There’s a conspiracy theory that Steve Jobs wants you to buy a new iPod every 12 months. That may or may not be the case, but if your iPod is hosed, it doesn’t necessarily mean it’s time to put it out to pasture. Most iPods are user-fixable and you don’t need to be a total geek to make it work.
An iPod, no matter which version you have, is basically a self-contained, battery-operated, pocket-sized computer. All the components that a regular laptop has are represented: display, battery, storage, RAM, and logic board. This is what makes the iPod something easily fixable: the pieces are just scaled-down versions of their PC analogues, and are put together in the same basic way. This means if you can isolate your iPod’s problem, you can fix it.
