The new Toughbook 54 laptop from Panasonic uses the latest advances to create a laptop two pounds lighter and half an inch thinner than the competition. It features a spill-resistant, full magnesium alloy design, hard drive heater, backlit keyboard and is available in four different models to suit every need. The Toughbook 54 has a wide range of integrated options such as dedicated GPS, 4G LTE mobile broadband with satellite GPS, antenna pass-through, and insertable and contactless Smart card readers. It is the only semi-rugged laptop that offers an optional second battery, allowing hot swap battery replacement without the need to shut down or hibernate. It is also the only laptop in its class to offer dual drives, another feature that makes the Toughbook 54 one of the most versatile and advanced semi-rugged notebooks on the market.
