Sony said in a statement it had shipped 25,905 of the Vaio Fit 11A in 52 countries since its launch.

Sony said three PCs had caught on fire around the battery pack, which was manufactured by Panasonic Corp. The company has also advised its users to stop using Vaio Fit 11A laptops as early as possible.

“Sony has identified that the non-removable battery packs provided by a third party supplier, included in (and limited to) VAIO Fit 11A released in February 2014 with listed model names could potentially malfunction and cause overheating, resulting in partial burns to the chassis of the PC,” the company said in a statement.
