Is the UPS plugged in? Are there any lit LEDs on the front of the UPS? Did you replace the batteries in while the UPS was plugged in? Make sure that the battery you placed into the UPS is a good battery.
Hope this helps. If you would like more assistance please give me a call: 407.380.9200.
Probably the battery of UPS. you can contact the manufacturer for the replacement of battery. Also please check the manual if you can replace it yourself.
It could be the power built in power supply, but I would check the battery first.
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.

Friend have you plug and switch the ups properly, If so then check that you have also plug your computer pin properly into a ups. If this is also right then there might been problem in a UPS charging or in ups. It might also be a system fault. Just check out the system fault by applying the direct connection to the socket. If this solve your problem then check out all the procedure of ups to work and if this does not solve problem repair ups or charge it properly. If the ups is also not charged then it also make a problem to start for sometime.

Plug it into a wall, turn the beeps to off, plug in a desk or table lamp, unplug the UPS from the wall and let it drain down to nothing with the lamp on. You may want to time this. This is how you break in a new battery too.
After its completely dead, unplug the lamp, plug it into the wall outlet and let it charge backup again.
You should not get the error message.
Now, if the error message is from your PC and you have the USB cable attached. Remove the USB cable from the UPS to the PC. using Add/Remove programs in Control Panel remove teh UPS software, have the UPS disc on hand first. Reboot. when you get your desktop, install the UPS software and do not attach the USB cable until told to do so or until the installation is complete and you have rebooted the PC. Reboot after installation whether it tells you to or not. During the system restart, plug the USB cable back in. You should be fine. If you continue to see this reporting error, download a program update for you UPS.
