I have a UPS Backup 650, part BN650 M1 that recently developed a flashing green alternating with yellow light. It seems to work fine otherwise. I replaced the battery, no change. Does anyone know what this means? The flashing green alternates with a flashing yellow. I cannot find any info on this mode. When I first turn on, it is flashing green and about 20 sec later, it turns green and starts the flashing green/yello.
