Sony has announced a recall of 535,000 Vaio laptop computers following reports of issues with overheating. Sony Vaio VPCF11 and VPCCW2 series computers are included in the recall. According to the company, it's software, not battery issues, at fault.

Sony has noted 39 cases of overheating among the laptops. Reportedly, the fault lies in the system's internal temperature management system. A BIOS change has been made to address the issue.

Customers are encouraged to either update their BIOS themselves ASAP, or to return the systems to Sony so the update can be applied. The update can be found here.

Updating the BIOS on modern computers is quite easy. Still, many may prefer to have a professional apply the update. The Sony statement also adds "If you have any questions or need additional assistance with the firmware update installation, call Sony technical support at (866) 496-7669 for assistance."
