Apple Admits Early Nanos Overheat
August 20, 2008: If you still have a first-generation iPod nano -- they came out in 2005 -- you may want to keep a closer eye on it, though Apple says the problem with them only occurs in "very rare cases."
And that problem is overheating, which is to say smoke and sparks due to battery problems. Japan's Ministry of Economy, Trade, and Industry is investigating three nano overheating incidents that resulted in minor damage, and it was the reports out of Japan that brought Apple to release a statement on the issue, CNET reports.
In a statement quoted by CNET, Apple said it has determined that "in very rare cases batteries in first-generation iPod nanos sold between September 2005 and December 2006 can overheat, causing failure and deformation of the iPod nano. Apple has received very few reports of such incidents (less than 0.001 percent of first generation iPod nano units), which have been traced back to a single battery supplier. There have been no reports of serious injuries or property damage, and no reports of incidents for any other iPod nano model."
If you find your first-generation nano running too hot, you can talk to AppleCare to get a new one.
