Sony isn't taking any chances with potentially defective battery packs found in Vaio Fit 11A laptops
Sony is warning owners of Vaio Fit 11A laptops that the non-removable battery packs provided by a third party supplier could potentially present a burn hazard. In certain model Vaio Fit 11A notebooks released in February 2014, the built-in battery could malfunction and overheat, resulting in partial burns to the chassis and the PC. Since it's a non-removable battery, your only option is to stop using the PC and disconnect it from the AC adapter.
A news alert on Sony's U.K. portal identifies a dozen serial numbers of affected models in Europe, however this doesn't appear to limited to just one region. On a separate website, Sony today said it's stil identifying affected PCs by serial numbers and developing a program to repair or replace potentially defective units.
"We expect to post a program announcement with details within two weeks," Sony said. "In the meantime, as safety is our primary concern, we ask again that you please refrain from using the below-listed model until you further hear from us in the program announcement."
The model number Sony references in its statement is SVF11N13CXS.
According to a report in The Wall Street Journal, Sony said it received three reports of batteries overheating and causing partial burns to Vaio PCs. The first happened in Japan on March 19, followed by another incident in Hong Kong on March 30 and in China on April 8.
