FYI from Apple: iPod's battery works best when iPod is at room temperature, generally near 20 °C, but you can use iPod anywhere between 10 °C and 35 °C (about 50 ºF to 95 ºF). If you have left iPod in the cold, let it warm up to room temperature before waking it from sleep. Otherwise, a low-battery icon may appear, and iPod will not wake from sleep. If after warming up, iPod does not wake from sleep, connect the power adapter, and press the Menu and Play/Pause buttons until the Apple logo appears. (noah, 12/13/2002 11:33:22 AM .)
