Sony recalled notebook computers due to burn hazard. 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. The recalled notebook computer models are the VAIO VGN-TZ100 series, VGN-TZ200 series, VGN-TZ300 series and VGN-TZ2000 series. The computers' screen size is about 11.1 measured diagonally. Not all units are affected.
