Sony posts patch to ease overheating Vaio risk

Gentlemen, recallibrate your thermal sensors

More than 500,000 Vaio notebooks around the world contain mis-callibrated temperature sensors that could allow the laptops to overheat, Sony has admitted.

The machines are part of the Vaio F and CW2 series, and have been on sale in Europe since January. Some 103,000 of them have been shipped into the region.

It's not clear how many of these have experience overheating, but Sony said it had received reports from 39 owners worldwide of high temperatures causing the machines' plastic shells to warp.

Having studied the problem, Sony has now posted Bios updates which correctly set the machines' sensors.

You can get the F-series update here, while the new firmware for the CW2 laptops can be downloaded here.

Not all Vaios in the F and CW2 series are affected by the problem - you can check whether your machine is by keying in its series number here. ®
