I have a computer that is plugged into an APC SC1500, the online indicator is green and the self checks are ok, but twice now when the power has gone down so has the computer. It is like its not even plugged in to the UPS - but it physically is. Any idea where I should look for the problem at?

Unplug your UPS from the wall. If the UPS shuts down you must replace the batteries please call me for free tech support at Gruber Power Services 800-658-5883 ext 256 and ask for Eric

These beep error codes may help you. 1. Four beeps every 30 seconds (On Battery LEDwill be illuminated) This alarm indicates that the Battery Power Suppliedoutlets are now supplying battery power as opposed to power from the utility.If the UPS determines that the input utility power is unsafe for your computerequipment, the UPS will switch to battery power. Note: Ifthe power disturbance is brief, you may only hear one or two beeps.
2. Continuous Beeping (On Battery LED will beilluminated) This alarm indicates that a Low Battery condition hasbeen reached and that the UPS will soon shutdown. Once the UPS transfers to OnBattery operation, it can only stay on battery for a limited amount of time.The UPS will sound this alarm about two minutes before the batteries aretotally exhausted. Once exhausted, the UPS will shutdown and turn off itsoutput power to your equipment. If you hear this tone you should immediatelyshutdown your computer to prevent data loss or corruption.
3. Continuous Beeps for 30 seconds (Back UPSOFFICE 250 and 280 ONLY) This alarm indicates the unit has detected an Overloadcondition after it has performed a self-test during start-up.
4. Continuous Two-Tone Beep This alarm indicates a severe Overload was detectedwhile the unit was on-battery operation. This tone will continue to sound untilthe unit shuts down.
5. Continuous Tone (On Battery LED will beflashing) This alarm indicates that the battery-powered outletsare overloaded.
6. Continuous Tone (On Line and On Battery LEDsflashing) Back UPS OFFICE 350, 400, and 500 ONLY This alarm indicates that an internal UPS fault hasoccurred.
the apc ups performs a self test when ever it is powered on.... it should complete the process in 10 to 20 second but if it does not, then there is something wrong with ups.. try to get it checked...
power off wall plugged switch and check the battery side online. of not pls check the power out of the ups is enough to work the phone system, also need to check the battery voltages with multi meter
More than likely it is the battery. These units simply test the voltage during the self test, and, although not typical, the battery voltage could be good without a load, but fail with a load. 3 years is generally the life span of SLA batteries. Replacement batteries are fairly inexpensive and can be found at: http://batteryinternational.com/ups-batteries-apc-batteries.html
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
