If "dead" means that the iPod Touch's battery ran low or has been used up completely, use your Apple charger to charge it. When it has fully charged, press the power button, and your iPod Touch should be working again. If you always had full battery or high battery, or you have tried the above method but your iPod Touch still doesn't work, try resetting it. If that doesn't work, your iPod Touch may truly be "dead".
