Lenovo ThinkPad E15 Gen.2 Review: Office laptop with an AMD chip and new design
The Lenovo ThinkPad E15 features a new, compact design with smaller screen bezels. Currently, the E15 Gen.2 is only available with AMD processors. As of yet, there are no second-generation E15 models with Intel CPUs. Lenovo offers a student discount for the model that we are reviewing, which has the following designation: 20T9S00K00. Students and teachers can pick up this model of the E15 Gen.2 for 700 Euros (~$832). It features a Ryzen 7 CPU with a Vega 7 iGPU, 16 of RAM, 512 GB of solid state storage and an IPS display. However, it does not include an operating system. This same model with an OS costs about 870 Euros (~$1035) without the student discount.

Case - AMD E15 is now more compact
All in all, the design of the ThinkPad E15 Gen.2 is quite similar to that of the first-generation E15 models, which are still available, but only with Intel CPUs. The housing is made of the same materials. However, the screen bezels of the E15 Gen.2 are smaller, and the device itself is more compact. The height (18.9 mm) has not changed. In day-to-day use, it is difficult to notice any difference between the second-gen and first-gen models of the E15. In terms of the weight, the E15 Gen.2 is comparable to other competing devices. Here, only the Schenker Via 15 stands out with its relatively low weight of 1.4 kg (3 lbs).
The chassis is still made of plastic and the display lid of aluminium. The display lid is very susceptible to fingerprints, which is why it will have to wiped clean quite often. The rigidity of the E15 Gen.2 is on a normal level for this kind of device.
Connectivity - ThinkPad E15 comes with the bare minimum
The somewhat more compact E15 Gen.2 loses one USB 3.0 port on the left, even though there is plenty of space for such a port there. The selection of ports reflects the overall low price of the laptop. It is similarly poor in both Intel- and AMD-powered models. Models with an Intel chip do not feature a Thunderbolt 3 port, and AMD models come with an HDMI 1.4b output instead of HDMI 2.0. There is an outdated USB 2.0 port on the right side.
Communication - Wi-Fi 6 thanks to an Intel module
The ADM model of the ThinkPad E15 uses a Wi-Fi 6 module from Intel. The AX200 supports all current Wi-Fi standards as well as Bluetooth 5.1. In our standardised Wi-Fi test with the reference-grade router from Netgear (Nighthawk RAX120), the E15 Gen.2 achieved good data transfer rates. We did not encounter any issues during our Wi-Fi test.

Maintenance - Significant differences inside
Once the bottom cover is removed, the differences inside between the E15 Gen.1 and the E15 Gen.2 become apparent. The 2.5-inch drive bay has been replaced with an additional M.2 slot. There is also an additional heatpipe inside. In order to get to the RAM, the additional coverings will have to be removed.
Input Devices - Solid ThinkPad keyboard
Despite its low price, the E15 offers a good keyboard with a numeric pad. Typing on the E15 feels quite satisfying, thanks to a very clear actuation point. Moreover, the keyboard also offers a backlight, which is why typing in dimly lit environments should not be a problem. The power button is located above the keyboard and features an integrated fingerprint sensor.
The keyboard also comes with the TrackPoint, which is a hallmark feature of ThinkPads. Moreover, there are three hardware buttons below the space key. Once users get used to operating the little red nob, moving the cursor with it will be quite easy. Buyers can also use the ClickPad for this. It can be clicked in the lower half. The sound that it produces is very deep and satisfying. Because of the additional numeric pad, the ClickPad was moved slightly to the left, which is why it might take some time for certain users to get used to it.
Display - E15 with a matte Full HD screen
The ThinkPad E15 Gen.2 features a matte Full HD IPS display. However, the panel of the E15 Gen.2 comes from AUO as opposed to BOE. There might be some natural variation, but this should not be much of a problem, especially given the fact that Lenovo sources screens from different manufacturers for almost all of its models.
The specifications sheet betrays the fact that the E15 Gen.2 is a low-end device. It claims a screen brightness of 250 cd/m², but in reality the brightness is slightly lower. The black value and the contrast ratio are quite good. However, white colours appear somewhat grainy and there is some noticeable screen bleeding in the lower right corner and along the bottom of the screen. All in all, the display is good enough for a cheap office notebook. Howbeit, in very bright rooms it might not be bright enough to comfortably read. There is no PWM flickering.

Right of the box, the IPS panel provides a poor colour reproduction. Moreover, the screen suffers from a blueish colour cast as our analysis with X-Rite's i1Pro spectrophotometer and CalMAN software reveals. The colour cast can be removed through calibration. However, this comes at the cost of a slight drop in brightness. The poor colour reproduction and poor colour space coverage make the E15 unfit for any sort of professional photo/video editing.

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8705 (minimum: 5 - maximum: 343500) Hz was measured. |
The matte screen surface helps quite a bit outdoors, but the low display brightness still remains a problem. The screen is only legible under an overcast sky. The viewing angles of the IPS panel are on a good level.
Performance - 8 cores and SSD
Processor - E15 with a Ryzen 7 4700U
Lenovo offers several AMD processors for the E15 Gen.2, amongst which is the very fast Ryzen 7 4800U with 8 cores and 16 threads. Our review device features the Ryzen 7 4700U, which comes with 8 cores and 8 threads. Readers can learn more about it here.
The TDP fluctuates between 30 and 28 watts, and the maximum all-core frequency amounts to 3.3 GHz. This is why the ThinkPad E15 Gen.2 is twice as fast as the E15 with a Core i7 CPU in the multi-core benchmarks. The Ryzen 7 chip in the HP ProBook 455 is also somewhat slower, because it has a lower TDP.
However, the E15 Gen.2 cannot maintain its full performance under continuous load as the results of our Cinebench multi-core loop show.
On battery power, the TDP is limited to 28 watts, which is why the performance is slightly lower. All in all, the processor is powerful enough for an office notebook.

Graphics Card - Vega 7 with dual-channel RAM
The Ryzen 7 processor ships with the fast integrated Radeon RX Vega 7 chip, which can reach its full potential, thanks to dual-channel RAM. In the synthetic 3DMark benchmarks, the iGPU is actually faster than the dedicated Radeon RX 640 in the ThinkPad E15 Gen.1. The Vega 7 graphics chip is powerful enough for all multi-media applications.
On battery power, the GPU performance does not decline and we saw no performance drops in the Fire Strike stress test (99.2 %).

Emissions - Quiet and hot
System Noise
Just like other ThinkPads, the E15 Gen.2 is very quiet. Even under load, the fan noise is not very loud. However, it is rather high-pitched, which is why it feels louder than it actually is. When idle and under low load, the E15 Gen.2 is usually completely silent. We did not hear any abnormal sounds such as coil whine coming from our review device.

Temperature
Despite an additional heatpipe, under load the E15 Gen.2 gets just as hot as the E15 Gen.1 with the Intel CPU and dedicated AMD GPU. This can be attributed to a lower fan speed. On the underside, the 60-°C (140 °F) mark is exceeded. The E15 Gen.2 gets too hot for an office notebook. Under load, the bottom of the device becomes too hot to touch. At the top of the chassis, the surface temperatures reach around 45 °C (113 °F). These temperatures are not critical, but are still quite warm.
During our stress test the TDP amounted to 27 watts. The CPU ran at 2.5 GHz and the integrated GPU at 800 MHz.
(-) The maximum temperature on the upper side is 46.5 °C / 116 F, compared to the average of 34.3 °C / 94 F, ranging from 21.2 to 62.5 °C for the class Office.
(-) The bottom heats up to a maximum of 67.3 °C / 153 F, compared to the average of 36.8 °C / 98 F
(+) In idle usage, the average temperature for the upper side is 25 °C / 77 F, compared to the device average of 29.5 °C / 85 F.
(+) The palmrests and touchpad are reaching skin temperature as a maximum (33.9 °C / 93 F) and are therefore not hot.
(-) The average temperature of the palmrest area of similar devices was 27.6 °C / 81.7 F (-6.3 °C / -11.3 F).
Speakers
The two stereo speakers on the underside of the device can only be described as mediocre. They fulfil their purpose and sound good enough for conferences, but they become quickly overwhelmed if you try to use them to listen to music or watch movies. Here we recommend using external speakers or headphones.

Energy Management
Energy Consumption
When idle, the AMD version of the ThinkPad E15 draws more power than the Intel model. However, under load the AMD variant consumes slightly less power despite providing more performance. The 65-watt power adapter should have no trouble supplying the device with enough energy.

Battery life
Even though Lenovo changed the form of the battery in the E15 Gen.2, the capacity remains the same (45 Wh). Because of a higher power draw when idle, the battery runtimes of the AMD model are slightly shorter than those of the Intel variant. In our Wi-Fi test, the E15 Gen.2 lasts 7 hours with the screen brightness set to 150 cd/m² and 6 hours with with the screen brightness maxed out. The Intel model lasts 30 minutes longer in this test. In the video test, the AMD version lasted 9 hours, while the Intel model lasted 10.5 hours. Under load, the battery died after 1 hour, because the processor does not throttle down.

Pros
Cons
Verdict - E15 Gen.2 is a low-priced office laptop that offers a lot of performance
The ThinkPad E15 Gen.2 is a good office laptop, which has a very reasonable price. The somewhat more compact design is a welcome development. However, users will only be able to notice any difference between the second-gen and the first-gen devices in direct comparisons. Because the E15 is an entry-level business notebook, it features a poor selection of ports, which includes an outdated USB 2.0 port.
The display is also rather subpar. The E15 Gen.2 has a matte IPS panel with a passable colour reproduction. However, the screen brightness is very low. 250 cd/m² is often not enough in very bright rooms. Moreover, the display is not accurate enough for professional photo/video editing.
A lot more performance, but still extremely high temperatures: With the Ryzen 7 4700U, the AMD model is much faster, but Lenovo still needs to improve the screen and the cooling.
When compared to the Intel model, the AMD version offers a lot more performance and the integrated Vega 7 graphics chip can keep up with the dedicated Radeon RX 640 GPU. Under load, we would prefer to hear more fan noise, because 60 °C (140 °F) is simply too high for an office notebook.
