CyberPower SE450G1-R Battery Back-Up System UPS

My EC650LCD worked fine for one year and then something went wrong because the ECO light was blinking all the time and there was not power coming out from the ECO controlled outlets. I contacted CyberPower and described the situation and they sent me a replacement UPS unit with no questions asked. After I received the replacement UPS unit, I plugged it not the wall and let it charge for 8+ hours. Then I pressed the power button and the unit turned on. However the ECO light was off. Then I followed the steps to activate the ECO feature and was able to activate it but the ECO light was blinking same as on my old unit. I read the instructions more carefully, so I turned off the UPS unit and unplugged it from the wall, then I connected my computer and the monitor to the ECO controlled outlets, then I plugged the UPS unit to the wall, then I pressed the UPS unit power switch and attempted to power on my computer and monitor but neither of them responded. I read the instruction further and they indicated that if the ECO light was blinking, it meant that the UPS unit did not detect the computer. At this point I stopped and scratched my head. How could the UPS unit detect my computer if the ECO light was blinking? If the ECO light was blinking it meant that there was not power coming out from the ECO controlled outlets, so how could I turn on my computer so that the UPS unit detected it if there was no power on the ECO controlled outlets? I have to mention that I kept the UPS’ unit USB cable connected between my computer and the UPS unit so that it could “detect” my computer but that did not help. After going through this entire ordeal with the new UPS unit, it made me wonder if my original CyberPower unit was still good and that it stopped detecting my computer because at some point in time, I powered my computer off. So I connected the old unit to the wall, powered it on and ran it through “Power Panel Personal” and the old unit came out excellent. So I repeated the same steps with the old unit, and I had the same results than with the new one. The old unit was good but it could not detect my computer because it was off because the ECO light was blinking and therefore there was no power on the ECO controlled outlets. Is this issue an EC650LCD design flaw? Am I following the steps wrongly? As a bonus, I tried something not so elegant to get ECO control system to work. I connected my monitor and computer to the UPS unit surge protector outlets, I powered on my computer on and when it was just beginning to boot, the UPS ECO light switched from blinking to steady, I quickly unplugged the computer form the surge protector outlet and swapped it to one of the ECO controlled outlets and was able to get my computer and my monitor running under ECO controlled mode. As you may understand, I do not recommend the CyberPower EC650LCD UPS unit. I’ll keep both UPS units as surge protectors. As for the Lead Acid Batteries, they might still be useful for something else since they are fully charged and are expensive.
