The 5th generation 30 GB iPod, known informally as the iPod video, was manufactured between 2005 and 2007. IPods last for years, and while yours may still be going strong, one of the early signs of a malfunctioning iPod is difficulty turning it off. In theory, the device turns off at the push of a button, but sometimes this doesn’t work. You may need to do a soft reset to turn it off. Don’t worry, it won’t harm your data.
