just received my z570 refurb today. Booted it up once, ran a few windows updates, put it into sleep and went to work. I came back later that evening and the z570 would not come out of sleep. I powered the system down and attempted to reboot. The system did not boot and now doesnt seem to be charging on the ac adapter. This is seriously dissapointing... if anyone has a quick fix for this ill try it... if not im packing this thing up and going to buy an asus.
