SOURCE: APC Smart UPS 3000VA - Dead UPS

ok how long you brought the ups and how long you had not start the the ups usaully ups is power dead change the battery and try to power up it should work be sure that all connection is connect properly before power up the ups.. if the ups doest work that will be the mainboard problem you hav to call for vedor to repair the unit.. yes these fuse for the ups but it unlikely to be blown so should worry of the fuse it self.. change of battery come with different spefc for the ups.. eg su3000rmi3u, sua3000rmi3u, su3000rmxl3u --- battery replacement is 8 pcs of 12v 7ah. sua3000rmi2u-- 6 pcs of 12v 7ah or 8 pcs 12v 5ah. su3000rminet-- 4 pcs 12v 17ah,

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: APC BP650S - will not turn on

validata, First things first!!! take the zero volts UPS battery out to your car and jumper charge it with your jumper cables! charge it for 5 to 10 minutes and disconnect it and then measure it to see what the voltage is!!! Is it 9v or 0v or 11.3v or what??? You must verify that you have a battery that can accept charging current and also be able to source at least 1.5amps and not have a significant drop in voltage when battery has a load across it! Use two 25ohm 25w wire wound resistors in parallel for a load of just under 1 amp. if terminal voltage falls off more than 1 volt, try charging for i hour and repeat load test. 12fixlouie

There is a hideous whistle coming out of the unit! We can't stop it by removing all devices that are plugged into it or by pushing the round button on the front. The overload light is illuminated but...


Hello,

This sounds like the gel cell battery in the unit is dead. The battery life usually is about 2-3 years and then it needs to be replaced. The BX900 UPS uses qty 2 of the 12volt 7amp hour gel cell batteries. You should be able to get them from your local battery wholesale business or computer store, even Radio Shack. The replacement batteries should run about $40-50 To replace them just open the cover and unplug the old batteries and plug in the new set.

I hope this helps, if so please rate our solution.

Acer Aspire 7004 wmsi Will not start.


When you press the power button does anything happen? such as lights or LED's illuminate?

You could try the following -

1. Make sure there is nothing plugged into the computer (USB devices or memory cards etc etc).

2. Remove the power cable & the battery

3. Press the power button for 30 seconds

4. Insert the charger but not the battery and try and start it up.

If that doesnt work check the USB ports for damage and the port where the charger is plugged in aswell.

If they are damaged or it still wont start it will probably need repairing.
