Military-specification testing validates the ruggedness, durability, and quality of this laptop by testing against 11 parameters: high pressure, humidity, vibration, high temperature, temperature shock, low pressure (15,000 ft), low temperature, solar radiation, fungus, salt fog, and dust.

Ghost Touch, Running Touch, No-Touch, and Inverted Touch are not screen related issues. Kindly check your digitizer board and cable since they are the most likely cause of any touch issue; please do not open a return claiming the touch did not work. If the machine has a weakened or fragile digitizer board, the replacement unit or assembly will not have proper touch or in some cases it may not have touch at all.

The return of the old master. What can be improved in an almost perfect notebook? Lenovo might have thought that it is better not to change too much and launched an only slightly revised edition of the T440s with the ThinkPad T450s. At least, the manufacturer (partly) answered the complaints about the predecessor"s unusual five-button ClickPad.

The T series is Lenovo"s flagship of the ThinkPad family and has been a byword for premium business notebooks for years. Build quality, reliability, and security are given highest priority. The manufacturer does not confidently tout these models as premium products without reason.

In this review, we will focus on the especially lightweight and mobile ThinkPad T450s, the successor of the T440s, which was already presented in September 2013. We had to wait relatively long since Intel"s fifth-generation Core called "Broadwell" was delayed and first broadly available at the beginning of this year. As usual Lenovo only incorporates frugal 15-Watt CPUs of the Core i5 and Core i7 class. In addition, the models feature 4 to 12 GB RAM and an HDD or an SSD as storage device. In addition, Lenovo offers multiple options for display, radio modules, and battery capacity. The following list gives a brief overview over the models available in Germany.

Our test model comes with a Core i7-5600U, 12 GB RAM, a 360 GB SSD and an IPS display with Full HD resolution for roughly 1400 Euros (~$1567). But, this price is only valid within the Lenovo Campus program for e.g. students and teachers. The model lacks OS and LTE module, but you can save several hundred Euros compared to a regular model with comparable equipment. The price might appear too steep to you, but direct competitors like the Dell Latitude 14 E7450 or the HP EliteBook 840 G1 (whose 840 G2 successor will be available soon) are priced similarly.

Lenovo has already only carefully changed the design and build of the T400 series in the past. It even appears that they did not change anything in this generation: Weight and size are almost the same as the T440s" and it does not look different, either. At a first glance, the functional designmight have the dubious charm of plain plastic, but the case is based on a high-end light metal skeleton made from aluminum and magnesium. The lid was even reinforced by carbon fibers.

As a result, the T450s belongs to the stablest devices of its class. Localized pressure and twisting attempts do not have an effect on base unit and display, although we would not have expected this from the delicate ultrabook at first. In addition, the ThinkPad should be able to withstand other environmental hazards like temperature and air pressure changes, vibrations, moisture, or dust, which has been tested to military standards according to Lenovo. However, many competitors also lure buyers with this.

We are especially delighted by the functionality of the case, which you will only gradually discover during everyday usage. For example, the smooth surface is very resistant against fingerprints and scratches. In contrast to soft touch surfaces, dust can be easily removed. Extremely flexible metal hinges allow opening the display by above 180 degrees. The manufacturer optimized the resistance in such a way that the lid neither wobbles nor the base unit lifts up when the laptop is opened. We did not find any workmanship flaws, at least not in our test model.

Lenovo belongs to the last manufacturers keeping the outdated VGA-out. So, users do not need to take additional adapters with them in case an older projector might still require this interface. However, you"re better off connecting modern flat screens via Mini DisplayPort, which is capable of 60 Hz at 3840x2160 pixels. Previously, this only worked with computers with dedicated Nvidia GPUs, while the refresh rate had to be decreased to 30 Hz for all others. It"s a pity that the ThinkPad does not feature a second digital video-out like HDMI.

While only a few modules include an integrated UMTS/LTE module, all T450s models supportBluetooth 4.0and WLAN. The Wireless AC 7265 from Intel masters the Wi-Fi standards802.11 a/b/g/n/acand is capable of dual stream (2x2) and dual-band. In our test, we recorded data rates of just under28 MB/s (802.11 ac, 5 GHz) and a good 10 MB/s (802.11 n, 2.4 GHz) in short distances. While this is not a bad result, we already recorded significantly higher values with the same module and our TP-Link Archer C7 router in the past. However, range and connection stability are above average, which is often more important in everyday life.

In contrast to smartphones, which make conventional compact cameras more and more obsolete, the webcam quality of notebooks has remained low for years. Unfortunately, our ThinkPad is not an exception. The sensor can only record a few details with its poor resolution of 0.9 MP. In addition, the image is visibly noisy, especially in low light scenarios. In contrast, its array microphone was considered more important and convinces with clear voice quality.

If a company"s laptop is stolen, it is not the loss of the device itself, but the sensitive data that causes the biggest damage. Therefore, the T450s not only comes with physical protection mechanisms like a Kensington lock, but it also delivers features like a hard drive with hardware encryption. Passwords for BIOS and system start as well as a Smartcard reader and a fingerprint reader should bring extra security to the computer featuring TPM (TCG 1.2). In case the device is lost anyway, you can remotely locate it or format its drive with Anti-Theft/Computrace (additional, fee-based contract required).

If you buy a ThinkPad model without operating system, the manufacturer does not include any driver CDs. However, drivers for Windows 7 Professional (or Windows 8.1) can be downloaded from Lenovo"s website. Apart from the laptop, we only found a few leaflets and the small 65-Watt power adapter in the box. So, the scope of delivery is meager, yet sufficient.

Even without reading the included hardware maintenance manuals, many service tasks can be quickly and easily performed. First of all, remove a total of ten Phillips screws from the underside. Afterwards, take off the underside carefully and you will get to the RAM (one slot, occupied), drive (2.5-inches, height of 7 mm), Wi-Fi module, internal battery as well as the only fan of the device. There is a free M.2 slot for retrofitting a WWAN adapter or connecting a second SSD.

Typical for a business device, the T450s includes a three-year manufacturer"s warranty, which even includes on-site service in Germany and Austria. Once you entered the serial number, you can check the current warranty status or buy an upgrade for a fee. The prices appear to be reasonable in view of the laptop"s price. An extension of one year is available for 83 Euros (~$92). For a 5-year warranty you have to pay at least 168 Euros (~$188).

The touchpad has a size of 5.6 x 10 cm and delivers sufficient space for various multi-touch gestures with up to four fingers. However, precision and responsiveness are only completely convincing with dry fingers. It is much more difficult for sweaty fingers to glide over the very smooth surface. It is impressive that all features of the pad, from sensitivity of the palm rest sensor to the required pressure for inputs, can be configured in detail. Unfortunately, Lenovo still uses a so-called ClickPad with integrated mouse buttons, which brings a number of disadvantages. For example, the pad sometimes does not react immediately to the first click and the finger placed for clicking might accidentally trigger a multi-touch command.

Fortunately, there is a workaround for this problem: There are the easy to operate buttons of the TrackPoint above the touchpad surface, which can also be used with the touchpad. Once you got used to this solution, you can work quickly and reliably with the ThinkPad again. As an alternative, you can also completely move to the precise TrackPoint and completely ignore the touchpad.

Depending on the model, the 14-inch display of the T450s either has a resolution of 1600x900 or 1920x1080 pixels, which means a pixel density of 131 or 157 ppi, respectively. Because of the extra screen real estate alone, we would recommend the Full HD model reviewed here, which also boasts of other advantages: According to the data sheet, the more expensive display is brighter (300 vs. 250 cd/m²) and has a higher contrast (700:1 vs. 400:1). In addition, the IPS panel (the WXGA++ model is based on TN technology) promises wider viewing angles. A touchscreen version of the same Full HD display is also offered, but it is over 2 mm thicker, 200 grams heavier and slightly darker (264 cd/m² according to the manufacturer).

We measured 268 cd/m², which is slightly lower than the maximum brightness listed by Lenovo. However, this should not pose a big problem, since more than 250 cd/m² is hardly needed indoors and the competition also does not perform better. A uniform brightness distribution without disturbing bleeding is much more important, and at least subjectively we can say that the ThinkPad delivers such. The slight clouding on the adjacent picture is virtually invisible to the naked eye.

As already mentioned above, the display made by LG uses the contrast-rich IPS technology. Black areas do not even appear grayish or pale at maximum brightness, which gives rich pictures. The quality of the displays in the Latitude 14 E7450 or the Toshiba Tecra Z40t is comparable, but we only reviewed a TN model of the EliteBook 840 G1 (a Full HD IPS display is optionally available) so far.

Colors (DeltaE: 4.35) and gray levels (DeltaE: 3.7) do not give much reason for complaint in factory state. Our usual calibration especially improves the RGB balance and brings the color temperatures closer to the desired 6500 K, but also the DeltaE deviation decreases even further. However, the representation of a few yellow and orange colors remains problematic. Because of the limited color coverage (54.7% AdobeRGB, 84% sRGB - (Correction 20.5.2015 due to a wrong sRGB-reference-profile)) an external display is required for professional graphics design and picture editing, anyway.

In outdoor use, the bright, anti-glare display performs quite well and you can read from the screen easily in most scenarios. But, the T450s is not bright enough for use in direct sunlight, which would require a brightness level far higher than 300 cd/m². Those frequently working outdoors should also avoid the darker WXGA++ panel and the not completely matte touchscreen model.

Thanks to the IPS technology, the image also remains contrast-rich and unchanged from flat angles. This gets particularly handy when several users look at the screen simultaneously and you do not want to change the opening angle after each head movement. Color inversions and other image errors get immediately visible on many cheaper TN panels upon vertical movements.

The HD Graphics 5500 integrated into the processor features 24 Execution Units with a clock rate of 300 to 950 MHz. So, an especially big performance gain compared to the HD Graphics 4400 of the predecessor (20 EUs, 200 to 1100 MHz) is not to be expected. At least the GPU supports the current DirectX 11.2 standard now. Lenovo"s datasheets also mention an optional dedicated GeForce 940M. As the latter has not been officially introduced by Nvidia yet, we will have to wait for such configurations.

4 GB of the 12 GB DDR3L-1600 in our test device is soldered. The other 8 GB is in the single RAM slot of the notebook. This solution has two disadvantages: First of all, you cannot upgrade beyond the already available 12 GB RAM, and the memory controller only partly works in dual-channel mode, because of differing capacities. However, you should hardly notice a performance loss due to this in practice. A 360 GB SSD is available for applications and user data.

The Turbo clock rates of the Core i7-5600U mentioned by Intel are only maximum values. Other parameters like power consumption and core temperature determine whether and how long the CPU can actually clock that high in real applications. Broadwell chips profit from their advanced 14 nm lithography in this aspect, which allows higher frequency at the same power consumption than the previous 22 nm process.

Overall, the Core i7-5600U performs 10 to 15% betterthan the i7-4600U on average. The performance gain is usually lower in short single-thread benchmarks and higher with continuing full load on both cores. However, we would recommend the likewise new Core i5-5300U with same performance level as the old Core i7 to price-conscious customers. You"ll hardly notice the difference in practice, anyway.

Just like the smaller ThinkPad X250, the T450s also houses a 2.5-inch SSD with a capacity of 360 GB from Intel. It belongs to the SSD Pro 2500 series and is based on the no longer absolutely new Sandforce-Controller SF-2281 combined with MLC-NAND (20 nm) from SK Hynix.

If only performance is considered, the SSD is a mixed bag: While the sequential read (490 MB/s) and write rates (265 MB/s) are quite good, the drive"s 4K performance is weak. Several competitors from Samsung write small files partly five or six times faster than the Intel model, which only achieved 14.6 MB/s in this test.

Because of many requests, we also ran a short functionality test under Linux, in more detail under the current Ubuntu-Version 14.04.2 (64-bit). It was pretty easy to put the live system into operation: download the image and copy it on a USB stick, restart the notebook and select the correct boot medium with Enter and F12. Everything else works almost automatically, even most of the special keys (volume control, display brightness) and WLAN worked "out-of-the-box." Only the dedicated TrackPoint buttons caused problems, since they were not automatically detected by Ubuntu.

Despite of a performance gain of about 20 to 30% compared to the HD Graphics 4400 (Haswell), the new HD Graphics 5500 hardly achieves the level of dedicated low-end graphics cards. Even a GeForce GT 730M, which is optionally offered with the ThinkPad T440s, is about 30% faster in the synthetic 3DMark. The GeForce 940M promised for the T450s might even be twice as fast as the integrated GPU.

A ThinkPad is primarily used as a work tool. Therefore, we will only briefly cover games in this review. The HD Graphics 5500 is not suitable for modern, graphically demanding titles like Far Cry 4, anyway. But, it can at least run simple casual gameslike Dota 2 or Tomb Raider smoothly in low to medium settings. In order to better see where the T450s ranks in, we compared its performance to the Latitude E7450 (HD 5500, single-channel), EliteBook 840 G1 (HD 4400, dual-channel) and a cheap multimedia notebook from Asus (GeForce 820M) in the following diagram.

During longer periods with full load (yellow curve), the system noise increased to just above 34 dB(A), which is still quite quiet. Our measurements reveal medium to high frequency fan characteristicswith a peak around 2 kHz, which is slightly shifted upwards when the "Turbo Boost+" mode is activated in Lenovo"s energy manager (red curve). However, this option does not bring more performance or significantly lower hardware temperatures, but it only makes the system much louder with just above 40 dB(A).

Note: The noise levels in the adjacent frequency diagram cannot be compared with the values of our system noise measurements due to a different measurement setup.

(+) The average temperature for the upper side under maximal load is 30 °C / 86 F, compared to the average of 29.5 °C / 85 F for the devices in the class Office.

(+) The maximum temperature on the upper side is 35.1 °C / 95 F, compared to the average of 34.1 °C / 93 F, ranging from 21.2 to 62.5 °C for the class Office.

It is better not to expect too much from the stereo speakers of the T450s. They neither shine with high volume (max 77 dB(A) at 15 cm distance) nor with balanced sound. The pink-noise frequency characteristics recorded by us (light blue: medium volume, dark blue: maximum volume) show that already the volume of frequencies below 1 kHz is much lower. Frequencies lower than about 250 MHz are virtually non-existing. But the speakers also perform poorly in the high frequency range and remain far off the desired linear curve. Subjectively, we would call the soundflat and weak. The sound quality is sufficient for accompanying videos, but you would not like to listen to music with them.

Compared to the predecessor, the power consumption fell by about 0.5 Watt to 2.9 to 7.9 Watt while idle. However, it is difficult to tell whether this is only caused by the new CPU platform or also by other differing features. Overall, the T450s is slightly more frugal than the Latitude 14 E7450 (4.0 to 9.0 Watt) and the EliteBook 840 G1 (4.3 to 9.3 Watt).

Like the recently reviewed ThinkPad X250, Lenovo"s T series uses the so-called "Power Bridge" system, which consists of two separate batteries. One of them is inside the case and always has a capacity of 24 Wh, another 24 Wh battery (optionally 48 or 72 Wh) is connected to the rear of the case and can be replaced while the device is on. Thus, our T450s has a total capacity of 48 Wh available, which is slightly less than the Latitude (54 Wh) or the EliteBook (50 Wh).

In the Battery Eater Reader"s test (energy-saving mode, minimum brightness, radio modules off), the ThinkPad can hide this disadvantage quite well and achieves a similar battery life as its competitors with just under 13 hours.

Our WLAN and H.264 tests, run with a medium display brightness of roughly 150 cd/m², deliver quite realistic estimations of real-world use. With slightly above 5 hours, the T450s only performs mediocre here. This is especially true in comparison with the E7450, which is also based on Broadwell. Probably, the Latitude profits from a more efficient power management of its modern Windows 8.1 operating system.

In the full-load scenario, simulated by the Battery Eater Classic test (maximum performance profile, maximum brightness, radio modules on), the T450s runs out of steam after about 1:30 h. It takes about three hours until the batteries are fully charged again.

With the ThinkPad T450s, Lenovo launched a worthy successor of the successful T440s, which hardly offers real innovations, however. Whether case, keyboard, or connectivity - it apparently inherited many parts unchanged from its predecessor.

Even if this initially sounds like criticism, this is not necessarily what it is: Neither the stable and lightweight chassis nor the excellent ThinkPad keyboard required a revision. Just like we are used to, the T450s also performs flawlessly in other aspects, including many security features, the contrast-rich display, and the impressively low noise and temperature emissions. Nevertheless, the 14-incher does not lack performance and is even capable of demanding applications or multitasking.

The modified UltraNav unit consisting of a TrackPoint and a touchpad might still be controversial, but it is better than the previous solution. We still wish that the coming T460s will have only dedicated mouse buttons. In addition, Lenovo should incorporate two fully fledged RAM slots in a high-end product. A maximum of 12 GB could put many enthusiasts off.

Despite the mentioned points of critique, the T450s is a more than convincing bundle, which is finally rewarded with a "very good" total rating. Unfortunately, the steep price dampens the euphoria a little bit. Thus, not only the competition but also the soon-to-be-discontinued predecessor might be worthwhile considerations for bargain hunters.

Computers always had an important place in my life, starting with an Intel 80286 microprocessor in the early 1990s. I became interested in the productive side of technology, especially in campus radio, while studying at TU Chemnitz and during a trainee program in Belfast. Hardware interests led me to manage Notebookjournal.de, which is now a division of Notebooksbilliger, for a few years. I became self-employed in 2010 and took the next logical step in my career by starting to write for Notebookcheck.
