The Satellite M645-S4080 14-inch Notebook Computer from Toshiba is a portable computer, built with performance in mind. The system's 14" widescreen display features a 16:9 aspect ratio and the ability to display 720p video at native resolution. The LED backlight uses less energy and has fewer environmental toxins than a traditional CCFL lamp, while at the same time delivering superior image quality and evenly distributed lighting without the need for warm-up time.
