Lenovo has announced that eight of its ThinkPad notebooks have passed military-standards for ruggedization, making them not only resistant to pressure, humidity, temperature, dust and vibration, but to a greater extent than some "mil-spec" rivals.

The ThinkPad X200, X301, X200s, X200 Tablet, T400, T500, R400 and SL300 all passed durability tests despite not being specifically marketed as ruggedized models.

Lenovo are crediting their Active Protection System (which parks the hard-drive automatically if the laptop drops), roll-cage, shock-mounted hard-drive and spill-resistant keyboard for the successes.

The tests covered: Low Pressure - Tests operation at 15,000 feet
Humidity - Cycles 95 percent humidity through the environment
Vibration (operational and non-operational) - Jostles and jolts the laptops to make sure they can withstand shocks
High Temperature - Simulates high heat conditions by baking the laptop up to 140 degrees
Low Temperature - Tests operation at minus 4 degrees
Temperature Shock - Fluctuates between minus 4 and up to 140 degrees to test operation
Dust - Blows dust for an extended amount of time

To coincide with the testing results, Lenovo are adding a high brightness, wide angle screen option to the ThinkPad T400 range, making it four-times brighter than previous displays and, thanks to an anti-glare coating, usable in direct-sunlight.
