Hello I have a Numeric brand UPS and it has worked flawlessly for nearly 4 years. Right now, a problem which is weird haunts the UPS. Whenever I shut down my PC, I switch off the UPS and pull out the UPS power cable. Now the UPS has 3 light indicators: Online, Fault and Battery to show when it is operating in those respective modes with online meaning that power is being received.
As of late even though I have switched off the UPS and after having removed the power cable, the online indicator still glows. Now I can't even hear the long beep when I turn on the UPS which says that it is switched on. Please help me in this. Thanks in advance.
