Review Lenovo ThinkPad L440 Notebook

Lars Schmidt (translated by Liala Stieglitz), 12/20/2013

It's a ThinkPad – will it do the thinking for you? At first glance, Lenovo's new L440 from the ThinkPad line looks well-built and seems rigid as expected. Find out in our test report whether the laptop can live up to this first impression, and whether it can compete on the market in terms of performance.

For the original German review, see here.

There is not much to be said about Lenovo's ThinkPad series (formerly made by IBM). These devices have been available for over two decades, and can probably be counted to the founding devices of compact business laptops. After all, we do have a few ThinkPad reviews in our repertory.

Our current Lenovo ThinkPad L440 (model 20AS-001CMZ) features the new Intel Core i5-4330M CPU alongside the integrated HD Graphics 4600 GPU, 4 GB of working memory, a 500 GB hard drive, and a 14-inch HD screen.

Interestingly, the L440 models presently listed in German online shops are all based on Intel's i5-4200M CPU. Its performance reserves are a bit lower, as can be read in the following sections.

Potential contenders are found among the entry-level business devices, for example from Dell, Fujitsu, and HP. Notebookcheck has previously reviewed Fujitsu's LifeBook E743 and Dell's Latitude 3440. Both are offered in various configurations, and are roughly within the same price range. HP positions its ProBook 640 G1 here, which we have not yet tested.

Case

Lenovo ThinkPad L440 - gap between the lid and base unit

The casing of Lenovo's ThinkPad L440 is made completely of matte-black plastic with a very finely roughened surface. This unfortunately also makes it look like "just" a solid work device, and does not convey the slightest hint of elegant design. The only eye-catcher is the ThinkPad logo on the lid's back. The i's dot lights up when the laptop is on, and blinks in energy-saving mode. Basically, the laptop's entire appearance is simply typical ThinkPad.

Stable hinges keep the display in position, and the latter can be opened generously up to an angle of 180° to the back. Our review sample's lid does not close quite flush with the base unit though. The screenshots clearly show how the gap gets bigger toward the front. This will likely not be disturbing because the plastic is pliable enough to not break. However, this should be mentioned considering the device's price range. Except for this point, the other parts are well-manufactured.

Connectivity

The ThinkPad L440 has a VGA-out, which will certainly be useful for some projectors, and a mini-DisplayPort. An HDMI port is not installed. There is also only one powered USB 3.0 port, and 3 USB 2.0 ports. The other way around would likely be more appreciated nowadays. An SD card reader is also available for fans of digital photography. It is well-hidden on the front, lower right side. A combined 3.5 mm headphone-out and microphone-in jack is installed for audio peripherals. In addition to the integrated Wi-Fi module, a 1000 megabit/s (Gigabit Ethernet) BASE-T network socket (RJ45) is available. Besides that, there is also an ExpressCard and/or SmartCard slot in the laptop.

Communication

The state-of-the-art Advanced-N 6235 Wi-Fi module from Intel's Centrino line is used in the ThinkPad L440. It supports the Wi-Fi 802.11 a/b/g/n standard, and dual-streams (2x2). This enables transmission rates of up to 300 Mbps. Besides that, it supports dual-band, and can be used in both the 2.4 GHz and 5 GHz mode. That also contributes to speed, among other things, and can thus reduce possible data congestion. The 5 GHz band also has the advantage that it is not (yet) as busy, and thus contains fewer sources of interference.

The connection was tested using 2 routers; one was located in the laptop's direct vicinity (approx. 2 meters), and the other was two stories above the workplace (approx. signal strength: 50-60%). There were no problems with the Wi-Fi reception in either case.

The Ethernet adapter is also on a good level with 1000 megabit/s (Gigabit Ethernet). Intel's Centrino module also supports Bluetooth 4.0.

A light-sensitive HD webcam with a wide-angle range and Face-Tracking from Vimicro Corporation, as well as two microphones with noise cancellation provide the necessary communication tools for web conferences. The camera shoots fairly focused pictures in the 720p mode, but they are partly very noisy especially in somewhat darker ambient light. It is not intended for making HD videos, and its performance is fully sufficient for communication usage. Thus, the camera serves its purpose. Face-tracking works very well. An activity LED indicates whether the camera is on.

Accessories

Not many accessories are included for the ThinkPad L440. The review sample only included a quick-start poster, and a card of recommendation for Lenovo-branded laptop bags.

Operating System and Recovery

The ThinkPad L440 is delivered with Windows 7 (64-bit) installed. A Windows 7 DVD is not included; instead a partition dubbed Lenovo Recovery is on the internal hard drive. The system can be reset via the included Lenovo ThinkVantage Tools software. This tool also enables creating a backup of needed files on an external data carrier, which is certainly recommendable. After all, a hard drive could take damage.

Maintenance

The ThinkPad has a relatively large maintenance cover for accessing the inner components. Besides the four screws that have to be removed, there is also an additional fixture system comprised of plastic clips (for no evident reason). They make it difficult to open the cover without accidentally damaging them because they are virtually predestined to break here. In any case, the user should attempt this very carefully so to not break the plate or clips. Thus, it would be better to not open the laptop when it is not absolutely necessary.

Should this, however, become necessary, it would be advisable to download the corresponding Hardware Maintenance Manual (42.2 MB!) from Lenovo's website, where this procedure is illustrated. Unfortunately, the exact location of these clips is not depicted.

The user can access the hard drive, working memory, Wi-Fi module, and BIOS battery when the cover is removed. The latter is easy to replace because it is only inserted via a connector, and not soldered.

The ThinkPad L440 features two easy-to-access working memory banks, one of which is furnished with a 4 GB module. The hard drive can also be replaced easily (e.g. with an SSD). The size of the installed hard drive slot offers the usual space for 2.5-inch hard drives.

Warranty

A base warranty of 36 months is included on the laptop, and corresponds to the class standard. Warranty upgrades or extensions are optionally available. For example, Lenovo currently charges 81.60 Euros (~$111) for an upgrade to 48 months on-site service via the Internet.

Security

As to security, Lenovo's ThinkPad has quite a bit to offer. Besides the fingerprint scanner common in this category, there are other security and management features, such as Intel's vPro, Computrace, hard drive encryption, BIOS lock, Trusted Platform Module (TPM), and ThinkVantage Password Manager software. The Active Protection System (APS) for conventional hard drives should also be mentioned. This security mechanism detects strong shocks to the system (or even drops), and parks the hard drive's read head to protect stored data. According to Lenovo's website, special tests similar to military standards were also performed with the laptop.

Input Devices

Keyboard

A standard-sized, spill-resistant keyboard is used in the laptop (our review sample had a QWERTZ layout). It features a fairly long drop with a well-defined pressure point, and quiet stroke. The keys' surface is sleek (not roughened), and they are slightly concave. Typing quickly on the keyboard is very pleasant, and even some desktop keyboards cannot compete with it - definitely a bonus point.

Touchpad

As good as the keyboard is the 100 x 75 millimeter touchpad gives reason for complaint. Here, one of the biggest modifications of recent years is found in form of the 5-key ClickPad. For example, the two dedicated touchpad, or mouse buttons have now been omitted. Lenovo has integrated them into the touchpad's surface so that the entire pad is now a button with an unusually high drop. Consequently, it feels a bit like a wobbly platform. Unfortunately, precise cursor control is only possible to an extent because the finger often "slips" away. Users who have only used a conventional touchpad until now will certainly find it very strange, and will need a bit of getting used to. However, this is not devastating for those who work with more sophisticated programs because they will likely connect an external mouse, and the red TrackPoint in the keyboard's center is another alternative for controlling the cursor.

Display

A 14-inch HD anti-glare screen with a native resolution of 1366x768 pixels (16:9 format) is installed in the ThinkPad L440. The screen's average brightness of 204.4 cd/m² is within an acceptable range. We also found a reference to an optional HD+ screen with 1600x900 pixels in various spec sheets from Lenovo.

Fujitsu's LifeBook E743 that we tested also relies on an HD+ screen, but one that is much brighter. Our test sample of Dell's Latitude 3440 also features a bright HD+ screen. We would recommend the HD+ alternative of the L440 when importance is placed on a good overview, and working with multiple windows or larger spreadsheets.

The contrast ratio of 655:1, and a black level of 0.323 cd/m² places the ThinkPad within a good field. Dell's Latitude E3440 accomplishes marginally lower results with rates of 438:1 and 0.78 cd/m². Fujitsu's E743 is on par with that.

Unfortunately, the DeltaE 2000 shifts of many colors reached a rate of over 10. Only black and blue accomplished the target range of DeltaE < 5. The screen in the ThinkPad L440 cannot fully reproduce either the sRGB or AdobeRGB color space, which should not discourage average users.

The ThinkPad L440's viewing angle stability is not quite as good. The displayed image quickly loses brightness and contrast, which also unfortunately limits outdoor use to an extent. The expectations placed on the quality of a screen from this price range have thus not been satisfactorily fulfilled.

The native resolution of 1366x768 pixels could also be a bit higher for a laptop from the business category. Like the contenders, the ThinkPad is not necessarily meant for photographers or graphic designers because the ascertained rates do not meet the professional demands in these fields. However, we did not determine outstanding color deviations using only our eyes.

Performance

Lenovo clearly focuses on processor power and security in its ThinkPad L440. Intricate 3D games, however, do not quite belong to the laptop's intended application field. Since only one of the two working memory banks in the ThinkPad L440 is filled, the working memory only operates in single-channel mode. A considerably higher performance could be achieved by installing a second RAM module with the same memory capacity because the dual-channel mode would lead to a higher data transfer rate between processor and memory. Installing a solid state drive (SSD) would naturally also lead to a performance boost. All in all, the ThinkPad L440 is a reliable companion in the work world owing to its strong battery, many security features, and rigid casing, and has enough performance reserves for many tasks.

System information: Lenovo Thinkpad L440

Processor

A special highlight of our Lenovo review sample is certainly the swift Intel Core i5-4330M CPU that is based on Intel's new Haswell architecture, and built in 22 nanometers (TDP: 37 watts). This mobile dual-core CPU has a base clock of 2.8 GHz, but can achieve speeds of up to 3.5 GHz via Intel's Turbo Boost technology. The processor also supports Hyper-Threading, which enables both cores to process 4 threads simultaneously. The integrated Intel HD Graphics 4600 GPU takes care of graphics work.

Lenovo also offers the ThinkPad L400 with other processors. At the time of writing the preconfigured models available in Germany were all listed with an i5-4200M that clocks a bit slower (2.5 to 3.1 GHz), as the test configuration's counterpart.

The chip achieved an excellent score in the Cinebench R11.5 single-CPU test, and places itself approximately on the same level as the current i7-4700MQ quad-core CPU. The i5-4200M lagged behind by about 10% in the same test. The advantage over the i5-4200U ULV chip that is currently often used is very clear with approximately 25% (Latitude 3440).

The score in the Cinebench multi-core test is just as impressive. The chip advances to the top ranks of mobile dual-core processors. The 4200M again lags behind by approximately 10%, and the i5-4200U falls behind by about 30%.

System Performance

The swift CPU easily manages all routine tasks, and still has plenty of reserves. Consequently, nothing starts to lag so quickly, and working with office & business software is smooth. The booting time of Windows 7 is fairly normal with just under 30 seconds.

We have to mention that some laptops featuring the same GPU achieve much higher scores in the PCMark benchmarks. This could partly be because the working memory only operates in single-channel mode, as said above, and the graphics card takes its part from the RAM in shared-memory mode. The PCMark Vantage score (6949 points), as well as the PCMark 8 (2287 points) score could improve significantly after eliminating this system bottleneck.

Storage Device

Lenovo installs a conventional SATA hard drive from Toshiba (model: MQ01ACF050) in the ThinkPad L440. It has a capacity of 500 GB, and spins with 7200 revolutions per minute. CrystalDiskMark ascertained a read speed of 121.5 MB/s. HD Tune recorded an average transfer rate of 105.8 MB/s. Those are throughout good rates, but a solid state drive (SSD) would be more wanted in an office device. Of course, no storage system can provide full protection against data loss, regardless of whether the data is stored on a conventional hard drive or SSD. However, it would be an additional security aspect besides the performance gain because SSDs do not have any mechanical moving parts that can easily take damage. That would make the system even more insensitive to external shocks.

Graphics Card

Lenovo does not use a dedicated graphics solution, and completely relies on the Intel HD Graphics 4600 graphics core integrated into the i5-4330M. It supports DirectX 11.1, OpenGL 4.0, OpenCL 1.2, and DirectCompute 5.0. The GPU features an improved decoder for 4K videos, and a revised QuickSync encoder is also on-board. Its default clock is 400 MHz, which can be increased up to 1.25 GHz dynamically. The graphics/3D performance of the integrated GPU is throughout adequate for multimedia applications. In terms of performance, the HD 4600 is approximately on par with AMD's HD 7660G Trinity GPU, and thus slightly lower than a dedicated GeForce GT 630M.

Compared with Intel's HD Graphics 4400 in Dell's Latitude 3440, the HD Graphics 4600 in the ThinkPad has a higher clock, and theoretically provides more power.

Super Streetfighter IV Arcade Edition

The ThinkPad L440 certainly cannot be considered a gaming laptop. Although the integrated GPU is quite fast, it will have difficulties with current games like Assassin's Creed IV: Black Flag, Call of Duty: Ghosts, or Battlefield 4 due to insufficient performance reserves. We nevertheless tried a few titles. One game that still ran smoothly using high graphics settings was Super Streetfighter IV Arcade Edition. The graphics settings for the other two tested games should be left on low so that reasonable frame rates are achieved. Details can be found in the chart below. More games can be found here.

Emissions

System Noise

We ascertained a fairly high noise development ranging from 33.1 dB(A) to 33.3 dB(A) in idle. That is not inevitably distracting because the level is virtually undeviating - it is just very audible. Noise peaks of 33.6 dB(A), which were produced by the hard drive's quiet clicking even in read access, were noticed more adversely. This could be eliminated by replacing the hard drive with a solid state drive (SSD).

This looks completely different during load. The ThinkPad L440 made a very good impression with rates of 34.8 dB(A) in medium load, and 35.7 dB(A) in full load.

Temperature

The ThinkPad's temperatures remain on a moderate level with rates between 27 °C and 33.7 °C on the upper side and a maximum of 36.3 °C on the underside. Thus, the laptop can be used on the thighs without hesitation.

This is different when the system is maxed out. The ThinkPad's rates climb up to 47 °C, which is quite a heat development but still uncritical.

Speakers

The Dolby Advanced Audio stereo speakers in the ThinkPad L440 are in the base unit's rear area on the device's upper side. They produce a very treble-heavy sound quality, as expected in view of the casing's small size. There is no real bass, but speech is well-intelligible. Of course, the user should not expect Hi-Fi quality. It is possible to connect external speakers or headphones for movies or presentations via the 3.5 mm jack, USB or Bluetooth for a better sound experience.

Energy Management

Power Consumption

The measured power consumption of the ThinkPad L440 ranged from 8.6 watts in idle (min. brightness, energy-saving profile, wireless communication modules off) up to a high 53.4 watts during full load (max. brightness, high-performance profile, wireless communication modules on, stress test via Prime95 and Furmark). The laptop still consumed 48.1 watts during medium load in 3DMark06. However, the 65 watt power supply is designed sufficiently for this.

Dell's Latitude 3440 is within a similar range with a minimum of 7.5 to 8.3 watts up to 49 watts during full load.

Battery Runtime

"Enjoy all-day computing with up to 12 hours unplugged on the standard 6-cell 56 Wh battery—whether you're working on-the-go or simply enjoying downtime..." is found written on Lenovo's website. This sounds very optimistic at first. A remarkable runtime of 10 hours and 55 minutes in Battery Eater's Reader's test surprised us even more. Although it is performed in idle mode using minimum brightness and Window's energy-saving profile, some current ultrabooks cannot quite keep up with that. This impressive runtime is, however, only a theoretical rate to test the battery's possibilities, and only has little significance for real-life work habits.

Of course, the battery runtime decreases as soon as the wireless communication modules were enabled, and we browsed on the Internet with the screen's brightness set to medium (approx. 150 cd/m²). However, the ThinkPad still lasted for almost 8 hours in this practical Wi-Fi test (7 hours 51 minutes). The ThinkPad first had to be switched to AC-mode after almost 2 hours (1 hour 54 minutes) even during maximum load using Battery Eater's Classic test (max. brightness, Window's high-performance profile, wireless communication modules on).

Verdict

Lenovo ThinkPad L440
Lenovo ThinkPad L440

The ThinkPad L440 provides very good CPU performance. The laptop's power consumption is low when it is not running at its performance limits, and thus achieves unexpectedly long battery runtimes, even without a ULV CPU.

We found it a bit annoying that the window for changing the screen's brightness occasionally popped up on its own. It is normally opened via the FN key. The touchpad's extreme sensitivity can also be annoying sometimes. The slightest touch while entering text can occasionally lead to unwanted results. For example, while we were entering a name to save a file during the test it often happened that the touchpad detected a click, and the file was saved under a wrong name. The user should be particularly careful here. ThinkPad experts will, however, use the well-known TrackPoint to begin with.

As to the casing, the L440 cannot quite compete with the models from the T-series, but is still on a good level. We particularly hoped for improvement in the screen. Buyers should opt for the optional HD screen that provides more overview and image sharpness.

Shortcut

What we like

The really good keyboard.

What we'd like to see

A somewhat better screen and the "old" touchpad from the previous models.

What surprises us

The laptop's endurance.

The competition

Lenovo's business laptop has to compete with many high-profile contenders particularly in terms of configuration. Depending on the application scenario, the ThinkPad naturally has its tried advantages, and it can presently score with the available CPU power in any case. The comparison models used in this review were: Toshiba Tecra R950-192, and Dell Latitude E6530.
