Review Lenovo ThinkPad X240 Ultrabook


Pioneer. The 12.5-inch ThinkPad of the X series has been completely revamped - while still staying true to the core strengths of its well-made predecessors. Mobility, flexibility, ergonomics and great build quality are characteristics which are not...

Keyboard; Display; Battery life; Power Bridge system; Noise emissions; Mobility

Connectivity; Localized build quality issues; Clickpad buttons; Throttling issues while under full load

That Intel's Haswell CPUs have such an impact on power consumption, making it possible to increase battery life while simultaneously decreasing the battery capacity.

Lenovo ThinkPad X240 review: A no-nonsense business laptop


Intel's Haswell CPU comes to the ThinkPad X-series.

Durable glass-fiber chassis ; Hot-swappable battery ; All the I/O ports you could ask for

Disappointing 1366 by 768 display ; Keyboard not up to ThinkPad standard ; Weak speakers

The solidly designed Lenovo X240 Thinkpad features fourth-generation Intel Core processors and hot-swappable batteries. But its display resolution of just 1366 by 768 is disappointing at this price point.

Lenovo ThinkPad X240


The Lenovo ThinkPad X240 is a powerful business laptop sporting a Core i5 Haswell CPU, a 12.5-inch IPS touch-screen display, and a whopping 15 hours of battery life.

Solid performance. Incredible battery life. Responsive touch screen. Sturdy design.

Low-resolution display. Pricey.

Whether you're a long-time ThinkPad enthusiast or a newbie, the X240 is an excellent example of why the brand has been so successful for so many years. Solid performance and a durable design make this ultrabook an ideal travel companion, and its...

Lenovo ThinkPad X240 review: All-round excellence


The ThinkPad X240 offers plentiful configuration options, tried-and-trusted design, solid build quality and a twin battery configuration that delivers long battery life. Overall, this is an excellent business ultrabook.

Tough build ; Plenty of configuration options ; Solid performance ; Integrated mobile broadband option ; Twin battery configuration delivers long battery life

Relatively heavy ; Higher-end configurations are expensive

The Lenovo ThinkPad X240 impresses on every front. The configuration options are plentiful with touchscreen, HDD/SSD, mobile broadband and different Windows versions all in the mix. We like the legacy VGA port, the usable keyboard, the...

Lenovo ThinkPad X240 – Reviews, Specs and Features


My personal experience with the Lenovo ThinkPad X240 is somewhat limited, as I haven't got it for a proper review. However, even in the few hours I got to play with it, I was impressed with the solid construction and the light weight, compared to my...

Lenovo ThinkPad X240 Ultrabook Review: A Philosophical Shift


Alongside our T440s review unit was something slightly smaller and dear to our hearts: the latest entry in the ThinkPad X series of notebooks. Seeing as this very review is being typed on a Lenovo X220, our interest was piqued by the latest refinements...

Ridiculously long battery life with hot-swappable battery, Excellent keyboard and touch screen, Solid all-around performance, Laundry list of extra features

Better configurations grow pricey, No HDMI and only two USB ports, Touch pad can miss clicks, Only one memory slot (8GB max), Low-res Webcam

The ThinkPad X240 isn't perfect, but the flaws we found are minor in the scheme of things. If you can work it into your budget, you'll be rewarded with plenty of performance, stellar battery life, a business-rugged design, and a top-of-the-line screen...

Lenovo ThinkPad X240 Ultrabook


Lenovo's ThinkPad X240 is a very different beast compared to the X230, but still one of the best small laptops on the market

Slim and solid design ; Very good keyboard ; Battery life ; In-built features

Keyboard not backlit by default ; Some keys are smaller compared to the previous model ; Virtual TrackPoint buttons are not comfortable

Lenovo's ThinkPad X240 is a 12.5in Ultrabook that's small and sturdy, yet comfortable to use. Most importantly, it's a very reliable machine, and it has a dual battery system that allows for a very long run time away from an outlet. It's one of the...

Lenovo ThinkPad X240 review


This 12.5-inch ultrabook packs everything but punch

Tons of ports for size ; Hot swappable batteries ; Great fingerprint reader

Dense for small size ; Easily out specced ; Squishy keyboard ; Poor value

Lenovo crammed a ton of hardware into this business ultrabook, but the ThinkPad X240 comes up short on power versus price.
