Your circuit may be overloaded. Try plugging in the Partner in another circuit in another room using an extension. Also suggest you put a meter in the same outlet as the Partner and see if there are any voltage dips when these large appliances come on.
Also, just because you have a UPC doesn't mean it's stil working. Batteries do get weak and go bad. Easiest way to test a UPC: unplug it. Does the attached equipment stay up? The meter is also useful here.
Also, the laser printer, fax, microwave and refrigerator should never be on the same circuit as the Partner or any electronic equipment. These all have a very large current draw, especially as they start, and at the same time they put out a burst of static.
