I posted this on another thread but feel it is appropriate here in "tips and tricks...".
The SYNC toggle on the power bar is same as ACCOUNTS/ADVANCED SETUP/ACCOUNTS AND SYNC. There is a slider switch beside the words "ACCOUNTS AND SYNC", Slider says "OFF/ON". This is the switch within the ACCOUNTS App that does the same thing as the power bar SYNC. Change it in either place and the other switch follows the change you made.
