My dad has a APC UPS that started whining after a storm we had about a month ago, since then i've unplugged it from the wall and plugged his computer and monitor straight up into the wall considering we used the UPS as a multiple output power source. when it was still in a wall outlet it was continuously whining, after i had unplugged it from the wall, it was a short whine only when i pressed its power switch. so, i've unplugged the computer and anything that could be damaged if there are any surges prior to its apparent lack of component protection. I took some time off from thinking about it, and googled the problem and at one point read something about a circuit breaker or a fuse. i looked at it today and the only fuse i found was a 60A that hadn't been broken, and im not one to just go poking around at different capacitors and breakers.

so, my question is if anyone has had a problem with a UPS particularly one as the same model or the like of my dads. I'm also trying to fix it without buying another for over $200, so anything that would help with the diagnosis and repair would be great.

Software A lot.
Benchmark Scores Its fast. Enough.
No oozing caps or burned traces? Probably fine. I have a Belkin here that buzzes occasionally when it performs a self test or when it decides to charge the batteries.

well the thing about it is, it doesn't work. it didn't work after the storm while it was whining, and today i didn't see any noticeable damage when i was looking at the circuitry. Though, also it didnt do anything when i tried plugging it back up to try and diagnose it, no power, no whining, no nothing. i put my ear closer to it and tried to hear something i heard a really faint buzzing sound coming from a component, and i couldnt recognize what it was.
