UPS Shut down
Hi - I own a DCP UPS, and it's been with me for 2.5 years now. Recently (this happened twice) whenever the power shuts down, the UPS makes a screeching noise every 2 seconds (compared with every 5 seconds earlier), the orange battery light flickers on and off, and five seconds later, it shuts down with the computer after the orange light turns red (indicating an emergency).
However, when I switched on the UPS, waited for two minutes, then WITHOUT switching on the computer shut the power off, it reacts normally (ie turns to battery power without a hitch).
So does this mean that it is unable to bear battery power while the computer is on? And if so, does this mean that I should discard this one and get it replaced? And another final thing - until I do so, should I disconnect this one from the PC in case it may adversely affect the power supply of the CPU?
