The Satellite Z930 is the ultra light Ultrabook from Toshiba. Remarkably thin & light, youll float through the day with the 13.3" Z930. But dont let its size fool you. With a full set of ports, magnesium alloy build, & long hours battery life, its one heavyweight performer. The Z930 features a striking design with a magnesium alloy finish in dark silver with a brushed metal finish & metal accents on the hinges. A backlight tiled keyboard looks stylish & is ideal for working in darker conditions. A solid bottom plate & a streamlined rubber protective strip for the screen put the final touches on a clean, sleek design. The Z930 features a light, yet durable magnesium alloy casing that is reinforced with the honeycomb structure & internal strengthening that provide shock absorption, increased rigidity & resistance to flexing. This makes the laptops highly resistant to drops & shocks. Plus, the full-size LED backlight & spill-resistant keyboard withstands accidental fluid spills to give users enough time to shut down the laptop & protect data stored on the device.
