It took the recalls of Dell, Apple, Hitachi, Fujitsu, Lenovo and Toshiba Sony-branded laptop batteries for Sony to realize that there may be a problem. They will be recalling 90,000 of the batteries used in their Vaio series of laptop computers. The majority of which are in Japan and China.

Sony also said that they may have to revise their annual earnings outlook for this year because of the battery non-sense and also to compensate for a price cut for the PS3 in Japan. Damn, Sony. Looks like it may be a tough year.
