If you have an iPod mini, go to Extras --> Main Menu ---> Sleep ON. Then go to the main menu and the sleep option will be there.
Any answers to my question?
I don't have an iPod so this might be offbase but if that is the case, it would probably be the PC scenario. To keep it on 24/7 or not?? You would think that it would be good to turn it off when not in use to give it a rest but that might not be a good thing. When you turn it on, there is a surge that goes through it and can hurt the components. I would assume that the same can be said for the iPod/battery. The surge, albeit much smaller than a PC, can put a drain on your battery. Maybe this is what they were talking about. Either way, I would just test it out for yourself. 1 time, try putting it to sleep. Another time, try turning it off. See what happens.
