<A HREF="http://www.cio.com/blog_view.html?CID=25398">Acer is in talks with Sony</A> over joining its voluntary laptop PC battery recall, but said Acer users haven't reported any problems so far. Acer has not received any complaints from users over laptops overheating or catching fire. Sony's battery woes started in August when Dell recalled 4.1 million laptop computer batteries due to a potential fire hazard caused by Sony-made lithium-ion battery cells damaged during production. Other companies soon followed Dell's lead, including Apple Computer, Lenovo Group and Toshiba.
