Gateway is taking advantage of Sony\u2019s battery-replacement program and will exchange approximately 35,000 of its consumers\u2019 batteries, it said Tuesday.The exchange program covers batteries that began shipping in September 2005 with laptop PC models CX200, CX210, E100M, M250, M255, M280, M285, M465, M685, MP8708, NX260, NX510, NX560, NX860, NX100, MX1025, MX6918b and MX1020j, the company said in a statement. Most were sold through Gateway\u2019s Internet shop. Full details can be found online. The battery cells are thought to contain metallic particles, which under certain circumstances could cause a short circuit, resulting in the battery catching fire. About 9.6 million battery packs are thought to contain the cells, and about 8 million have already been recalled or offered for voluntary replacement by laptop makers.Sony plans later Tuesday to offer more details of the problems that have hit its battery business. The recalls and replacements will cost the company about 51 billion yen (US$427 million).By Martyn Williams, IDG News Service (Tokyo Bureau)Follow CIO.com\u2019s ongoing coverage of the battery recall story.Check out our CIO News Alerts and Tech Informer pages for more updated news coverage.
