Most consumer UPS's don't have anywhere near the power protection that a good surge suppressor power strip has. I know of a case where a customer was having similar trouble. A power line analyzer (expensive piece of equipment) was plugged into the power line and showed problems whenever the building elevator started moving. It turned out that the elevator and the power outlet shared a power feed.
Interesting. I decided to bring their UPS to my lab with their computer and check it for a whole week. If it works ok, then I know they have a problem with the electricity in their home.Quote:
