Lenovo ThinkPad T431s review Gray flannel suit with a modern cut
Lenovos ThinkPad T431s is a comfortable mix of old and new. Like past T-series laptops, it is first and foremost built for business and the wear and tear of daily use -- on and away from a desk. But, thanks to some careful tweaking, its not stodgy and stuck in the past.
The processor and integrated graphics are a generation behind, so if having the latest components is necessary for your work this model wouldnt be the choice. That goes for discrete graphics, too; its integrated or nothing for the T431s.
The value of the T431s comes from its updated design, its durable construction, and its security features. Its a laptop that will make most IT departments happy that you picked it, but its got enough of a consumer notebook look and feel that youll want to use it in your off time.
True to its roots, the T431s is a basic black notebook. If youre looking for a "look at me" laptop, youre reading the wrong review. That doesnt mean its boring or generic, just that its simple and straightforward.
The lid is made from carbon fiber while the bottom is magnesium alloy, and inside is a roll cage protecting its components. And although the slim, lightweight body doesnt look particularly tough (it measures 13 inches wide by 8.9 inches deep by 0.8 inch thick and weighs 3.6 pounds), the T431s is capable of passing Mil-STD-810 testing for extreme temperature, pressure, dust, humidity, and vibration, and the keyboard is spill resistant. If you want a thin-and-light laptop that wont disintegrate when used outside of an office, airport lounge, or coffee shop, this should be on your short list.
Along with strong construction, you get security features that include Intel vPro technology with Anti-Theft protection (AT-p), data encryption via an optional Trusted Platform Module chip, and integrated fingerprint and Smart Card readers.

Whats new on the keyboard is that volume and mic controls are now integrated into the function keys instead of having dedicated controls for those features. Lenovo also added Windows 8-specific function keys for opening panes for settings, search, viewing open apps, and viewing all apps. Function keys can be easily locked and unlocked, too, for those who want traditional function keys. Also, pressing the Fn and spacebar key will turn on and off the keyboards backlight, if you pay for that feature; my review laptop didnt have a backlight.
The rest of the touch-pad experience is good, though clicking did feel a bit mushy on my review system. Also, if youre the type to drag your palms when typing (I am), youll want to crank up the PalmCheck sensitivity. Even then you might experience the occasional cursor jump.
From head-on, the screen looks very good with nice color performance. Its also a matte screen, which, combined with its 250-nit brightness, is good enough to fight off the stray reflections you get from glossy screens. However, if you frequently have people huddled around your screen, they might find it very difficult to see what youre seeing. The poor viewing angles are particularly noticeable when watching movies or viewing graphics or photos; text is less of an issue.
Lastly, though I doubt its a major consideration when purchasing a business laptop, the T431s speakers are really pretty good or, at least, better than expected. For movies and music theyre more than sufficient; voices sounded clear and full.
Connections, performance, and battery
Much like the updated touch pad, the T431s data and networking features are a mix of legacy options business users need and modern connections to keep it current.
For example, on the left side you get an analog VGA output, but on the right you have a digital Mini DisplayPort.
