How to Buy and Use an Uninterruptible Power Supply(1)
Do you have a desktop PC and dread seeing the power go out? Got a wireless router and Modem that share an Internet connection that goes 'black' when the power goes out?Do you have one of those 'VOIP' phones that needs an internet connection to call in emergencies? Have you lost work and data, even hardware when the power went out?
You don't have to worry about it again!
Buy an uninterruptible power supply (UPS), and your computer will stay up during brown outs, and be able to weather black-outs, or at least shut down more gracefully when the power goes off and stays off.
Steps
1.Shop for a uninterruptible power supply.
a Look in office supply stores, big box electronic stores, specialty computer stores, or on the internet.
b For a desktop PC, you're looking for is enough power to supply your computer (the beige or black box), the monitor, and whatever critical IO devices are connected to it.
Most UPS packaging has a list of what the UPS 'should' back up, and for how long. 15 minutes should be plenty long enough to close your documents and shut down safely. An hour will let you 'finish' whatever it was you were doing, and possibly
A printer is not critical, and laser printers eat too much power to plug into a UPS.
Amplified speakers are not critical.
A MODEM or ROUTER that supplies the computer may be critical
c For a router/phone internet connection (presumably with a notebook), you only need a smaller UPS to keep it running for hours.
2.Get the UPS out of its box
3.Follow the directions for it.
a Plug the UPS in
b Plug the monitor, computer and any ABSOLUTELY CRITICAL devices that require power to keep the computer from crashing into the 'Battery protected' plugs
Most UPSs have surge protected plugs that don't offer battery back-up.
4.Even if you don't use a phone line MODEM, if you have a phone on the desk, use the phone filter. You could save yourself an electrocution in the event of a lightning strike.
5.Plug in the monitoring cable (usually USB nowadays) and install the software (or install the software and plug in the cable, as is sometimes called for in the instructions).
6.Configure the software to safely shut down or hibernate the computer if the power goes out and you're asleep or otherwise disposed.
7.After a few hours, the UPS battery will be fully charged and the system will stay up through short black-outs, or at least shut the system down normally when power is interrupted.
