Alternating green and orange light with constant beeps

Verify that the usb to ups cable is pluggled in properly. Also you may not have a good ground. Disconnect the ups and plug it in another outlet to test with nothing else plugged into it, to see if it still beeps. You can also try and upgrade the ups software from apc.com

What does it mean by the beep sound from the UPS ES 350 unit?

Ok, 3-4 years is a much as you can expect from an ups battery so replacement is indicated. The beeps are letting you know the battery is not able to keep up with demand. So either you have recently added to the system or the battery/s failing.

I found this on the APC website;
Question: What would cause a Back-UPS Pro, a Back-UPS Pro USB, a Back-UPS RS, a Back-UPS CS, a Back-UPS LS, or A Back-UPS XS to beep once every 5 seconds with no output power?
Answer: One beep every 5 seconds is an indication that the UPS has entered what is called "Low Voltage Sleepmode".
The Back-UPS product has transferred to battery power due to a low voltage condition at the wall. The Back-UPS has remained Onbattery until its runtime was totally exhausted, however, there was still enough voltage present at the wall to trickle charge the battery.

This is considered to be a normal operating state. When the voltage returns to normal the Back-UPS will wake up and restore power to the battery outlets.

Take off the bottom cover and make sure the battery is connected (both terminals).
Plug the unit into a wall outlet.
Press the power button to turn it on. Leave it plugged in for 8 hours to charge the battery. Do this with nothing plugged into the unit.

Done.

Green light flashes with a constant buzzing sound but it still powers other equipment? Do i need to replace the battery on the APC UPS-ES 500

It sounds like you need a new battery. If the APC is more than 3 years old, that is likely the problem. You can get a new battery from http://www.batteryinternational.com/apc-backups-es-be500u-ups-battery-ups-batteries-f2.html

APC ES-350 won't turn on; all I see is a blinking light.

Try looking for a small circuit breaker on the side that says "press to reset" - you could have tripped it accidentally when you unplugged the iPod. Also, try pressing and holding the UPS power switch for 10-15 seconds. That should force a power on as well.

APC ES350 strange noise

My solution was to unplug everything, hit the reset button, and then power the unit back up. The problem I found to be that I had my laser printer connected to the "surge + battery" side, and for some reason no laser printer can be connected to it.

A blinking green light is likely an indication that the internal battery is nearing the end of its usable life cycle. If it's over 3 years old this is likely the case. To test, plug something in to the battery outlets and pull the plug of the UPS from the wall. If you get a short runtime (or none at all) it's the battery. Batteries are under $20 and can be found here: http://www.batteryinternational.com/apc-backups-es-be350u-ups-battery-ups-batteries-f1.html
