I have an APC XS1300. One year old. Very few

This "Event 9" means that the UPS has has 9 events. It could be going on battery or a high input or output. Either way we can reset it. You will have to turn on the UPS. Unplug it from the wall and also unplug the battery. When all is unpluged push and hold the power button for a few seconds. This is the reset. once done hookup the batteries and plug in the ups. All should be better. Event 9 will be gone. Till next time..... When it will say "Event 10"

how much current is your computer using?

Hi,first you need to check if fuse has not been blown out.Because when POWER comes back after an outage there is a surge voltage flowing through electrical lines.It is advisable that when their is a POWER outage you have to turn off your FUSE box or SAFETY box to make sure that it won'tdamage appliances when POWER comes back>Technically when POWER SOURCE or SUPPLY has been shut off for a period of time.When POWER is back, expectantly there is an abnormal flow of current/line; current will not be as stable until a period of time..AC current behaves like a wave,values changes from time to time especially when POWER SOURCE has just been TURNED ON..So better turn off FUSE BOX when experiencing POWER OUTAGE so that when power comes back SURGE VOLTAGE wont flow within the circuit>Hope this helps..

Read your APC battery back up manual, it will guide you how to use your APC properly! Also use a Heavy duty AVR that will protect your computer from electrical fluctuation. Have a nice day!

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

The Back-UPS is fairly straight-forward. The 9-pin connector (at the top of the back) is a serial port (RS-232) for the UPS data (when connected to a computer it will shut down the computer safely during a power outage). The next plugs are RJ-11 telephone jacks; the cord from the jack (wall) goes in on the left (some models have RJ-45 for network protection). The battery protected outlets are the three surrounded by black paint. The other three provide surge-protection only. Do not plug items like printers and scanners into the outlets that provide battery protection.

I hope this helps.

How old is unit? UPS is a Battery that is charged from power outlet.It maintains voltage when computers are plug into it so fluctuations in current don't spike or wane.On a Power Failure the UPS supplies all the power by using the battery and an inverter.If your units batteries are not charging you need to replace them.In most cases it is not cost effective.Do some more test before you replace it.Good Luck.

you will try to change the fuse in ups

The basic design hasn't changed since day one...there maybe a few more bells and whistles now, If the unit is working fine...change the battery...and use the unit...BTW..just for your info large UPS'S are kept in service for 10-15 years or longer...hope this helps

Try upgrading the firmware through the Routers Web Interface , and see if this will fix the problem otherwise the only other way around it is to do what you are currently doing and unplug and plug it back in, perhaps the AP was damaged as a result of a power surge , if the problem persists best bet is to buy a new one.

Goodluck!
