ThinkPad T431s Features

Award-Winning Keyboard Further Enhanced for Windows 8
Full-sized and spill-resistant, the legendary ThinkPad ergonomic keyboard is renowned for its full array of keys, excellent feel, and TrackPoint® pointing device. And now it's optimized for Windows 8 with convenient multimedia buttons, LED status indicators, Function-lock capability, and immediate access to view apps. Plus, a larger, smooth TrackPad with 5-point click integration – indicated by subtle bumps and stripes – can be configured multiple ways through Settings. Available optional backlight makes working in dark environments effortless.
Weighs 3.6 lbs
The ThinkPad T431s is the thinnest and lightest model in our T Series. Weighing in at 3.6 lbs and less than 21 mm at its thickest point, it's smaller than the diameter of a nickel.
Robust Security Features Including Intel® vPro™
Intel® Anti-Theft protection (AT-p) adds an extra layer of security and manageability incorporated with Intel® vPro™ technology. Intel AT-p lets you activate hardware-based, client-side intelligence to secure your PC and data if it's lost or stolen. Plus, select ThinkPad models feature the Trusted Platform Module chip for encrypting data, Client Security Solution software, and an integrated Fingerprint Reader for a seamlessly integrated security package. Additional available security features include 32-byte pre-boot passwords and the ability to disable input/output ports at the BIOS level. Note: Not all models include all features as standard.
Ultradurable Construction & MIL-SPEC Tested
Innovative roll-cage technology adds extra strength and rigidity to the notebook shell and top cover (carbon fiber top with magnesium bottom for maximum strength without adding weight). Military-specification testing 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.
Dolby® Home Theater® v4
Increased audio clarity and maximized volume output without distortion — enjoy a crisp, clear immersive surround sound experience over built-in stereo speakers. All the power and nuance of the cinema, all the immediacy of live performance, now from your ThinkPad.
Superior Web Conferencing / Voice-Over IP (VOIP)-Optimized
Low-light sensitive 720p HD webcam with wide-angle viewing and face-tracking, dual noise cancelling microphones with configurations for crystal-clear private and conference mode VoIP meetings. Plus, convenient multimedia keys provide quick and easy access to microphone, speaker, and camera controls.
Shared Docking Station With Other ThinkPad Series
Select T Series laptops share common docking stations with select models with the ThinkPad X, L, and W Series, which can save on equipment costs and make managing parts numbers easy. Plus, all Series 3 docks use the same docking connector and provide ports aplenty. The ThinkPad T431s includes an adaptor for simple, left-corner alignment. See ThinkPad Port Replicator Series 3, ThinkPad Mini Dock, and ThinkPad Mini Dock Plus Series 3.
Lenovo Mobile Access
This pay-as-you-go wireless WAN (WWAN) mobile broadband service enables online access anywhere, anytime, with flexible pricing and no contract needed. Perfect for travelers.
Lenovo Solution Center
A simplified dashboard that reflects total system health. This hardware diagnostic tool allows quick and convenient access to frequently-used system management tools, including backup and restore, antivirus and firewall settings, system/software updates, internet connections, and service and support.
