The company has identified 25,905 of the computers worldwide shipped since it first went on sale in February. About 3,600 were sold in Japan, 2,000 in China, 7,000 in Europe, 5,600 in Latin America, and 500 in the U.S. Nearly 7,000 were sold in Asia-Pacific, excluding Japan and China.
"It has come to our attention that some of the internal, non-removable battery packs provided to us by a third party supplier and included in VAIO Fit 11A released in February 2014 have the potential to overheat resulting in partial burns to the housing of the PC," noted the press release published on Sony's website on Friday.
The first incident was reported in Japan on 19 March, followed by similar incidents on 30 March in Hong Kong and on 8 April in China. Sony says that it has stopped selling the product at the beginning of this month and is asking customers to stop using their Vaio Fit 11A laptop as soon as possible.
In another statement on its website, Sony has revealed the serial number of the affected European products. Sony is advising affected customers to leave their details on the page and wait for the company to get back. The Vaio Fit 11A uses a non-removable battery, which means the entire product will have to be replaced.
According to a report by WSJ, a Panasonic spokeswoman confirmed the company had provided the batteries to Sony under an outsourcing contract. But she did not comment to what other computer manufacturers had received the similar Panasonic batteries.Catch the latest from the Consumer Electronics Show on Gadgets 360, at our CES 2026 hub.
