Mike Abaro, senior vice president of Sony's VAIO laptop division, wrote a letter saying a bad wiring job is potentially affecting four VAIO notebook models: VGN-TZ100 series, VGN TZ200 series, VGN-TZ300 series
and VGN-TZ2000 series. He asks users of those models to visit Sony's support site to determine whether their notebook needs to be sent in for inspection.
