Earlier this week I was afraid that my jukebox had died, since it was unable to power on, and displayed an alarming sounding message about a hardware failure. Since I knew that I really wanted to have music for the drive out to P-burgh and back (once you're out of range of my hometown stations, it's nothing but country), I thought that I might have to replace it with something, perhaps an iPod. The jukebox is bulky and slow to start, but as long as it worked it didn't seem worth replacing. But if it was toast... on the other hand, I didn't really want to shell out the money, or figure out how to deal with Apple's preferred format.
But I went to the website, looked at the FAQ, and there was the explanation: you get this message when the rechargable battery is dead. So, a quick trip to Nerd Shack and it was back in operation. So yay for FAQs, and boo for unfriendly error messages.
