Question about APC Back-UPS ES 350 - UPS ( external ) - 350 VA - UPS battery lead acid - 6 output connector(s) (NEWITEM13161548) UPS System

Open Question

APC Back-UPS ES 350 makes a screeching noise and shuts off. It doesn't shut down the computer properly and really gives no warning. I have came home several times to find my computer off without proper shutdown but didn't know why. Finally I was here when it happened, I assume it's a battery issue?

SOURCE: 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.

SOURCE: APC UPS no power

The unit might have a dead battery, blow fuse, or a bad board.
Your best bet is to talk to an APC rep. Worst case, APC has a trade in program, and can give you a discount on a new one.
Good luck.

SOURCE: 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.

SOURCE: green light flashes with a constant buzzing sound

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

SOURCE: APC external Backup battery is not working plz

Solution #1 is absolutly correct.......

But...keep something in mind. You also have a 50-50 chance that the inverter may have also gone...with the battery. So you could buy a new battery for $30.00 or you could by a new UPS for $65.00

So does this APC you have seem almost disposable?
The question is....if you buy a $30.00 battery and the unit does not work, then you buy a $65.00 UPS, how much did it actually cost you? Just consider that option.

How can you tell if the system is bad on apc back ups es 650


plug something (other then a computer)into it, turn the gadget on, then unplug the UPS. If the gadget continues active the UPS is OK. Generally after you have punched every button (circuit breakers). After that put a Volt/Ohm meter on the batteries (and the charging wires to check the charging curcuit is OK.

I hit the button to turn it on it will stay on for awhile and then it will start beeping really loudly an shut off


With your UPS turned off, unplug your PC and all other devices from the unit. Then turn the UPS on. If it still beeps and shuts off your UPS internal battery may need to be replaced or you have an internal UPS failure. Look for a red "battery alarm" light on the front of your UPS.

If the UPS does not shut down with all devices disconnected from it, Power off your monitor and look on the back of the monitor for a label which will tell you the amount of power it requires (probably 100 watts or less). Plug the monitor's AC power cord into your UPS and turn on your PC and monitor. With the UPS plugged into the AC line you are not using the internal battery and the UPS should remain on and your monitor should be working. If it shuts down you have an internal problem with the UPS.

Now unplug your UPS from the AC line (simulating a power failure) Your UPS is rated at 350 watts. Accordingly it should easily support the 100 watt load of your monitor. If the UPS continues to provide power to the monitor for 1 or 2 minutes down it's an indication that it's working properly and the COMBINED LOAD of your monitor. PC etc. when plugged into the UPS is exceeding the 350 watt capacity of the UPS. You will have to disconnect 1 or more devices from the UPS.

NOTE: Never plug a laser printer into an UPS.

If the UPS immeadiately shuts down after disconnecting it from the AC line with only the monitor plugged into it you have a bad battery.

UPS shuts off intermittently and beeps


More than likely it just needs a new battery. If the power is sagging (called a brownout) the UPS is trying to switch over to the battery to keep the power consistent. The beeping is probably a code that indicates there is an issue with low voltage on the battery. New batteries are around $20-25. Here's a link to the replacement battery: http://batteryinternational.com/apc-backups-es-be350es-ups-battery-ups-batteries-f1.html

Hope that helps.
