Lenovo ThinkBook 15 Gen2 Laptop review: Affordable Tiger Lake laptop

Good maintenance options. With the ThinkBook 15, Lenovo already presented a solid work device one year ago. Now the second generation of the office laptops also wants to convince in everyday operation with many equipment options and Tiger Lake CPUs. Our review clarifies how well it succeeds in this.
Mike Wobker, 👁 Andreas Osthoff (translated by Mark Riege), 🇩🇪 🇮🇹 ...
Lenovo ThinkBook 15 Gen2 ITL

We did not note any grave shortcomings in our verdict on the test of the Lenovo ThinkBook 15 about one year ago. According to our initial impression, this also won't be the case in the ThinkBook 15 Gen2. Since nothing has changed in the external equipment characteristics except for the connections, we will refer to the predecessor model in the corresponding sections of our review.

Our current test configuration is available for about 720 Euros (~$868) and includes an Intel Core i5-1135G7 with its internal Intel Iris Xe Graphics G7 80EUs graphics unit. This is accompanied by 16 GB of working memory and a 512 GB SSD. In this configuration, the Lenovo laptop is compared with the competing devices listed below. Underneath each section, you can also add more laptops from our database.

Equipment - ThinkBook 15 now with Thunderbolt 4

In the second generation of the ThinkBook 15, Lenovo foregoes the USB-A connection that was hidden behind a flap. On the other hand, one of the USB-C ports now supports Thunderbolt 4, allowing for numerous expansions. The separate power connection has also been removed, and it can now be charged using one of the USB-C ports.

Security

Lenovo has equipped the ThinkBook 15 Gen2 with a fingerprint sensor that is integrated into the power button, a mechanical webcam cover, and a TPM 2.0 module.

Maintenance

With a little bit of patience, the ThinkBook 15 can be opened after all the screws on the bottom of the case have been removed. Inside is a replaceable RAM module below a cover. In addition, there are two M.2 slots for SSDs, only one of which is occupied in our test configuration.

Display - Bright enough indoors

In our test unit, the display of the ThinkPad 15 Gen2 is a 15.6-inch IPS panel that offers a resolution of 1920 x 1080 pixels. Even though at 276 cd/m² on average, the maximum brightness is the highest in our test field, it can only be considered rather low overall. At 87%, the brightness distribution turns out slightly better. Our recording in a dark room also shows some quite pronounced screen bleeding at the top and left edge of the display. Lenovo does not use PWM for brightness control.

Our measurements attest the display of the ThinkBook 15 Gen2 with a good contrast ratio of 1108:1 and an only slightly elevated black value of 0.28 cd/m². At 60% (sRGB) and 38.1% (AdobeRGB), the color space coverage also corresponds to the expectations in this device class.

The CalMAN analysis also shows that the display reproduces colors with low deviations already in the state of delivery. However, a calibration still brings an improvement of the DeltaE 2000 value from 3.8 to 1.2.

The relatively low brightness becomes noticeable when working outdoors. This means that on sunny days, you can only easily recognize the display contents when you work in a shady place.

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
30.4 ms ... rise ↗ and fall ↘ combined↗ 17.2 ms rise
↘ 13.2 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. » 76 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (24 ms).
       Response Time 50% Grey to 80% Grey
40 ms ... rise ↗ and fall ↘ combined↗ 21.2 ms rise
↘ 18.8 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. » 47 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (38.1 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: 52 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 14825 (minimum: 5 - maximum: 2500000) Hz was measured.

The viewing angles of the IPS panel of the Lenovo ThinkBook 15 Gen2 are very stable. The display contents can be recognized from almost any viewing angle without the image or colors becoming distorted.

Performance - Tiger Lake with a good constant performance

Lenovo offers the 2nd generation of the ThinkBook 15 with processors of varying powers from Intel's Tiger Lake generation. An AMD model is also available, and for increased demands on the graphics performance there is also an option with Nvidia's GeForce MX450 graphics unit. All the equipment configurations are very well suited for various office applications and also suited for simple image or video processing.

Processor

Our test configuration of the Lenovo ThinkBook 15 Gen2 is equipped with an Intel Core i5-1135G7. This processor has four cores, allowing it to operate on up to eight threads simultaneously. However, the available performance depends largely on the configured TDP and the cooling system. Despite not having the maximum TDP, the i5-1135G7 here is able to use its performance very well in our benchmarks, achieving better results than the i5-1135G7 in the Acer Aspire 5 A515.

Compared to the Honor MagicBook 15 with an AMD Ryzen 5 4500U, the ThinkBook 15 Gen2 also fares very well. While the multi-core performance of both CPUs is almost at the same level, the Intel Core i5-1135G7 is able to score the better single-core performance.

Our Cinebench R15 constant loop also reveals that the performance of the i5-1135G7 in the ThinkBook 15 Gen2 drops by about 5% right after starting the test. However, it is then able to maintain that value until the end of the test loops. Under constant load, we also determine a PL1 value of 28 watts.

Graphics Card

The Intel Iris Xe Graphics G7 80EUs used here is an internal graphics unit that is suited for low to medium demands on the graphics performance. Due to the 16 GB of working memory in dual-channel configuration, the performance should turn out slightly better than that of laptops with single-channel RAM. However, the values achieved in the 3DMark tests are slightly below average.

Our GPU benchmark list shows how other laptops with this graphics unit fared in our tests.

Noise Emissions

During everyday office usage, the fan of the ThinkBook 15 Gen2 remains mostly turned off. Even though it is clearly audible at up to 40 dB(A) under load, the even whirring can be easily ignored as background noise. We did not notice any coil whine or other noises in our test unit.

Temperature

Stress test
Stress test

Our measurements attest the ThinkBook 15 Gen2 with surface temperatures of up to 46 °C (115 °F) under load. The warmest spot is in the center towards the back at the bottom, so the palm rests always remain cool. This means that using the laptop on your lap, for example, is still barely possible.

During the hour-long stress test, the temperatures inside the laptop rose up to 89 °C (192 °F). The clock speeds of the CPU could be maintained at about 2.4 GHz on average, meaning that they didn't go lower than the basic clock speed, so users don't need to expect any limitations in everyday operation due to temperatures being too high.

Power Management - Disappointing battery life of the ThinkBook

Power Consumption

The ThinkBook 15 Gen2 demonstrates a higher power consumption than the rest of the laptops in our test field. Only the average value under load is exceeded by the predecessor model. In the stress test, the maximum power consumption quickly levels out at ~52 watts, so the included 65-Watt charger is sufficiently sized.

Battery Life

In our realistic WLAN test, the Lenovo ThinkBook 15 Gen2 achieves a battery life of about 5.5 hours. With this, it does not last as long as the rest of the devices in our test field. The predecessor model also ran more than an hour longer with the same battery capacity.

In addition to the 45-Wh battery used here, the ThinkBook 15 Gen2 is also available with a 60-Wh battery.

Lenovo continues to develop the ThinkBook discretely, mainly using more modern hardware inside. Corresponding to the configuration, it is able to use its performance well, mastering various office tasks without any problem. And if the storage or working memory become too tight at some point, both of these components can be expanded or replaced. In terms of the connections, the manufacturer has left out some of the options, replacing them with a Thunderbolt 4 port. This allows you to expand it in various ways using the corresponding adapters or docking stations.

The Lenovo ThinkBook 15 Gen2 offers a good performance for various office applications, but the battery life turns out a bit tight.

The Lenovo ThinkBook 15 Gen2 gives only few reasons for complaint. Webcams that generally have a resolution that is too low are not a problem that is particular to this device. So there is really only the short battery life that turns out significantly shorter than that of the predecessor model and our selected competitors. If the ThinkBook Gen2 sometimes has to last for a whole day without charging it, you should definitely pick a version with the 60-Wh battery. 

Price and Availability

The Lenovo ThinkBook 15 Gen2 can be purchased in this or other configurations from Campuspoint in Germany, for example. In the US, it is available from Lenovo directly, with the Intel version starting from $948 (some more affordable configurations are currently unavailable) and the AMD version from ~$630, among other places.

I carried out my first IT experiments with a 386-based system and a whole 4 MB RAM. This was followed by work on various PCs and laptops that I maintained and repaired for friends and acquaintances. After training to become a Telecommunications Systems Technician and gaining a few years of experience, I graduated with a Bachelor’s degree in Industrial Engineering. Currently, I pursue my fascination for IT, technology, and mobile devices by writing reviews and articles for Notebookcheck. I have also worked for Gamestar, Netzwelt, and Golem, among others.
