If your UPS is 2 years old or more: CHANGE THE BATTERIES!!

Most computer UPS units use sealed lead-acid batteries for 
back-up power. Most UPS units are run with the power on, 
charging the internal batteries, 24 hours a day, 365 days 
per year. After a couple of years you will find their 
capacity has been SEVERELY diminished due to overcharging, 
so when the power goes out, so does the UPS. You should 
also test that the UPS can power your equipment for at 
least 10 minutes on a regular basis (monthly). People tend 
to forget that there are batteries inside these units, 
until they no longer work.
