug of the UPS from the wall (simulating an outage) and see if it supports the load. This would at least tell us if the UPS is doing its job during an outage. If it fails, we may possibly have a battery related issue that is not getting caught by powerchute if the UPS is turning off so fast.

If the test passes, then maybe we want to calculate the exact watt draw on your load as the UPS could be overloading. I dont think this model is able to tell you from powerchute what the watt draw is. This UPS can handle only 200 watts. A PC may pull ~100 watts on idle, if its a bit beefier and if its an LCD monitor, say 19", it can be ~50-90 watts at most.

Hope this helps!

Yes I agree. That sounds very high end so I tend to agree that is probably an overload or something relating to it.
