In both Japan and the States, Sony has issued an official recall notice for its VAIO TZ-series ultra-portable notebooks that are in danger of overheating.

With 73,000 models affected, the company says consumers should stop using recalled products immediately.

The hazard is described as "irregularly positioned wires near the computer's hinge and/or a dislodged screw inside the hinge can cause a short circuit and overheating. This poses a burn hazard to consumers".

There have been 15 reports of overheating, including one consumer who suffered a minor burn.

The recalled notebook computer models are the VAIO VGN-TZ100 series, VGN-TZ200 series, VGN-TZ300 series and VGN-TZ2000 series.
