I have one question about this 24/7 situation. I would love to just leave
my pc on all the time. In our area, Charlotte, NC, this is thunderstorm
season. Now, I have my computer and modem line running through a UPS. If I
leave my pc on all the time with a UPS, and the UPS gets hit by lightning,
has anyone ever had the experience of their machine still getting fried,
or is a UPS a virtual guarantee that it will be safe. If anyone has had a
computer on a UPS fried, I know there is a guarantee up to $25,000 or
something from APC at least, but has anyone ever tried to collect any
money and have they been successful or unsuccessful. Is it easy or hard to
prove lightning storm damage? Interested in what others think.
