Why wont my ipod touch turn on i turned it off and it wont come o

its not just out of power?

Connect the iPod to different computers and let it charge for a while. Also, as it's booting w/ the apple logo, press the menu button to force it to recovery mode. That may let you restore it. If all of that fails on any of the computers, you have a broken logic board. You can try to replace the part yourself, it is available on any auction website. There is an iPod touch Repair service that can fix it for you, but if you're a little tech savy you should use an iPod repair guide that teaches you how to do the repair yourself.

Plug the damn thing in and let it recharge fully for a few hours.  The green battery icon will pop up on the screen to show you its recharging.  After your done charging try holding down on the power button again.  If you still get nothing, then your fuc..d and need a new battery, but the bastards at Apple have sealed the thing up tighter than a virgins legs and if you crack this nut open, then you will void the warranty.  So, if your within your 1 year Apple warranty, just take the thing back to Best Buy or the Apple Store and tell them the battery won't hold a charge.  They will give you a brand spankin new ipod in exchange.
