Hi AudiA1,
OK - you got me curious now with the mention of "the timer going back down from 5 minutes". what timer are you talking about? I do not recall a timer on the last two version on N 360 (the 2012 product/ version 6) had a timer that would count the Idle Time - buit I do not recall any other timer.
Culd you tell us whcih version of N 360 you are on (from the main page Support > About). If you already have mentioned it, I 'm sorry for missing it.
