Sony says 535,000 laptops at risk of overheating

A bug in the laptop BIOS means more than half a million laptops could overheat

More than half a million Sony laptops sold this year contain a software bug that could lead them to overheat, the company said Wednesday.

Sony has recorded 39 cases of overheating among Vaio F and C series laptops that have been on sale since January. In some cases the overheating has led the laptop case to deform.

A bug in the heat management system of the BIOS software is to blame. Sony is asking users to either update the software themselves or return their laptops so it can apply the update.

The fault affects 535,000 computers although Sony is asking a total of 646,000 owners to update their machines. The additional 111,000 machines are susceptible to several less serious problems that have also been found in the software, said Sony.

BIOS is present in every PC and runs below the operating system, controlling the most basic functions of the computer and interaction between major components. It's usually invisible to users except for a BIOS start-up message that is typically seen when a PC boots.

Sony didn't write the BIOS in the affected computers. It sourced it from a third party and had it customized for Vaio laptops by a different third-party supplier, the company said. But Sony did test it before installing it in the machines.

The problem affects machines sold both in Japan and the rest of the world.

Japanese models with the problem are the VPCF119FJ/BI, VPCF118FJ/W, VPCF117FJ/W, VPCCW29FJ/W, VPCCW28FJ/P, VPCCW28FJ/R, VPCCW28FJ/W, VPCF11AFJ, VPCF11AGJ, VPCF11AHJ, VPCF11ZHJ, VPCCW2AFJ, and VPCCW2AHJ.

Affected models sold outside Japan are the VPCCW25FG/B, VPCCW25FG/P and VPCCW25FG/W.

It’s perfect for mobile workers. Just take it out — it’s small enough to sit anywhere — turn it on, load a sheet of paper, and start printing.
