In a statement on the Sony support site for Vaio laptops, Sony posted a notice from Mike Lucas, senior vice president of Vaio for Sony, stating " Recently, we became aware of a potential issue affecting certain units within the VPCF11 and VPCCW2 series of notebook PCs."
Lucas also explains "In rare instances, these notebook computers may overheat due to a potential malfunction of the internal temperature management system, resulting in deformation of the product's keyboard or external casing, and a potential burn hazard to consumers.
The heat management system in the BIOS of affected Vaio laptops is not functioning properly and can cause the system to run hot. The BIOS for the Vaio laptops was developed by a third party, and customized for Sony by a separate third party, but Sony tested it on the Vaio platform prior to making it available.
Sony has received nearly 40 reported cases of Vaio laptops overheating to the point that the casing becomes deformed. While there are no reports of fires or burns caused by the overheating issue, Sony warns that it is a possibility.
To resolve the problem, Sony has developed a firmware update for the BIOS. Sony is directing users with affected Vaio laptops to apply the update to prevent overheating issues. The Sony statement also suggests "If you have any questions or need additional assistance with the firmware update installation, call Sony technical support at (866) 496-7669 for assistance."
