Lenovo ThinkPad L15 Gen 4 in review: A long-lasting, silent Ryzen laptop

Business class. Lenovo's business notebook generates less noise and heat, has a long battery life, and includes an inbuilt LTE modem. It has two RAM slots in addition to a Ryzen 7 APU, which provides enough computational capability. The starting price is around $900.

The ThinkPad L series offers entry-level and mid-range business notebooks at a reasonable price. The least expensive models of this 15.6-inch notebook cost about $900. Lenovo sells versions with both AMD and Intel internals, and this model is AMD-based. The ThinkPad L14 Gen 4 is a 14-inch model that we just evaluated.

The Acer Aspire Vero AV15-53P, Schenker VIA 15 Pro M22, HP ProBook 445 G10, Fujitsu LifeBook E5412A, and Dell Latitude 3440 are among the competitors. This similarity applies more strongly to the last three laptops' respective 15.6-inch sister versions.

Case - The technology of the L15 is housed in a plastic casing

The case, characterized by its sober and functional design, is crafted from black plastic. More refined casing materials are reserved for the higher ThinkPad series. The iconic 'ThinkPad' lettering is prominently displayed on the back of the lid and the palm rest, both featuring smooth, matte surfaces. Notably, there is no maintenance flap; however, the battery (screwed, not glued) and other internals are accessible after removing the bottom shell. A positive feature is that the waste heat is dissipated on the right side of the notebook, ensuring sufficient cooling even when the lid is closed, for example, when docked.

The device exhibits no noticeable processing flaws, and the gap dimensions are correct. While the base unit can be twisted slightly too much, greater rigidity would be desirable. The lid remains within reasonable limits. Applying pressure to the back of the lid does not result in image changes, and the tight hinges securely hold the lid in position. The maximum opening angle is 180 degrees, and one-handed opening is possible.

Connectivity - The ThinkPad does not come with Thunderbolt

The notebook is equipped with two USB-A ports (USB 3.2 Gen 1) and two USB-C ports (USB 3.2 Gen 2). Notably, the USB-C ports support Power Delivery and DisplayPort functionality. In combination with the HDMI slot, the laptop boasts up to three video outputs. Additionally, it features a combined audio socket, Gigabit Ethernet, and an optional SmartCard reader to round off its connectivity options.

Communication

Under optimal conditions—such as no WiFi devices in the immediate vicinity and a short distance between the laptop and the server PC—very good WiFi data rates are achieved. The L15 is equipped with a WiFi 6E chip (Mediatek MT7922). For wired connections, it features a controller (RTL8168/8111; 1 GBit/s) from Realtek.

In addition to WiFi, wireless connections can be established via the LTE network, thanks to the inclusion of a corresponding modem (Quectel EM05-G; CAT 4, max. 150 MBit/s download, 50 MBit/s upload). The SIM card reader (nano-SIM) is located on the back of the laptop, and eSIM is also supported

Webcam

In terms of quality, the webcam (2.1 MP + IR, max. 1,920 x 1,080 pixels) provides standard performance. However, a color deviation of approximately 12 (with the target being DeltaE < 3) is a bit higher than desired. On a positive note, the camera features a mechanical cover, enhancing privacy and security.

Input devices - The keyboard could use more stability

Keyboard

Lenovo equips the ThinkPad with a backlit (two-level) chiclet keyboard, which includes a number pad. The smooth, concave keys offer a short and clear stroke. While the key resistance is acceptable, some users might prefer a crisper feel. It's worth noting that the keyboard has a slight bounce when typing. One inconvenience is the swapped positions of the FN key and the left CTRL key, requiring users to adjust their practiced hand movements. Despite this, Lenovo delivers a very good keyboard overall, well-suited for everyday use.

Touchpad

A click pad, measuring approximately 4.52 x 2.20 inches, serves as the primary mouse replacement with a short stroke and a clear pressure point. The trackpoint, also available, allows for more precise control of the mouse pointer. The three smooth-running mouse buttons accompanying it provide a clear pressure point.

Display - FHD panel with low color space coverage

Lenovo equips the ThinkPad L15 G4 with a matte, viewing-angle-stable 15.6-inch display (1,920 x 1,080 pixels) in a 16:9 format. Notably, there is no PWM flickering, and the display boasts a fairly high contrast. The brightness falls slightly below the target (> 300 cd/m²). Alternatively, the ThinkPad is available with a slightly brighter FHD touchscreen. There are no other display options.

* ... smaller is better

The display has an acceptable color representation out of the box; however, with a deviation of around 6.2, it falls short of the target (DeltaE < 3). Calibration brings the value down to 4.2, resulting in a more even display of the grayscale.

The panel is not capable of reproducing the AdobeRGB (43%), sRGB (63%), and DCI-P3 (42%) color spaces. Consequently, it may not be suitable for application scenarios that demand high color fidelity, as some competitors offer better performance in this regard.

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
19.7 ms ... rise ↗ and fall ↘ combined↗ 10.7 ms rise
↘ 9 ms fall
The screen shows good response rates in our tests, but may be too slow for competitive gamers.
In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 37 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (21.5 ms).
       Response Time 50% Grey to 80% Grey
24.4 ms ... rise ↗ and fall ↘ combined↗ 11.9 ms rise
↘ 12.5 ms fall
The screen shows good response rates in our tests, but may be too slow for competitive gamers.
In comparison, all tested devices range from 0.2 (minimum) to 636 (maximum) ms. » 29 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (33.7 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: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 17900 (minimum: 5 - maximum: 3846000) Hz was measured.

The viewing-angle-stable IPS panel allows readability from any position. Additionally, it is feasible to read the screen outdoors, provided that the sunlight is not too bright.

Performance - Ryzen is on fire

Within the ThinkPad L15 G4 series, Lenovo offers models with APUs from AMD (Ryzen 7000) as well as CPUs from Intel (Raptor Lake). In this review, we focus on an AMD-based model. The AMD models available at the time of testing range in price from $900 to $1,300.

Testing Conditions

Rather than using its own energy profiles, Lenovo employs Windows profiles, referred to as energy statuses (see table). The provided performance levels vary depending on the selected status. For benchmarks and runtime load, the 'Best performance' profile was used, while the 'Balanced' profile was employed for other runtime tests.

Best performance Balanced Best energy saving
Power Limit 1 (HWInfo) 31 Watt 25 Watt 15 Watt
Power Limit 2 (HWInfo) 40 Watt 30 Watt 20 Watt

Processor

The Ryzen 7 PRO 7730U APU, part of the Barcelo series and based on Zen 3 architecture, features eight CPU cores with a total of 16 threads, reaching a maximum clock rate of 4.55 GHz for a single core. Under continuous multi-thread load, as observed in the CB15 loop, the CPU maintains a consistently high Turbo clock.

While performance is influenced by the energy profile in use, differences between profiles are not substantial. The single-thread performance, which is more relevant for everyday use, consistently remains at a high level.

Benchmark results, when compared with the non-"PRO" variant Ryzen 7 7730U APU, indicate that the present APU values are at an average level under the 'Best performance' profile. The 'PRO' designation signifies support for AMD PRO technologies, encompassing a collection of security functions tailored for business use.

System Performance

The smoothly operating system is optimized for office and Internet applications, as well as frugal games at low settings. Some of the computing power remains untapped, as the RAM (16 GB, DDR4-3200) operates only in single-channel mode. Installing a second memory module would remedy this, activating dual-channel mode for enhanced performance.

The RAM runs in single-channel mode.

DPC Latency

The standardized latency monitor test, encompassing web surfing, 4k video playback, and Prime95 High-Load, uncovered anomalies. The system does not seem well-suited for real-time video and audio editing. It's worth noting that future software updates could potentially bring improvements or even deteriorations to the performance.

Storage Devices

The system drive is a 512 GB SSD (PCIe 4, M.2-2242) from SK Hynix, delivering overall good data rates. Being installed in a PCIe 3 slot, it falls short of its full potential. A positive note is the absence of thermally induced throttling. It's important to highlight that only SSDs in the M.2-2242 format are compatible, excluding the more common M.2-2280 models. Unfortunately, the L15 does not provide space for additional SSDs.

The system drive is a PCIe SSD, and the L15 can only accommodate M.2-2242 format SSDs, not the more common M.2-2280 models.
