On Tuesday, Sony said it would recall 60,000 of its notebook computer batteries in Japan, adding its own name to the list of PC makers recalling Sony-made batteries.
Sony"s move, which was expected, comes a day after Sharp announced its recall of 28,000 battery packs.
Previous notebook battery recalls were issued by Dell and Apple Computer in August for specific laptop models containing Sony batteries, after it was discovered that some batteries were overheating or exploding, causing fires even when the machines were turned off. At the time, Sony said the issue was confined to Dell and Apple computers, and the problem was attributed to a potential short circuit caused by tiny shards of metal left over in the battery cells from the manufacturing process.
Toshiba announced that it, too, would be recalling 830,000 laptop computer batteries, while Dell increased the amount of laptop battery recalls from 4.1 million to 4.2 million. Lenovo announced a recall of 526,000 laptop batteries, after a Lenovo ThinkPad T43 caught fire at the Los Angeles International Airport.
