On taxi out we were planning Runway 22L and received Runway 28R A9; T; N; B. Hurry up and get in front of the 767 under tow. Just as I was looking at the taxi diagram; iPad went blank in the power save mode. I continued while trying to get the iPad back up and turned on Bravo instead going to Tango. Co-pilot's head went down to change runway in the box. About the time I noticed we were on the wrong taxiway; so did Ground. We went down to A13 and back around to get on Tango.
