Well, this isn't good. Sony's issued a warning that about half a million of its VAIO laptops are at risk of seriously overheating, and could even cause burns. The company says that the heat-monitoring chips of its VAIO F and C series laptops (which were launched in January) could be defective, causing them to overheat and physically warp. Sony says it's received about 40 total complaints about the issue, and that affected customers will be able to download a software fix or contact the company directly to have the laptop picked up for a repair.
