    Thanks for the response. I checked the fuse and its fine. The twin batteries test at 4 and 6 volts and the battery connections are fine. My house circuits are fine and still no lights on the machine. I can understand if the unit doesn't have enough juice to power on, but I can't even get a light on! Any other suggestions would be appreciated?

    regards Chris

Hello Chris,

I have a similar unit and there is a fuse inside that can blow. Mine did. It worked again after replacing the fuse.

Another option...check the battery connections.

Another option...are the batteries getting old? If so, when they won't reach a certain level of charge the unit will not power on.

Finally, make sure you don't have a blow fuse or popped circuit braker in your home.

Hope this helps?

APC UPS 1500 w/full load forces immediate reboot at pwr failure


With a 980watt load the run time is only 7 minutes on a brand new battery. If you have the system on full load your run time will be much less and it has likely damaged the battery. here is the APC web site page for your model. If you are running that much equipment I think you need either a bigger UPS or another 1500 and spread the load out.

APC Smart-UPS 1000VA UPS System calibation problem

If battery charge indicator is flashing it should be UPS calibration issue, If all the LED indicator is light up in the front panel and UPS still can go online on battery mode you just need to replace the board on the front panel and the light will just back to normal state.

APC Smart-UPS 1000VA is powered on but not working

Try turning the unit off for a little while, unplug it from the source even. afer about 5 minutes plug it back in and try it again. You may have a bad battery, how old is the unit. UPS batteries should be changed out every 3 year's, max every 5 year's if you want good reliability. At 5 years you are taking a chance.
