Lenovo Legion Y540-17IRH in Review: Mid-Range Gamer Makes Full Use of its Core i5

Sascha Mölck, 👁 Florian Glaser (translated by Marius S.), 07/28/2019

Conspicuously subtle. Lenovo's mid-range gaming laptop is able to run all current PC games smoothly on its matte 17.3-inch screen (144 Hz, FHD, IPS), thanks to its Core i5-9300H processor and its GeForce GTX 1660 Ti graphics card. A maintenance hatch allows users to easily swap the RAM and storage. The iGPU, which is disabled by default, can be enabled via the BIOS to improve battery life.

The Lenovo Legion Y540-17IRH is a mid-range 17.3-inch gaming notebook. While its appearance is very similar to that of the Legion Y740-17ICH, there are physical differences between the two laptops. Lenovo chose an inconspicuous, neutral exterior, in order to make the notebook fit better into an office setting. Our test model is powered by a Core i5-9300H processor and a GeForce GTX 1660 Ti GPU. Alternative models with a GeForce GTX 1650 or a GeForce RTX 2060 are available as well. Its competitors include devices such as the Schenker XMG Core 17MSI GP75 Leopard 9SD, Dell G7 17 7790 and the Gigabyte Sabre 17-W8.

Case - Lenovo Relies on Plastic

Lenovo hides the Legion's hardware behind a fully black (raven black) case made of plastic. Since Lenovo omits any visual highlights, the device blends well into an office setting. The offset lid is the most prominent design element. It does not close level with the back of the device but rather protrudes by a good 25 mm (~0.98 in). The top of the base unit is rubberized. The texture on the back of the lid features grooves. Good: There is a maintenance hatch on the Legion, which allows for easy access to the SSD, the HDD bay and the RAM. In order to reach the battery, the entire bottom shell has to be removed. More on that topic later.

The Y540-17IRH cannot deny its similarity to the Legion Y740-17ICH with regards to the case - they look very much alike. The chassis is not identical, however. The Y540-17IRH's case is, for example, slightly more compact. At the same time, it is thicker by a few millimeters. That being said, the cases of both devices are low in depth, while having relatively large footprints. In the case of competitors such as the Schenker XMG Core 17 and the MSI GP75 Leopard 9SD, the relationship between these dimensions is reversed.

The laptop does not exhibit flaws in terms of build quality. Clearances are as they should be and there are no material protrusions. That being said, we expected more in terms of rigidity. The base unit yields under pressure on the surfaces next to the keyboard - this affects the left side more strongly than the right side. The base unit is also not as resistant to twisting as we would like it to be. This is particularly true for the lid. Thankfully, pressure on the lid does not lead to image distortions. The hinges hold it firmly in place, even though they tend to teeter somewhat. The lid can be opened with one hand. The maximum opening angle of the lid is 180 degrees.

Connectivity - No Thunderbolt 3

There are no surprises when it comes to the port selection of the Legion. The three available USB Type-A ports and the single USB Type-C port all adhere to the USB 3.2 Gen 1 standard. Additionally, the Type-C model features DisplayPort-via-USB Type-C (the appropriate adapter is sold separately). Combined with the HDMI 2.0 port and the Mini DisplayPort, there are three video outputs in total. There is also a combined audio jack, a Gigabit Ethernet port, and a cable lock slot. The Legion does not have a card reader at its disposal.

We are particularly unhappy with the lack of a Thunderbolt 3 port, which should come standard on a gaming laptop at this price. It could have been used for a more powerful, external GPU for example. Unlike the Y540-17IRH, the Legion Y740-17ICH does offer Thunderbolt 3.

The ports have been distributed across all three sides. Good: There is at least one USB port on each side. The ports on the right and left of the device have been placed farther towards the back. Thanks to this, it is unlikely for cables to interfere with mouse movements.

Communication

The Wi-Fi module of the Y540 contains an Intel chip (Wireless-AC 9560). Aside from 802.11a/b/g/n, it also supports the faster Wi-Fi standard ac. Furthermore, it is responsible for providing Bluetooth 5 functionality. Under optimal conditions (no other Wi-Fi devices in close proximity, small distance between laptop and server PC), we measured good data transfer rates. A Gigabit Ethernet connection from Realtek's well-known RTL8168/8111 family handles wired networking. There were no issues with it during our testing.

Accessories

The Legion's packaging contains the usual paperwork: A quick-start guide and warranty information. There is also a short SATA flat ribbon cable, which is required for the installation of a 2.5-inch drive.

Maintenance

The Y540 provides users with a maintenance hatch, which allows for easy access to the SSD, 2.5-inch bay as well as the RAM. The system memory is covered by an additional metal plate. The hatch can only be opened after unscrewing two screws. Afterwards, it can be removed. In order to access the fans, Wi-Fi module and battery, the entire bottom shell has to be removed. Although this is not very difficult in and of itself, a lot of screws have to be removed in the process. Afterwards, the bottom plates can be dislodged with the help of a sharp edge.

Warranty

Lenovo offers its customers a warranty period of two years. There are options to increase the scope and the length of the warranty. Three years of on-site warranty can be purchased for just below 60 Euros (~$67), for example.

Input Devices - Backlit Keyboard

Keyboard

The Y540 is equipped with a chiclet keyboard. The keys have been designed in typical Lenovo fashion: The user-facing sides of the keys are not straight but are curved. The keys offer medium travel and a distinct feedback. We liked the key resistance as well - although this is a matter of personal preference. Typing depresses the keyboard slightly; this did not end up interfering with the workflow however. As opposed to the Y740-17ICH (RGB lighting), the Y540-17IRH's keyboard backlight is monochromatic and white. There are two brightness levels which can be controlled via a function key. All in all, this is a solid keyboard from Lenovo that works well during daily use.

Touchpad

The multi-touch enabled touchpad extends itself over an area of about 10.2 x 5.2 cm (4.02 x 2.05 in). Thus, there is more than enough space for gestures. The smooth surface has good gliding properties. The pad responds precisely to inputs all the way to the edges. Below the touchpad, there are two dedicated mouse buttons. They offer short travel and a distinct haptic, as well as audible feedback.

Display - 144-Hz IPS

The 17.3-inch display of the Legion has a native resolution of 1920x1080 pixels. While the contrast ratio is good (1.505:1), the brightness is somewhat low (282 nits). For the latter, a value of 300 nits and above is considered good. Within our comparison, the MSI GP75 Leopard 9SD's display was able to clearly set itself apart from the competition with a brightness level of almost 400 nits.

The 144-Hz panel inside of the Y540 has fast response times overall. However, this discipline once again favors the display of the MSI GP75 Leopard 9SD - and in this case also that of the Gigabyte Sabre 17-W8. The competing 144-Hz models are able to achieve even lower response times. Good: The display of the Legion does not exhibit PWM flickering.

* ... smaller is better

Ex-factory, the Legion's screen already represents colors rather well. At 3.57, its DeltaE-2000 only narrowly misses the ideal threshold (DeltaE of 3 or less). That being said, the display exhibits a faint blue tint. With calibration, the color representation can be improved. We have tried it and achieved the following results: The color deviation was lowered to 1.31, the blue tint disappeared and the grayscale is represented much more accurately as well. The Legion is unable to achieve full color-space coverage of either AdobeRGB or sRGB. The achieved color-space coverage relative to the standards is 64% (AdobeRGB) and 98% (sRGB).

The color representation of the screen can be improved with the help of our color profile, which stems from our calibration. It is important to determine in advance whether the installed display (manufacturer + model number) matches that of our test device. Otherwise, the color accuracy may decrease instead of increase. Frequently, OEMs use displays from a few different screen manufacturers within one laptop line.

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
12.8 ms ... rise ↗ and fall ↘ combined↗ 7.6 ms rise

The screen shows good response rates in our tests, but may be too slow for competitive gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 13 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (25.1 ms).

This means that the measured response time is better than the average of all tested devices (40 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 9428 (minimum: 43 - maximum: 142900) Hz was measured.

The Lenovo laptop is equipped with an IPS panel with wide viewing angles. Due to this, the screen can be read from every position. Outdoors, screen content is only recognizable if the sun does not shine too brightly.

Performance - Core i5 in Full Force

With the Y540-17IRH, Lenovo has a 17.3-inch gaming laptop in store. It runs all current titles smoothly and does well in terms of other usage scenarios as well. The configuration of our test device can be purchased for around 1,400 Euros (~$1,561). Various other configurations are also available. The cheapest model currently costs just below 1,100 Euros (~$1,226) and comes with a GeForce GTX 1650 GPU. By contrast, more expensive models are fitted with a GeForce RTX 2060 graphics unit.

Testing Conditions

The preinstalled software Lenovo Vantage offers multiple settings, including a temperature-based mode. It controls fan usage and the performance level of the CPU. The available modes are "quiet", "balanced" and "performance". We performed our tests using the "balanced" mode. The profile "performance" did not cause a boost in performance. In "balanced" mode, the CPU's capabilities are already fully exhausted. This may not be the case for Legion models with six-core processors.

Since the UHD Graphics 630 GPU, which is integrated into the processor, is disabled ex-factory, we left it disabled during our tests as well. This leads to the GeForce GPU being permanently active. However, the iGPU can be enabled via the BIOS or the Lenovo Vantage software. Thereafter, the laptop uses Nvidia's graphics-switching technology, Optimus - this becomes particularly apparent when it comes to the battery life, which we will show at a later stage in this test.

Note: After first enabling the hybrid mode, a graphics driver has to be installed via Windows Update following a reboot of the laptop.

Processor

The Legion Y540 is powered by the four-core processor Core i5-9300H (Coffee Lake). Thus, the Legion lacks two CPU cores compared to the other devices in our comparison. In turn, our configuration of the Legion is more than 200 Euros (~$223) cheaper. The 9300H processor has a base clock of 2.4 GHz. The clock rate can be turbo boosted to up to 4 GHz (four cores) or 4.1 GHz (one core).

The processor completes the multithread tests of the CineBench benchmarks at 4 GHz and the single-thread tests at 4 to 4.1 GHz. Both values correspond to tests while on mains. In battery mode, the CPU frequency reaches 2.4 GHz (multithread) or between 3.5 and 4.1 GHz (single-thread).

By running the CineBench R15 multithread benchmarks in a loop for at least 30 minutes, we determine whether the CPU turbo is consistently active while on mains. The results were on a consistently steady level. Here, the turbo boost is in full force - this is not a standard result by any means.

Due to the lower core count, it is unsurprising for the Legion to fall far behind its competition. On the other hand, the Legion achieves the best result by far among the Core i5-9300H laptops we have tested to date. We have included the results of two 9300H laptops in the following graph.

Storage Solution

Lenovo has opted for a Western Digital NVMe SSD for the Y540. It is an M.2 2242 model with 512 GB of storage space. Ex-factory, about 440 GB is available to users. The remaining space is occupied by a recovery partition and the windows installation. While the transfer rates are relatively fast, the installed model is not one of the top SSDs on the market. It is evident that the SSD is only connected through two PCI Express lanes. That being said, the Legion supports SSDs, which are connected via four lanes, as well. The achieved transfer rates of these models are consequently higher.

Moreover, users have the option to install an additional 2.5-inch storage medium (SSD/HDD). The required SATA cable is included in the original packaging and the installation frame is located on the inside of the device.

GPU Performance

Lenovo's 17.3-inch device is equipped with a GeForce GTX 1660 Ti GPU from Nvidia. While it is based on the Turing architecture - and as opposed to the RTX 2000 series Turing GPUs - it does not offer ray-tracing capabilities or tensor cores. In the 3DMark benchmarks, the GPU achieved results that can be considered normal. Here, the GTX 1660 Ti scores higher than the GTX 1060 and not too far below the GTX 1070. In battery mode, around one third of the graphics power is accessible.

The GPU supports DirectX 12 and has a base clock of 1,455 MHz. If needed, this frequency can be boosted to up to 1,590 MHz. As long as the GPU stays below a certain temperature and/or energy consumption threshold, the performance can be increased even further. We registered a maximum of 1,845 MHz, for example, although this frequency was only maintained for a short period of time. During our benchmarks, we observed an average operating speed of 1,710 MHz. Our The Witcher 3 test was completed at 1,650 MHz. Meanwhile, the GPU has access to fast GDDR6 graphics memory (6.144 GB).

The UHD Graphics 630, which is integrated into the processor, is not active. Thus, the laptop does not use Nvidia's graphics-switching technology, Optimus, ex-factory. As mentioned earlier however, the iGPU can be enabled through the BIOS or the Lenovo Vantage software.

Gaming Performance

The CPU-GPU combination of the Y540-17IRH is able to run all of the games in our database smoothly. In the overwhelming majority of cases, the full native resolution (Full HD) can be selected. A lot is possible in terms of the quality settings as well. Typically, high to maximum detail settings can be used. The GPU is only suitable for resolutions above Full HD (for which an external display is necessary) in a limited capacity. At these respective resolutions, the quality settings consequently have to be adjusted downwards.

In order to determine whether the frame rates stay largely consistent over a longer period of time, we ran The Witcher 3 at Full HD and at the highest quality settings for about 60 minutes. During the entire time, the main playable character is not moved. We did not experience a sudden drop in terms of frame rates.

Emissions - A Lot of Noise under Load

System Noise

The two installed fans do not spin up to very high speeds during idle and under lighter loads. We registered a sound pressure level of between 32 and 34 dB(A). Ideally, fans are switched off under these conditions for completely silent operation. Under medium and high loads, fan noise ramps up very noticeably. During our stress test, for example, we were able to record a sound pressure level of 52 dB(A). During gaming, it is only marginally quieter: During our The Witcher 3 test, this value drops to 50 dB(A). Due to this, gaming is no fun without a headset.

Temperature

The Legion performs differently in our stress test (Prime95 and FurMark ran for at least an hour) depending on whether it runs in battery mode or on mains. On mains, the processor runs at 2.9 to 3 GHz, while the graphics chip runs at 1,395 MHz. In battery mode, these values drop to 1.7 to 1.8 GHz (CPU) or 1,500 to 1,800 MHz (GPU). The stress test is an extreme case that does not occur during daily use. We use this test to determine whether the system is stable under full load.

The bottom becomes particularly warm during stress. During the stress tests, we recorded temperatures in excess of 50 °C (122° F) in multiple spots. During our The Witcher 3 test, the temperatures remained slightly lower (we ran the game at Full HD resolution and maximum quality settings). In either case, using the laptop in the literal sense (on your lap) would be ill-advised. During idle, we recorded temperatures above 30 °C (86 °F) in multiple locations. This can be attributed to the GeForce GPU, which is permanently active. Idle temperatures are lower when the integrated GPU is enabled.
