Engineered to endure spills and tumbles with rubberized edges and rounded corners for minimal drop impact, a spill-resistant keyboard and captive keys. Rigorously tested to withstand 76.2cm (30) drops onto steel, 121.92cm (48) drops onto plywood, thousands of 10.16cm (4) micro-drops, and tens of thousands of hinge cycles. The new Latitude 3120 has been tested more rigorously than ever for maximum endurance. Prevent drops with laser etching for enhanced grip on the front and back covers.
