MagyarLenovo IdeaPad L340-17IRH Review: The well-rounded mid-range gaming notebook is unable to reach its full performance potential
With the IdeaPad L340-17IRH, Lenovo offers a mid-range 17.3-inch gaming notebook that is targeted towards users who want a visually discrete gaming notebook. In this context, Lenovo is using the term "undercover gaming." The notebook is very similar to the IdeaPad L340-17API that we tested recently. However, there are some differences in the detail. The competitors include devices such as the HP Pavilion Gaming 17, the MSI GF75 Thin 9SC, the Dell G3 17 3779, and the Asus TUF FX705DT.
Case and Equipment - Lenovo uses plastic
The case of the IdeaPad L340 is completely made of plastic. The case color is called "granite black." The top of the base unit and the back of the lid have a brushed-metal look, and the display frame has a black color. The notebook is 10 mm (~0.4 in) thicker than the IdeaPad L340-17API we tested recently. In terms of the workmanship, there are no complaints. The clearances are right, and we do not notice any sharp edges. However, there is some room for improvement in terms of the stability. The base unit and the lid in particular should offer more stiffness. The notebook does not offer an optical drive, and you also cannot add one later, so if you need an optical drive, you have to use a USB model. This is another difference compared to the L340-17API.
The L340 also does not have a maintenance flap. In order to access the insides, you have to remove the bottom of the case. To do this, all the screws on the bottom of the case have to be removed. Then you can remove the bottom of the case by using a thin prying tool or spatula, before you get access to the solid state disk, the fans, the WLAN module, the working memory, and the battery.
The number of connections is limited. The computer offers two Type-A USB connection and one Type-C USB connection, all of which operate according to the USB-3.2 Gen-1 standard. They are accompanied by an HDMI and a Gigabit Ethernet connection. The IdeaPad does not offer a storage card reader. All the connections are placed in the back section of the left side, so the areas on both sides of the palm rests will remain free from cables.
The WLAN module uses a Qualcomm chip (QCA9377). In addition to the 802.11a/b/g/n WLAN standards, it also supports the fast ac standard. The transfer speeds we measure under optimal conditions (no additional WLAN devices in close proximity and the notebook and server PCs are within a close distance) turn out mediocre.
Connections
Input Devices - Keyboard illumination included
The IdeaPad L340 brings an illuminated chiclet keyboard that includes a number block. The flat, smooth keys offer a short stroke and clear pressure point. We like the resistance offered by the keys. While typing, the keyboard is stable and does not yield. The blue keyboard illumination is controlled by a function key. There are two steps of brightness. Overall, Lenovo offers a successful keyboard here that is suitable for everyday tasks.
The multitouch-capable ClickPad occupies an area of about 10.5 x 7 cm (~4.1 x 2.8 in), so there is a lot of space for using gesture control. The smooth surface of the pad allows fingers to slide easily. The pad also responds to input in the corners. It has a short stroke and clear pressure point.
Display - IPS on board
The matte 17.3-inch display of the IdeaPad has a native resolution of 1920x1080 pixels. While the display offers a good contrast (1514:1), the brightness turns out slightly too low (292 cd/m²). We consider values larger than 300 cd/m² to be good.
At brightness levels of 20% and lower, the display unfortunately produces some flickering at a frequency of 250 Hz. This relatively low frequency could lead to headaches or eye problems for sensitive users.

The display backlight flickers at 250 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 20 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 250 Hz is relatively low, so sensitive users will likely notice flickering and experience eyestrain at the stated brightness setting and below. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 17933 (minimum: 5 - maximum: 3846000) Hz was measured. | |||
The display of the IdeaPad offers a fairly decent color reproduction already in the state of delivery. With a DeltaE-2000 color deviation of 4.04, the target of DeltaE smaller than 3 is barely missed. In addition, the display has a minimal blue tint. The color reproduction can be improved via calibration. This reduces the color deviation to a value of 2.06, the blue tint disappears, and the grayscale is reproduced significantly more balanced. The AdobeRGB and sRGB color spaces are not covered completely. The coverage is 60 percent (AdobeRGB) and 93 percent (sRGB).
Using the color profile we are offering, the color reproduction of the display can be adjusted according to our calibration. However, you have to make sure that you have the same display model (manufacturer + model number) as our test unit, since otherwise the color reproduction can become worse instead of improving. Often displays from various manufacturers are used within one notebook model series.
The Lenovo notebook is equipped with an IPS panel with stable viewing angles, so you can read the display from any angle. Outdoors, you can only read the display when the sunlight is not too bright.
Performance - Mid-range gaming power
With the IdeaPad L340-17IRH, Lenovo has a 17.3-inch gaming notebook in its portfolio that offers sufficient computing performance for all the usual application areas. Our test unit can be purchased for about 1000 Euros (~$1109), and there are also other equipment variants. Prices start from about 750 Euros (~$832).
Processor
The IdeaPad is run by a Core i5-9300H quad-core processor. The CPU is based on the Coffee Lake architecture and runs at a base clock speed of 2.4 GHz. Via Turbo, the clock speed can be increased to 4 GHz (four cores) or 4.1 GHz (one core). Hyper-threading (two threads running per core) is supported.
The processor runs through the multi-thread tests of the CineBench benchmarks at 3.7 to 4 GHz for a short period, before the clock speed drops to between 3.2 and 3.5 GHz. However, from time to time, the processor is also throttled down to 2.4 GHz. In battery operation, the clock speed is between 2.7 and 3.9 GHz. The single-thread tests are run at 4 to 4.1 GHz in mains as well as in battery operation.
We evaluate whether the CPU Turbo can also be maintained constantly in mains operation by running the multi-thread test of the CineBench R15 benchmark for at least 30 minutes in a constant loop. From the first to the third run, the results drop slightly, but then they increase with a significant jump. Our measurements show that the Turbo fluctuates strongly during the first few runs. It only levels out at a fairly constant value later.
The results of the CB15 loop are not outstanding. Together with the Acer Nitro 5, the IdeaPad produces the worst results among the Core i5-9300H notebooks we have tested so far. The Legion Y540-17IRH, which is also made by Lenovo, produces values that are about 20 percent higher.

System Performance
The L340-17IRH does not lack performance. A strong processor and a fast NVMe SSD ensure a fast and smooth running system. They are accompanied by a mid-range GPU that is able to bring all the current computer games onto the screen. The results in the PC-Mark benchmark turn out good.
Unfortunately, Lenovo leaves part of the performance potential unused, since the working memory can only run in single-channel mode exclusively. The dual-channel mode also cannot be activated later, because the notebook only has a single slot for the working memory. However, there are also other equipment models of the IdeaPad L340 that allow using the dual-channel mode. Those model are equipped with an additional 4 GB of working memory that is soldered in.

Storage Solution
An NVMe SSD from Western Digital serves as the system drive. This is a model in the M.2-2242 format that offers 512 GB of storage space. In the state of delivery, 438 GB of that is still available, and the rest of the storage is used by the recovery partition and the Windows installation. While the transfer rates turn out good, the built-in model does not belong to the top range of SSDs. The SSD supports only PCI Express Gen3 x2 and is thus connected with two lanes. Faster models use four lanes (PCI Express Gen3 x4).

Graphics Card
The IdeaPad L340 uses a dedicated GeForce GTX-1650 graphics core from Nvidia. The GPU belongs to the GPU upper mid-range and is based on the Turing architecture. In contrast to the Turing GPUs of the RTX-2000 series, the GTX 1650 does not offer ray tracing or tensor cores. The GTX 1650 supports DirectX 12 and runs at a base speed of 1395 MHz. Via Boost, this can be increased up to 1560 MHz. If the GPU does not exceed a set temperature and power limit, even higher speeds can be achieved. We register a maximum of 1887 MHz, which can only be maintained for a short time, however. The Witcher-3 test runs at an average speed of 1671 MHz. The GPU is able to use the fast GDDR5 graphics storage (4096 GB).
The results in the 3D-Mark benchmarks range at a normal level for this GPU. The UHD Graphics-630 GPU integrated into the processor is active, and the notebook uses Nvidia's Optimus graphics switching solution.

Gaming Performance
The hardware of the Lenovo notebook is able to bring all the games that are in our database smoothly to the screen. Usually, Full HD resolution and medium to high quality settings can be used, and in some cases even more is possible. The built-in GPU is not made for resolutions beyond Full HD (you would need an external monitor). The corresponding resolutions can only be used for games that do not make very high demands on the hardware.
However, the frame rates remain behind the potential of the notebook, since the working memory can only run in single-channel mode. The difference in the frame rates between dual and single-channel mode depends on the game and the selected resolution and quality level. We recently tested the HP Omen 15 that is equipped with the same CPU/GPU combination in single as well as in dual channel mode. In dual-channel mode, up to 30 percent higher frame rates can be achieved.

In order to evaluate whether the frame rates remain mostly constant also over a longer time period, we run the game "The Witcher 3" for about 60 minutes at Full HD resolution and maximum quality settings. The character of the gamer is not moved during the whole time period. We do not detect a drop in the frame rates.

Temperature
The Lenovo notebook runs through our stress test (Prime95 and FurMark run for at least one hour) in different ways in mains and battery operation. In mains operation, the processor runs at 2.4 GHz for a short time, before the clock speed drops to 1.4 GHz and then remains at that level. The graphics core reaches speeds between 1400 and 1500 MHz. In battery operation, the clock speeds are at 800 MHz (CPU) and 800 to 900 MHz (GPU). The stress test represents an extreme scenario that does not occur in everyday operation. We use this test to evaluate whether the system also remains stable under full load.
During the stress test, we register a temperature above 50 °C (122 °F) at one measurement point on the bottom of the case. The warming turns out significantly lower while running the Witcher-3 test (the game runs for one hour in Full HD resolution and at maximum quality settings). During idle operation, the temperatures remain within the green range.
(±) The maximum temperature on the upper side is 45 °C / 113 F, compared to the average of 40.4 °C / 105 F, ranging from 21.2 to 68.8 °C for the class Gaming.
(-) The bottom heats up to a maximum of 54 °C / 129 F, compared to the average of 43.2 °C / 110 F
(+) In idle usage, the average temperature for the upper side is 26 °C / 79 F, compared to the device average of 33.8 °C / 93 F.
(±) Playing The Witcher 3, the average temperature for the upper side is 32.7 °C / 91 F, compared to the device average of 33.8 °C / 93 F.
(+) The palmrests and touchpad are reaching skin temperature as a maximum (35.5 °C / 95.9 F) and are therefore not hot.
(-) The average temperature of the palmrest area of similar devices was 28.9 °C / 84 F (-6.6 °C / -11.9 F).
Speakers
The stereo speakers are placed in the front area of the case bottom. They produce a decent sound that lacks bass, however. For a better sound experience, you have to use headphones or external speakers.

Power Consumption
The IdeaPad does not show any unusual behavior in terms of the power consumption. During idle operation, we measure a maximum power consumption of 9.6 watts, which is a good value. During our stress test, the value increases up to 135 watts. During gaming operation, the consumption is lower. While running our Witcher-3 test, we measure an average power consumption of 92 watts (86 to 102 watts). The power supply is rated at 135 watts.

Battery Life
Our realistic WLAN test simulates the load when opening web sites, based on a script. The "Balanced" profile is active, the power saving functions are deactivated, and the display brightness is adjusted to about 150 cd/m². The L340 achieves a runtime of 6:11 hours, which is a good value for a gaming notebook.
Pros
Cons
Verdict
With the IdeaPad L340-17IRH, Lenovo offers a mid-range 17.3-inch gaming notebook. The built-in combination of the Core i5-9300H processor and GeForce GTX-1650 GPU brings all the current computer games to the screen smoothly. In general, you can use Full-HD resolution and medium to high quality settings.
Thanks to its discrete visuals, the IdeaPad L340-17IRH might also be interesting beyond gaming for many users.
However, the frame rates remain below the potential of the notebook, since the working memory only runs in single channel mode. Activating dual-channel mode is not possible, since the notebook only has a single slot for the working memory.
The build-in NVMe SSD ensures a fast and smoothly running system. You should be able to replace it with a faster or higher-capacity model, but in order to do that, you would need to open the case. The matte IPS display scores with stable viewing angles, a good contrast, and great color reproduction. The brightness of the displays is okay, but should be better in a notebook of this price range.
The chiclet keyboard is proving suitable for everyday tasks. A positive point is that it offers illumination. This is accompanied by a good battery life. While the connection equipment of the notebook is not too rich, the most necessary connections are there. On the other hand, you have to make do without a storage card reader.
