Disabling that annoying UPS beeper

UPSs, or uninterruptible power supplies, are great for preventing your computer from crashing in the event of a power outage.  They at least give you enough time to save your work and shutdown the computer safely, and some even allow you to go on computing for 30 minutes or more.  The problem with most UPSs, though, is that they beep, scream when the power goes out, as if the computer equipment is sucking the life from it.  I swear, the sound of ultimate suffering goes "BEEEEEEEEEP!"

…I think that beeper is annoying.

Luckily, it’s relatively easy to take that sucker out!  Here I’ll show the steps I took to remove the beeper in my Dynex DX-800U.

First, I unplugged everything from the unit, turned it off, and flipped it over.

Poor guy.  I told him that it would only hurt for a little bit.

Next I removed the screw that kept the battery cover closed, and then removed the cover.

The next thing I did was find a screw driver that was long and thin enough to fit in those long, narrow screw holes.  Once I did that I removed the remaining five screws and pulled off the bottom half of the case.

Ah, there’s the culprit!

I was going to wait until the next day and get a soldering iron to melt the two contacts on the other side of the board so that I could just slide the beeper right out…

…and that probably would have worked, but I got impatient.  Instead I decided to just attack the beeper and render it mute.

Putting the cover back on was a bit tricky, but after I worked out how the power cables to the battery folded it went smoothly enough.  To test my handwork I plugged a light into the UPS and unplugged then unplugged a light from the wall and… silence.  Happy day!
