Military-Specification Testing & Extra Durability Features. Validates the ruggedness, durability, and quality of ThinkPad products by testing against eight parameters: high pressure, humidity, vibration, high temperature, temperature shock, low pressure (15,000 ft), low temperature, and dust. The 11e uses thicker plastic on the bezel with integrated webcam, for extra durability. The full-sized keyboard reduces gaps between keys by 60%,  so keys are less likely to be removed, and the advanced drainage system collects and diverts liquid away from circuitry through drainage hole in bottom.
Think Vantage Active Protection System (APS)For models with traditional hard drives, an accelerometer detects movement and stops the drive when a fall or similar event is detected. Rubber mounts are used for the hard disk drive (rather than rails) and the HDD connector is not rigidly attached to the board, so the connector absorbs shock and impact and protects against system damage.Social Networking FeaturesA low-light sensitive HD webcam, HD anti-glare display, HD microphone, and speakers, plus preloaded Skype™ application for video calls makes it a cinch for learning via social networks. LED activity lights on the top cover indicate at-a-glance status of wireless connectivity and power/sleep mode. Dolby® Advanced Audio™ v2 provides immersive surround sound and enhanced acoustics. Intel® HD graphics includes up to 100% increase in 3D and visual performance from previous generations.
