Dell's ATG series and Panasonic's ToughBooks provide the basis for rugged Linux laptops and tablets designed with harsh environments in mind, and their MIL-STD-810F compliance has been independently tested. The tests to which these systems are subjected (with no ill effects) include:

Common Name MIL-STD-810F Method ATG CF-19 CF-30 Vibration Method 514, Procedure I, Category 24 (Minimum Integrity Test), Category 20 (Ground Vehicles) Drop Test Method 516.5, Procedure IV (Transit Drop Test)   Dust Resistance Method 510.4, Procedure I (Dust) [1] Humidity Method 507.4 (Aggravated) Water Resistance Method 506.4, Procedure III (Drip)   Altitude Method 500.4, Procedure I (Storage) and II (Operation) 10K ft [2] 15K ft [3] High Temperature Method 501.4, Procedures I (Storage) and Procedure II (Operation)   Low Temperature Method 502.4, Procedures I (Storage) and II (Operation)   Thermal Shock Method 503.4   [1] The ATG met Method 510.4, Proc. I for all D-module options (2nd HDD, 2nd battery, Air Bay) except optical drives. [2] Altitude (Method 500.4 Low Pressure, Proc. I; Operational up to 10,000 feet). [3] The altitude level was 15,000 feet (the highest equivalent altitude given within MIL-STD-810F for cargo pressures of military aircraft). Panasonic describes the tests their ToughBooks go through in the following ways:

• Vibration - Operated during simulation of 1000 miles of transportation in a ground vehicle, and operated after being subjected to higher levels of vibration while off.
• Drop test - Dropped (while off) from 36" onto all faces, edges, and corners onto a piece of 2"-thick plywood over a steel plate over concrete.
• Dust resistance - Dusted with silica flour. No moving parts, including the keyboard, were bound or blocked by the dust, and no contacts or relays malfunctioned.
• Humidity - Operated after being subjected to 95% humidity at temperatures cycling between 86°F and 140°F.
• Water resistance - Water dripped onto running laptop with LCD open (and ports closed) for 15 minutes.
• Altitude - Operated at 15000 ft and after being stored at 15000 ft.
• High temperature - Operated at 140°F and operated after being subjected to 160°F.
• Low temperature - Operated at -20°F and operated after being subjected to -60°F.
• Thermal shock - Operated after cycling repeatedly between 205°F and -60°F.

The features that these rugged Linux laptops use to protect themselves from harsh environments include:

• Magnesium casing
• Shock-mounted hard drives
• Vibration-resistant LCDs protected by an overlay panel
• Flexible internal connectors
• Sealed, spill-resistant keyboard and touchpad
• Sealed ports and PC card slots

Panasonic's semi-rugged laptops incorporate the most important of these features: the magnesium alloy case and a shock-mounted hard drive.
