Hi,
Is it normal for the computer to restart when you run a self-test in Power Chute? I have Power Chute Personal Edition 2.1.1. running under Windows 7 SP1. I just tried running the test and my system rebooted itself after a few seconds. I've been having some problems with my computer so I thought the reboot might be a sysmptom of something else and tried the test again and the same thing happened at about the same point. I don't see anything about this on the help screen in the software.
Thanks for your help.
Tarani

Thanks for your reply. I tried unplugging the UPS with my newer PC (the one with the problem from yesterday) plugged into it and it did turn off. I then did the same thing with my old PC and it stayed on. The reason I bought this UPS a couple weeks ago was that my new PC was rebooting itself spontaneously. It was on an older APC UPS. Dell replaced the power supply and motherboard last week as a solution.There are differences between the 2 PCs. The new one runs Windows 7 with PowerChute 2.1.1. The old one has XP with PowerChute 2.0.

Our UPS performs a self-test every 14 days or 2 weeks, have you ever noticed your PC doing the same thing during this automatic self-test? Also, have you tried unplugging the UPS and letting it run on battery? Does it reboot/restart the PC?

This would help us know if the sinewave or transfer time affects the load attached to it.

I just did the same steps as before, unplugging both PCs from the UPS but this time I used my old UPS and both PCs stayed on. Any ideas what's going on?

Sorry, I meant to say that I did the same steps using my old UPS and both PC's stayed on when I unplugged the UPS. Hope this is clear.

Is it possible for you to provide the model numbers of both UPS's. I have a feeling that your new PC doesn't like either the transfer time or the output wave form of the new UPS.

If you are using an APC Back-UPS, below is an APC Knowledgebase that I hope could help you out:

The model number of the new UPS is ES 750. The old UPS is ES 550. I checked the load on the battery backup and it is still quite low. The equipment on it is 1 PC, 1 printer, 1 ext. hard drive, 2 monitors and a router.

Both unit belongs to the same UPS family which is Back-UPS ES. Both would almost have the same topology and design. Can you send me a PM of the model and serial number of these 2 units. This can be found on a small barcoded sticker located underneath the UPS.

Here are the numbers for both units:
New unit with new PC plugged in: BE750G and 5B1050T50019
Old unit with old PC plugged in: BE550G and 3B0811X60086

Hope this helps.

Hi,
Do you have any further insights into this problem? For now I have the new PC plugged into the old UPS, which is already a few years old and may not last much longer. If I can't use the new UPS I'll need to return it. Or would it be covered by the warranty?
Thanks in advance for your help.

Since you have a BE750G, I would like to check more on your end.

This particular UPS has a master control feature, can you check if the master enabled LED is lit up. Can you also tell me what are those devices that are on the Master Outlet, Battery Outlets, Controlled by Master Outlets and Surge Only outlets. Keep in mind that Controlled by Master Outlets are surge outlets as well which means that if you turn off the UPS or loose power, these outlets would turn off as well. If the master enable function is enabled, once the master is off or it detected that there is no device drawing power from it, it will tell the controlled by master outlets to turn off.

The Master Enable light is on. I have (had) the PC plugged into the Master outlet. In the battery outlets are an external hard drive, two monitors and the Internet cable. The only thing plugged into the Controlled by Master outlet is a printer, which I moved to one of the Surge only outlets while the PC is plugged into the old UPS. I also have a router plugged into the Surge only outlets. This is all working fine. The printer goes off when the PC is turned off.

How is this related to my problem, as described above, i.e. that the PC turns off when the UPS is unplugged from the electrical outlet? If there's some incompatibility between this PC and the UPS, then the unit is not very useful to me. What are your thoughts on this issue?

I just wanted to be sure that it is not the Master Control feature that is doing this. Can you send your account details (Full Name, Address, Contact Phone, E-mail, Company Name if this is being used in business) thru PM?
