Lenovo ThinkPad L15 laptop review - Decent office companion with high system performance

AMD upgrade. Lenovo's ThinkPad L series includes inexpensive business laptops that have been able to convince in the past with good input devices and quite high-quality workmanship. The current 15-inch model in the series seeks to carry on this tradition while dramatically improving system performance with the new AMD Ryzen 7 Pro 4750 at the same time. We will clarify in the following review whether the final concept works.
Marius Schell, 👁 Andreas Osthoff (translated by Stephanie Chamberlain), 🇩🇪 🇵🇹 ...

The ThinkPad L15 is an affordable office laptop from Lenovo's ThinkPad L series. The 15-inch successor to the ThinkPad L590 is a solid entry into the world of business laptops. It's based on the current AMD Ryzen 7 Pro 4750U, which should provide a noticeable leap in performance compared to its predecessor. Our device is a campus model; a special version for the education sector at a reasonable price, but at around 850 Euros (~$1,005) it doesn't include an operating system. A comparable, unrestrictedly available configuration that includes an operating system can be purchased for about 1,060 Euros (~$1,253).

Case - Solid base, sensitive lid

With its slightly narrower display bezels, the laptop looks a bit more stylish and modern than its predecessor. Although the ThinkPad L15 can't quite keep up in this regard with the almost borderless displays found in the more expensive competitors, the fact that it's a relatively modern laptop is clearly noticeable.

The case is made entirely of plastic, and the ThinkPad logo with its illuminated red dot and a Lenovo logo adorn the back of the lid. The surfaces are made of matte, rough plastic, which makes the laptop very susceptible to fingerprints. The higher-quality ThinkPads of the E and T series, on the other hand, feature higher-quality plastic/aluminum or carbon fiber cases. The design is simple but not dull due to a few cleverly placed elements. Workmanship also offers no cause for criticism, as the gaps are uniformly small, and there's no visible excess material.

The base unit appears robust for a plastic construction. The rest of the case stability is also acceptable, but the lid and hinges in particular aren't designed to withstand strong applications of force. The hinges allow a maximum aperture angle of 180 degrees and are evenly rigid independently of this.

Compared to its predecessor, the ThinkPad L590, the ThinkPad L15 has shrunk slightly in every dimension. That's probably thanks in large part to the slightly narrower display bezels, which make the laptop look a bit more modern overall. Accordingly, the weight of 1.98 kg instead of 2.019 kg has also decreased a bit. Compared to the rest of the class, the dimensions and weight place it in the midfield.

Connectivity - Normal-size HDMI connection and Ethernet port

The connections are distributed on both sides, and the layout has remained unchanged compared to the previous model. In contrast to many other laptops, you get a full-fledged HDMI 1.4b connection and a Gigabit Ethernet port. In addition, the ThinkPad L15 can be connected to various docking stations via the so-called "Side Dock". There are two USB-A (3.1 Gen 1) and two USB-C ports (1x 3.1 Gen 2, 1x 3.1 Gen 1) available. Most ports, including the USB-C charging port, are located on the left side, which makes it easier to use an external mouse. Since the ports are placed relatively far apart from each other, cables shouldn't block nearby ports.

SD card reader - Slightly above the average

In the test with our 64 GB UHS-II reference memory card, the Toshiba Exceria Pro M501, the SD card reader in our ThinkPad L15 reaches slightly above-average speeds. Except for the Latitude 15 5510, which almost poses a threat to the XPS 15 in this discipline, the remaining comparison devices are at a similar level.

Communication - WLAN 6, Bluetooth 5.1, and optional WWAN

The Intel 9260 of the predecessor has been updated to the AX200 WLAN module on the ThinkPad L15, offering WLAN 6 and Bluetooth 5.1 support. While performance for receiving data is roughly average, it's slightly below average for sending data at 895 Mb/s. A WWAN slot is also optionally available.

Security - Webcam shutter and Ryzen Pro functional features

Alongside a fingerprint scanner and TPM 2.0, the ThinkPad model also supports smart cards and Kensington locks. It also has a mechanical webcam shutter and hardware-based Ryzen Pro security features.

Accessories - Docking solutions separately available

Apart from the power adapter, warranty information, and the laptop itself, there are no extras included in the box. Optionally, the manufacturer's online store offers many accessories such as carrying cases, external peripherals, adapters, and docking solutions. The latter extend the range of interfaces with additional video outputs and USB ports, among other things.

Maintenance

Since there's no maintenance hatch, in order to gain access to the internal components, you have to loosen 9 cross-head screws, remove the SIM drawer, and loosen some plastic clips with a thin plastic object. Afterwards, the bottom cover of the base unit can be removed. Inside, you have access to both RAM slots, the battery, the SSD, the WLAN module, and (if present) the WWAN module.

Warranty - Extension options up to 5 years

Lenovo honors buyers of the ThinkPad L15 with a standard one-year warranty. The campus model is an exception offering 3 years. The warranty can be extended up to 5 years with various options. For higher-end models, such as the ThinkPad T series, the manufacturer provides a full 3-year warranty as standard.

Input devices - Outstanding keyboard

Keyboard

The keyboard extends over the full width of the base unit and offers a number pad. The layout looks well thought-out, and except for the page up and page down keys, all keys, including the arrow keys, are normal-sized. The sound when typing can be described as being between quiet and moderate, so that it's not bothersome in quiet environments. The keyboard surface hardly gives way when typing. The two-stage keyboard backlighting illuminates all symbols and is sufficiently bright. The key travel is relatively deep, and the pressure point is clearly perceptible. The caps lock, mute, and microphone keys each signal their current status via an illuminated dot on the key. All in all, the keyboard is comparable to the keyboards on much more expensive laptops and thus well suited for longer typing tasks.

Touchpad and TrackPoint - Dedicated mouse buttons

The touchpad extends over an area of 10 x 7 cm and has three dedicated mouse buttons. In addition, left and right clicks can be triggered by pressing the left or right half of the ClickPad. While the plastic touchpad has good gliding properties and high precision, the separate mouse buttons feel quite cheap due to their inaccurate pressure point and low resistance. Using the TrackPoint works very well after a little getting used to.

The 15.6-inch IPS display has a native resolution of 1920x1080 pixels (Full HD) and an aspect ratio of 16:9. The matte layer prevents glare. Alternatively, potential buyers can also choose an HD TN panel with a resolution of 1366x768 pixels or a touchscreen version of the Full HD display with 300 cd/m². We generally advise against the TN panel, as the savings don't usually justify the drastic loss of quality on the display. Unlike some competitors, the ThinkPad L15 omitts the use of PWM for brightness control.

At 240 cd/m², the brightness of our test device is relatively low, but it's still roughly in line with the manufacturer's specification of 250 cd/m². Our test configurations of the ThinkPad E15, the HP ProBook 455 G7, and the 450 G7 also only offer slightly more brightness, respectively. The brightness distribution is quite even at 89%. For indoor use, the available brightness level is sufficient, but for outdoor use, you should rather look at certain HP ProBook models, since displays at up to 1,000 cd/m² are available within this product series.

* ... smaller is better

The black level is only 0.15, which is lower than on all other comparison devices. The resulting contrast ratio of 1,660:1 is also a top value in comparison to devices in this class. The subjective impression is convincing too, since the overall image looks authentic, and dark areas in pictures or films are reproduced very well.

The color-space coverage of the sRGB and AdobeRGB color space is 56.8% and 36.1%, respectively. These values are typical for inexpensive office laptops where other aspects such as workmanship and input devices have a higher priority. However, together with the massive color deviations, the panel is unsuitable for image-processing.

Due to the low brightness of only 240 cd/m², outdoor readability is very limited in most situations. Therefore, you should stay in the shade if possible when using the device outdoors, since the user experience is still most likely to be acceptable here due to the matte panel.

Display Response Times

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.
       Response Time Black to White
31.2 ms ... rise ↗ and fall ↘ combined↗ 17.2 ms rise
↘ 14 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 79 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (24.2 ms).
       Response Time 50% Grey to 80% Grey
48 ms ... rise ↗ and fall ↘ combined↗ 24.4 ms rise
↘ 23.6 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 636 (maximum) ms. » 76 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (38.4 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM not detected

In comparison: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9644 (minimum: 5 - maximum: 151500) Hz was measured.

Viewing angles
Viewing angles

As is typical for IPS panels, the viewing angles are excellent, and the colors and contrast are hardly altered, even when being viewed from steep angles. However, the observed brightness decreases slightly at very steep angles.

Performance - Fast Ryzen 7 processor

Our configuration of the ThinkPad L15 is a relatively powerful version that not only handles everyday office life but also multimedia and games with low system requirements without problems. At the heart of our test configuration is the AMD Ryzen 7 Pro 4750U with integrated RX Vega 7 graphics. Intel-based alternatives with the Intel Core i7-10510U or Core i5-10210U as well as cheaper models with the Ryzen 5 4500U are also available. In terms of memory, you can choose between configurations with 8 GB or, as in this case, 16 GB. In our test device, a RAM module with 16 GB is used; it runs in single-channel mode. Lenovo doesn't offer dedicated graphics cards within this laptop series.

Processor

The Ryzen 7 Pro 4750U is an AMD processor from the current Renoir generation. The eight Zen 2 cores have a base clock rate of 1.7 GHz, while the Turbo clock speed reaches up to 4.1 GHz. Compared to the Ryzen 7 4700U, the "Pro" chip offers certain hardware security features and SMT (simultaneous processing of two tasks by one processor), but the base clock is slightly lower.

In the Cinebench R15 multi-thread benchmark, the clock speed is about 4.2 GHz (TDP 30 watts) for a short time, then it drops quickly to 3.0-3.1 GHz (25 watts) and settles at 2.8 to 2.9 GHz (22 watts) after a few minutes.

In our Cinebench loop test, it sets itself far ahead of the Intel competition and also leaves the AMD Ryzen 7 4700U of the HP ProBook 455 G7 behind. Performance drops minimally at the half of the test time.

In general, the CPU performance is slightly below the average of the Ryzen 7 Pro 4750U in the single-thread-based benchmarks, and it tends to be slightly above the average in the multi-thread benchmarks. In our comparison, the processor often reaches peak values.

Full performance is also available on battery power.

System performance - Lightning-fast despite wasted potential

Although the overall system performance is very good for an office laptop, it's not always enough for one of the first three places in our comparison. These results are probably due to the dedicated graphics cards in some competitors and the single-channel RAM of our test device. The CPU also lags slightly behind an average Ryzen 7 Pro 4750U from our database. In practice, none of this is noticeable: programs are launched quickly, the system runs smoothly, responsiveness is excellent, and no hardware or software problems were encountered either.

Storage - Fast 1 TB SSD

In our configuration, the Western Digital PC SN730 1 TB NVMe SSD serves as the system drive. Users have 922 GB available out of the box. Compared to the competition, the speed is very high for 4K writes and also decent for reads, but the Samsung, Crucial and SK hynix SSDs in the ThinkPad E15HP ProBook 450 G7, and Acer TravelMate P215 are a bit faster here. The SSD in our test model consistently lies ahead of the other comparison devices in sequential reading and writing.

Graphics card - Powerful iGPU

GPU-Z
GPU-Z

The AMD Radeon RX Vega 7 is an integrated graphics solution from AMD. Compared to Intel's iGPU competition, it's about twice as fast, because Intel still relies on the outdated UHD Graphics 620. The situation is different when compared to the HP ProBook 455 G7 AMD competitor or rather to the result of an average RX Vega 7: The deficit can also probably be explained by the RAM here, which only runs in single-channel mode.

Our test model passes the Fire Strike load test with a frame-rate stability of 99.3%.

Gaming performance

The ThinkPad L15 isn't designed for gaming, but thanks to the current integrated graphic card, many games are at least playable on low settings.

Emissions - Quiet in idle usage

Noise emissions

In idle usage, the system fan is deactivated. Under low load, the fan has to start if necessary, but even then, it only generates a maximum of 30.3 dB(A). Moreover, in our stress test, the noise level of the fan immediately rises to 32.3 dB(A), and after about 5 minutes, this value increases to 34.3 dB(A). The fan behavior of the ThinkPad L15 can be characterized overall as sluggish, which results in the laptop being relatively quiet, both subjectively as well as compared to the competition.

We didn't notice any coil whine during our time with the ThinkPad L15.
