What to do if my CyberPower CP1000PFCLCD will not turn on?

If your CyberPower UPS doesn't turn on, there are several possible reasons. First, the on/off switch might be preventing rapid cycling. Turn the UPS off, wait 10 seconds, and then turn it back on. Ensure the UPS is connected to a working 110/120V 60Hz outlet. Also, the USB cable must be connected to the UPS unit and an open USB / serial port on the back of the computer, using the cable that came with the unit.
