writes "Sony warns about a potential fire risk in some of its Vaio Fit 11A portable notebooks (the final model under the Vaio brand which was sold off in February). The company is asking customers to stop using this laptop model as soon as possible. Sony said it had received three reports of batteries overheating causing partial burns to Vaio computers. The first incident was in Japan on March 19, followed by similar incidents on March 30 in Hong Kong and April 8 in China. The company stopped selling the product at the beginning of this month, with nearly 26,000 units in the wild. The manufacturer and company responsible for the faulty batteries is Panasonic. A Panasonic spokeswoman confirmed the company had provided the batteries to Sony under an outsourcing contract. She declined to say which other computer makers had received Panasonic batteries, as such information is confidential. However, she said the batteries are customized according to clients' requirements and differ depending on client. She said Panasonic hadn't heard of any problems with batteries supplied to other clients. Sony said in a statement that it was identifying the affected computers by serial number and developing a program to repair or replace them. It said the company would provide details on its home page within two weeks."
