[QUOTE="SeyR, post: 1681238, member: 361879"] My issue is similar, but not triggered by a phone. I'm getting the message when I plug in an unpowered 2.5" external harddrive. I have two such HDs, 3 cables, all cause the pop-up. I am fairly certain I know what caused it too: I had a powered External USB hub which stopped working when I accidentally plugged a 12w power supply into it when it wanted a 3w. The 2 HDs in combination plugged into a single USB port via said Hub, no longer powered, is I think what caused the overdraw. Because I use this machine for my work and NEED those harddrives, I'm in a real bind. I will try the 3 methods I read above: 1. Leave it unplugged and off overnight. 2. Unplug it and let the battery drain. 3. Reset SMC. If anyone else has any suggestions given the unique way I triggered this thing that'd be great. I'm slightly concerned I may have accidentally sent some kind of power-surge through my electronics :(. [/QUOTE]
