Lenovo has announced that no less than eight of its laptops have met military standards for semi-rugged computing. The lucky winners were the ThinkPad X200, X301, X200s Tablet, T400, T500, R400 and SL300. These laptops were subjected to a barrage of military specification tests and contain unique durability features.
The Tests
- 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
The Durability Features
- Active Protection System – Temporarily parks the hard drive when the laptop detects a fall or sudden movement via an air-bag like system
Roll Cage – Serves as a protective frame around the internal components where the data resides and processing takes place with an extra top cover roll cage on the ThinkPad X301 laptop
Shock Mounted Hard Drive – Offers extra protection around the hard drive to protect data
Spill Resistant Keyboard – Withstands spills of up to two fluid ounces on select laptops allowing liquid to drain beneath the keyboard
We all knew ThinkPads were durable, but a little extra confirmation doesn’t hurt
