Hard drive keeps shuting off

follow this steps and fix it. God bless you
Plug the battery backup into a working electrical outlet. If the battery backup turns on when the power button is pressed, then the problem may be that the previous electrical outlet is faulty. Proceed to step three. If the battery backup doesn't turn on, proceed to step two.

2 Reset the circuit breaker on the battery backup. APC battery backups have a labeled circuit breaker button located on the unit near the phone line, fax line, USB, network and coaxial cable inputs. Press the button to reset the circuit breaker. Power on the battery backup by pressing the power button. If the battery backup powers on, proceed to step three. If the battery backup doesn't turn on, proceed to step six.

3 Determine if the battery backup is charged and providing battery power. With the battery backup on and plugged into a working electrical outlet, plug a computer monitor into one of the battery backup outlets labeled "battery backup plus surge protection" on the battery backup. (APC power supplies have some outlets that provide only surge protection while the other outlets provide surge protection plus battery backup.) Turn the monitor on. Unplug the battery backup power cord from the wall outlet. If the monitor remains on, the battery is holding a charge, supplying electrical power and the battery backup is working properly. If the monitor goes off, proceed to step four.

4 Charge the battery. Plug the battery backup into an electrical outlet and allow the battery to charge for 16 hours. This will fully charge the battery.

5 Test battery charge. Once the battery is fully charged, repeat step three. If the monitor stays on when power is interrupted to the battery backup, the issue is solved and the problem resulted from an incompletely charged battery. If the monitor turns off when power is interrupted, the battery within the battery backup is faulty and needs to be replaced.

6 Replace the battery backup unit. The unit itself is faulty. If the battery backup is under warranty, contact APC to request a replacement.

It sounds like your unit is not happy. When these things fail, they alarm and they must do so, or they don't get fixed, and then you're unprotected...

What fails usually is the battery, they just have a short life...So, they can be repaired, but most people replace, due to low cost to replace.

It is possible that the battery is okay, in which case, the issue is in the electrics. Again, fixable, but hard to have a tech open the unit and put in any part, and not be 3/4 the cost of a new unit.

If your unit is expensive, start testing, or send unit in. .....So, now what for your system? Again, replacement just works. You put the system down, replace the unit, power back on, and continue your life.

If the device was still under warranty, you should call APC support and ask to send it in for repairs or replacement. Just keep politely asking, and ask to talk to their superior whenever they say it isn't possible and eventually you will get an RMA ticket/number.
If the device is not under warranty, you might be able to convince APC to service the device for a fee.

How old is the unit? They only last so long before the battery can charge no more.

Disconnect the battery(s) from inside. The backup batteries are still working...

Batteries in the UPS typically last 3 to 5 years and it depends upon several factors. including the number of times the unit must go on battery power and environmental conditions. There are usually several batteries in the UPS and while the battery voltage may show 13 volts, this may only be a float charge/voltage and a true indication of the battery voltage and condition requires the batteries to be tested under a load. There maybe one battery in a set of batteries that is faulty and causes the whole battery system to fail and indicate a battery fault.

These lower powered and cheaper KVA type UPS are switch over types, when the mains supply fail, the UPS switches over to the inverter in milli-seconds which then supplies mains power but the power waveform is a pseudo sine wave (ie not a true sinewave. A faulty inverter circuit won’t deliver power when the mains supply fails.

most commonly this is called a bios loop, this is due to the fact of a currupted bios command or a damaged cpu. to eliminate bios you must disconnect battery and cmos battery usually located where memory is, cmos battery is a small cable attached to a metal disk. unattach hard drive and restart computer. after restart shut down computer and reattach battery. again start computer without hard drive. if bios screen does not appear and same sceneario occurs then your CPU is fried. If bios screen does appear and you reinstall hard drive and get same boot error then your boot sector of hard drive is gone.

Due to black screen at boot and boot loop I would say ypur cpu is gone.

You have a loose ground on the outlet. check it out................

One other thing, you have bought the worst, cheapest design and the least protective product in the world without AVR technology.
I am a power quality engineer and I loath APC quality.

check out some real UPS that might do better.

I would recommend replacing APC UPSs with ONEAC ONEPlus Power Conditioned UPSs, which have a perfect ground reference, longer lasting and more reliable batteries, and a 5 Year Warranty (2 Yrs on Batteries).
