First time APC BACK-UPS user needs help with the Building ..

The UPS is also a surge suppressor. It will use the 3rd wire ground to route
any surges through. You probably don't have sufficient ground on the screw.
Another thing that can cause the light to be on is high neutral voltage, a
common problem in old buildings. The UPS part ought to work, the problem is
going to be with the surge suppression. Also, there may be some other
problem in the building wiring that could cause a problem for the entire
building, depending on what it actually is.

I rent in this apt complex
So rewiring might be out of the question. Maybe there is a way to run
a ground wire but from where to where?
The breaker box is just 2 feet from where the UPS is pluged in. A
coworker said if I can find a water pipe I can run a wire from the
water pipe to the outlet where the UPS is pluged in. Is this true?
What am I looking for with this outlet tester?
TIA

It's possible the plug is not polarized correctly
unplug it and flip it around. It the red light is still on then put it back
the way it was as evidently there is a grounding propblem<!-- ~MESSAGE_AFTER~ -->

If it's an old building with old wiring, it's possible that the outlet box is
not grounded at all; if so, the wire you attached to the plate screw is not
connected to ground.<!-- ~MESSAGE_AFTER~ -->

Is there a way to fix this if it is the problem?
I just want make sure my APC BACK-UPS will be able to carry out in the
event of a black out or brownout. I get frustrated when I lose work
when brownouts happen (though minnor).
TIA!

Yes! the outlet needs to be properly polarized and grounded.

If you use the UPS as it is presently...you may still have brownout
protection...
but there is definately a safety issue.

Although you landlord *should* pay to have an electrician repair it...
for the purpose of safety...maybe you could offer to pay half. It's a
relatively
minor job.<!-- ~MESSAGE_AFTER~ -->

Safety ground is unrelated to battery backup - from
blackouts and brownouts. Most common failure of a UPS is dead
battery. These plug-in UPSes tend to lose batteries in but a
few years - rapid battery failure. Test is quite simple. Use
computer with battery backup unplugged from wall receptacle.
If computer works for many minutes, then battery inside
battery backup is OK.

That ground light does nothing for transient protection. In
fact, that APC UPS does not even claim to protect from
destructive transients. Read their specs (if even
available). It claims no common mode transient protection;
which is irrelevant to that red warning light.

That red 'missing ground' light is reporting a human safety
problem and a possible threat to interconnected electronics.
Your receptacles are only two prong because no safety ground
wire exists. Using the receptacle screw will do nothing
because that safety ground wire is not installed. Only
solution is to run a safety ground wire from breaker box.
Even grounding to a cold water pipe is a bad and completely
unacceptable solution; may create a threat to human safety;
and not even sufficient as an earth ground.

Note the difference - safety and earth grounds. That wall
receptacle is missing a safety ground which is different from
earth ground. Earth ground is necessary for transient
protection. That red light can not report and does not even
claim to test the existence of earth ground. That red light
reports a human safety and other potential problems.

Speaking of UPSs, I have here a non-functional APC 420 Backup Pro
that I picked up for $5 at a tag sale. I suspect it needs only a
battery. Can I try it out with something like a car battery
hooked in to check, and if it flies where does one go for a new
internal battery?

Meanwhile an APC BE350, which came from a Staples close-out at
about $30, is doing fine. I also have old wiring with 2 pin
plugs, so the power fault is always on. It gives me about 5 to 10
minutes to shut down.
