Thinkpad T440s, Lenovo’s Best Business Machine!

lenovo t440sLenovo ThinkPad T series have always been a good line of business laptops. Regardless of their look, they have been well known for their great performance, extended battery life, and superior usability. Undoubtedly, the T440s is no exception. Moreover, it probably is one of the best and most successful laptops of the series. The 14-inch ThinkPad T440s held the legacy as expected with strong 4th Gen Intel Core i7-4600U processor, incredible IPS screen with full HD 1080p resolution, 8GB of ram, 256GB SSD, a high-quality backlit keyboard, a durable battery and all those in a well-made 3.6 pound structure.

However, with so many versions available, and a starting price of $1349, neither this business powerhouse is cheap nor it is easy for buyers to figure out which model is best suited to their individual needs. So, before coming to a conclusion, take a look at our review and see for yourselves if the ThinkPad T440s is worth the investment.

lenovo t440s 2Build and Design

The Lenovo T440s carries the same design style as other ThinkPads. There are no fancy designs on the lid to make the laptop look skinny or light. It’s a simple, black rectangular smooth designed case made of thick black plastic. However, the outer body of the laptop features carbon fiber coated matte black lid and magnesium chassis. There is a ThinkPad logo on the lid with a red light on the letter “i” that indicates the conditions of the system when lid is closed. Like any other T series ThinkPad, the T440s is built to take some pounding. There is an integrated roll cage inside the case which helps the laptop survive falls, while solid hinges at the joint allow the screen to bend back 180 degrees.

lenovo t440s lidLenovo says that the T440s has passed several military standards, or MIL-SPEC tests, including those for humidity, dust, extreme temperatures and vibrations. But considering the measurement and weight, this ThinkPad isn’t the most portable Ultrabook on the market nor the best looking. However, with top-notch durability and the addition of what is inside, the added weight surely is well worth.


The ThinkPad series is famous for their high-quality keyboards and this one is no different. It offers the familiar Chiclet island-style spill-resistant keyboard as expected. The keys are rounded and have a glossy finish. Lenovo used an inward curve design for the keys that helps provide extra grip. Spacing between the keys is good which gives a pleasing feel in each and every stroke. With each key instantly snapping back into place after being struck, the tactile feedback of the keyboard is really strong.

Like other ThinkPads, the T440s offers both touchpad and TrackPoint. As you can see in the picture, there is a red TrackPoint stick located directly above the “B” key. To be honest, this TrackPoint offers more precise navigation around the desktop than any touchpad. This stick also allows typists to move the pointer without moving their hands off of the keyboard.


On the other hand, the buttonless touchpad of the T440s is not really that bad. The large, 3.9 x 2.75 inch touchpad placed directly below the spacebar. The surface of the touchpad is rubbery enough to move around without slipping fingers. Multi touch gestures, such as pinch-to-zoom, rotate, swipe in from right for charms, swipe in from left to switch apps and four-finger swipe to minimize all apps, also works smoothly.lenovo t440s touchpadsOverall the performance of the touchpad is really accurate and it can read all kind of motions and gestures without having any noticeable lag. However, right, left and scroll buttons are on the top of the touchpad. Pushing down on the top of the pad requires considerably more force than the touching the dedicated buttons which is very uncomfortable and unusual.


As an ultraportable laptop, it should come as little surprise that the ThinkPad T440s offers rich connectivity. The chassis is 0.8 inches thick, which provides enough room for several important ports that many other Ultrabooks failed to equip.

Though most users should be all set with the Display port and VGA connector, some of you might feel the lack of an HDMI connector. But in that case, you can always use a converter.

Lenovo T440s offers a matte FHD display with a resolution of 1920×1080 pixels and IPS technology. The screen is rich and sharp. Because of the IPS panel, the display images are always clearly legible, even from extremely wide viewing angles. As the display has a matte surface, users don’t have to suffer reflections from outside light sources which makes the laptop perfect for outdoor use.

Though the panel is kind of glossy, it doesn’t reflect back much light as well. Along with everything, 1080p resolution provides great desktop space.


Though it is enough for personal use and watching movies, the sound system of T440s is not something to brag about. There is a pair of speakers on the bottom of the chassis. Though they are on the bottom, the sound they provide is quite loud and can fill a small room. Additionally, the included Dolby v4 audio software makes the audio quality much more comfortable. Without the Dolby v4 feature, the outputs become lifeless and barely enjoyable.


lenovo t440s processorWith 2.1 GHz fourth generation Intel Core i7 4600U processor, 8GB of RAM and 256GB SSD, the ThinkPad T440s provides very strong performance, which is good enough for demanding productivity work and small gaming. With its speedy 256GB SSD, the T440s booted Windows 8 in just 13 seconds.

Heat and Noise

The Lenovo T440s has a vent on the left side of the chassis which does not curve down towards the bottom portion of the chassis. So, any heat flowing from the device will be directed away from the user.

Usually, the laptop stays cool and quiet under small to medium pressure. After watching full HD videos for around half an hour, the device remained relatively silent while the touchpad measured a cool 27 degrees, the keyboard 29 degrees and the underside 31 degrees Celsius. However, under heavy pressure the fan produces an audible noise. Luckily under normal circumstances, you probably will never face the noisy problem.


ThinkPad T440s comes with a choice of two batteries, a 3-cell, 23.2 watt hour unit and a 6-cell, 72 watt hour high capacity battery that costs just $5 extra. In addition to these removable batteries, the T440s has a non-removable 3-cell internal battery, so you can change batteries without shutting the system down. With the 3-cell 23.2Whr battery, the T440s lasted roughly 8 hours while we watched movies, played music and browsed the internet over Wi-Fi.

Wrap Up

For about $1350, Lenovo is offering a business laptop that satisfies almost every possible desire. To be honest, the only point of criticism we have is the lack of touchscreen.

With the fourth generation’s Intel Core processor, solid state drive, amazing battery life, top class keyboard and a full HD IPS screen, the ThinkPad T440s is one of the best business laptop on the market, if not the best. It is the best business machine you can possibly get, if the price tag is not a problem for you.
