I have a Gateway FPO2185W which requires a soundbar for audio. I have the soundbar 2522277 but have no power cord.. I am not sure if the power cord is supposed to go from the sound bar and connect right into the power in audio on the monitor or just be plugged into an electrical outlet? it says it needs a 2.1 mm 12vDc 1.0 A DC out adapter.....but I can't seem to find the right one?? Any help would be appreciated. Sandy
