Hello, guys. Today, in this article, I’m going to review the Lenovo IdeaPad L340 gaming laptop in detail.

Table of Contents

First, like other laptops I have reviewed, this one is also I received from New Delhi. So, let’s get started. But, before I proceed, read my article on an explanation of laptop specs to understand the laptop’s inside components in a better way.

Technical Specs of our Lenovo IdeaPad L340 Review Unit

  • Laptop dimensions: 36.35 x 25.5 x 2.4 cms

The Build Quality and Material

All plastic build of Lenovo IdeaPad L340 laptop.

The Lenovo IdeaPad L340 comes with all-plastic build. It's quite sturdy and solid enough despite made from Plastic. The Lenovo logo is placed on the bottom left of the plastic lid. The clean top makes it more premium compared to other laptops.

Dimensions and Weight

Dimensions of Lenovo IdeaPad L340 laptop.

The dimensions of this Lenovo IdeaPad L340 are 36.35 cms (14.31-inch) in width, 25.5 cms (10.04-inch) in depth, and 2.4 cms (0.94-inch) in height. In addition to that, I have also measured the weight using a propert weight meter. The readings are as below.

  • For laptop only: 4.78 lbs (2.2 kg)
  • For laptop + Charging cables: 5.86 lbs (2.7 kg)

Here, the motive to check the laptop with charging cables is to show you how much weight you have to carry during traveling. And, I found it thicker when compared to Dell G3 3500 (2.16 cms), Razer Blade Pro 17 (1.99 cms), MSI GS65 Stealth-004 (1.79 cms), Dell Alienware m15 R2 (2.01 cms), and Lenovo Legion 7i (2 cms).

It is lightweight to carry when compared to Razer Blade (3.55 kg), Dell G3 3500 (3 kg), Legion 7i (3.13 kg), and Dell Alienware (3.3 kg). But, found heavier than MSI GS65 Stealth-004 (2.40 kg).

Display Quality and Color Reproduction

Size and Quality

The Lenovo IdeaPad L340 laptop has 15.6-inch FHD display. It has 60Hz refresh rate and IPS panel for good delivery of viewing angles. In addition to that, the screen contrast ratio is 940:1, which is less than that of we recommend (1000:1).

It's to note that the laptop has no G-Sync available.

Color Reproduction Efficiency

Screen colour gamut of Lenovo IdeaPad L340 laptop are being measured using Spyder 5 PRO.

The results of screen colour gamut are perfectly good for normal tasks. It's good for students and office-levels jobs. But, not impressive for professional content creators like photo and video editors.

Is the display enough bright?

Display nits of Lenovo IdeaPad L340 laptop at different brightness levels.

The display of my review unit has reached 273 Nits at 100% of screen brightness at the center. The result is very similar to Acer Swift 3 SF314-57 and SF314-57G laptops.

Screen Flex

There is little more screen flex when tried to move the screen up and down using fingers. The flex is caused by the low strength of the hinge and plastic lid. But, overall, I found no issue during normal use, thanks to the average thick plastic lid.

In addition to that, My review unit has opened up with just one finger. That demonstrates the evenly distributed weight across the hinge. Also, note that initially, you gonna face some problem but, over the use, it will be resolved.

Keyboard – Tactile, Flex, Build, and RGB Backlit?

Keyboard Flex and Build Quality

Keyboard flex testing is underway on Lenovo IdeaPad L340 laptop.

Well, due to the plastic interior, I found little more keyboard flex when pressed the keyboard down hard using fingers with fair pressure. In addition to that, it was also a bit extended to the palm rest area. In my experience, I found it pretty standard like other gaming laptops. Overall, no issues during normal typing.

Furthermore, the keyboard has no highlighted WASD keys unlike Acer Nitro 5 AN515 gaming laptop.

Single Zone of Blue Backlit

The keys of the Lenovo IdeaPad L340 gaming laptop have the only single zone of 2-level blue backlit. You can also turn it off completely if you want. The keyboard backlit is bright enough to illuminate the secondary function of keys also, as you can see in the above image.

Fine Typing Experience

Typing on the keyboard of this laptop is pretty good. It gives a consistent tactile feedback. During typing, The plastic keys were traveling a consistent distance of 1.5mm.

In addition to that, the power button is placed just next to the “Multimedia” button. But, it’s not an issue since your accidental press won’t create any problem. You have to long-press the power button then after Acer software will prompt you to what to do. So, overall pretty good like other gaming laptops.

Bigger and Fairly placed 2 Arrow Keys

There are 2 arrow keys - Up and Down arrow - which are small in size and very closely placed. You may hit wrong key during gaming because of very closer placement. In Acer Nitro 5, you will get big 4 arrow keys.

Precision Touchpad

The touchpad of Lenovo IdeaPad L340 is 4.1-inch wide and uses Ellen drivers instead of Windows precision. It's smooth, accurate, and responsive. In addition, it clicks down anywhere. What my concern is about it clicks. It goes a bit more down when you press it for click. And, it also generates a bit audible sound. Overall, I think it's a little bit not good.

Furthermore, my gaming experience says that a laptop’s touchpad even if it’s a precision unit it never helps while escaping from enemies. For that, I recommend buying an external dedicated gaming mouse.

Fingerprints on the Smooth Surface

Fingerprints on the smooth matte plastic surface of Lenovo IdeaPad L340 laptop.

The smooth matte black plastic surface easily attracts the fingerprints. But, to be frank, it's pretty easy-to-clean using the micro-fiber cloth. In addition to that, thanks to the black color, I observed no color change over the use.

During my Alienware m15 R2 (White variant) review, I found it was slightly yellowish over the use, but that’s not the case with Acer Nitro 5 AN515 gaming laptop.

Processor, Graphics, and RAM

Lenovo IdeaPad L340 internals are uncovered.

Going off to the topic, Are you guys able to see the CPU and GPU chip? I have just removed the bottom cover to show you. But, I think it’s not.

Coming back to the topic, an Intel Core i5-9300H CPU and NVIDIA GTX 1050 GPU is powering the laptop. In addition to that, 2666MHz 8GB of faster DDR4 RAM is giving more than enough space for smooth multitasking.

Here, I'm missing an SSD storage. Lenovo has just placed a 1TB of 5400RPM of HDD storage.

Cinebench R20 Score

To check the CPU performance, I have conducted the 3 runs on Cinebench R20. Cinebench is a tool used to check the single and multi-core scores of CPU by performing several tests. The average of the 3 runs is in the below image.

Cinebench R20 scores of Lenovo IdeaPad L340 laptop.

The Cinebench results conclude many things like whether the CPU undervolting beneficial, buying the cooling pad is worthy, and many more.

In Cinebench R20 test, without cooling pad, the CB single and multi core scores are 421 and 1732. With the use of cooling pad, the multi core score has raised just by 1. But, with 0.15v CPU undervolting, the multi core score was raised to 1830, which is outstanding.

So, here, the CPU undervolting has shown a considerable positive impact on multi-core performance. And, the cooling pad hasn't.

Average CPU and GPU Clock Speed

The CPU and GPU clock speeds were measured by performing the stress and gaming tests in different modes. Stress tests were done with the AIDA64 tool.

And the same tool and method were used to measure the TDP, CPU and GPU temperature, laptop’s exterior temperature, and fans’ noise. So, let’s begin with clock speed.

Average CPU and GPU clock speeds during various stress test on Lenovo IdeaPad L340 laptop.

During stress test using AIDA64 at stock fan, the CPU and GPU clock speeds were 3043MHz and 1649MHz, respectively. The same test with 0.1v CPU undervolting has raised the CPU clock speed to 3261MHz and reduced the GPU clock speed to 1628MHz.

And, the addition of a cooling pad has shown quite a major change in both CPU and GPU clock speed. Both' speeds were increased to 3779MHz and 1669MHz, respectively.

So, you can see that both CPU undervolting and cooling pad is impacting heavily on laptop's performance. I've never seen such huge increment before in any laptops I've tested as of 9th July 2021.

Video Editing Performance

The video editing performance of this laptop was tested by two ways.

  • Average of the video export time
  • Multitasking during video export

Average of the video export time

In this test, I have exported the 16 minutes and 13 seconds long video in YouTube 4K H.264 preset using Adobe Premier CC. And I have repeated the same test 4 times further to show you the average result.

Video export benchmark of Lenovo IdeaPad L340 laptop.

So, during my video export test using Adobe Premier CC, this Lenovo IdeaPad L340 laptop has exported the video in an average of 15 minutes and 3 seconds. That’s pretty low-time, which is good.

Multitasking during video export

The motive to conduct this test wasn’t other than to rate the smoothness of this laptop when the CPU is busy with intense work. I have checked the following during the video export, the touchpad, keyboard, and laptop’s response time.

During video editing, I found this laptop pretty smooth. Even, smoother than Mi Notebook 14 Horizon. I'm really quite shocked with the performance of such laptop under Rs 50,000 price.

Thermal Performance

Average CPU and GPU temperature of Lenovo IdeaPad L340 during various stress tests.

So, as you can see that the CPU temperature isn't changing even if I use a cooling pad or do CPU undervolting. But the GPU temperature was reduced to 67 from 74 degrees Celsius when I have used the cooling pad.

This kind of thing happens because of shared heat pipes. If you have seen the image of uncovered internals of this laptop, you will find that there are two heat pipes are shared between CPU and GPU.

Laptop’s Exterior Temperature

At idle at an auto fan, both the palm rest and a keyboard were found pretty cool.

During the stress test, the keyboard was found at mid 46 C. The top of the base was near 43 C. At the same time, Both touchpad and a palm rest found cool. But, the use of cooling pad has reduced the temperature of keyboard from 46 to 42 degrees Celsius.

Here again, the cooling pad is found worthy for this laptop in the temperature reduction of exterior.

Fans Noise Level

The fans’ performance was tested to check the noise produced by this laptop.

Lenovo IdeaPad L340 laptop fan noise during idle state, stress test at auto fan, and gaming.

In idle mode at the auto fan, The 2 fans were at 35.1dB – completely silent. While the CPU+GPU stress tests running on at auto fan, they were at 42.8dB – slightly audible but not distracting. During the gaming, they were at 42.2dB – slightly audible compared to other gaming laptops. The fans are really much silent compared to other laptops of price under Rs 50,000.

In addition to that, the gaming laptops have the most noisy fans. If you read my review articles of Dell Alienware m15 R2, Lenovo Legion 7i, MSI GS65 Stealth-004, and Razer Blade Pro 17 gaming laptops, you will find the noise emitted by their fans was reaching 60dB. And, that’s become equal to the noise emitted by washing machine, hair dryer, and electric toothbrush. But, this one isn’t a gaming laptop. Such scenario is not the case with this laptop.

Camera and Microphone

The 720p camera and a microphone are located at the top bezel of display. The camera has a privacy shutter too. In my outdoor testings, I found both are nearly average in quality. In addition, the camera lacks support for Windows Hello unlock, which I don't even expect in the laptop of price under Rs 50,000.

Overall, I've rated both of them 5 out of 10.


Speakers of Lenovo IdeaPad L340 laptop.

The 2 speakers are located on the sides underneath the laptop.

I have used the Digitech sound level meter. It has measured the 75.1dB of the sound level while watching the YouTube video at maximum volume. For more detailed information about speakers’ quality, I have done the LatencyMon test. And, the LatencyMon results were just an average.

Air Intake Vents

Air intake vents on the back cover of the Lenovo IdeaPad L340 laptop.

The air intake vents are placed on the backside cover directly above the fan, CPU, GPU, and heat pipes. And, our thermal tests have revealed many shocking but impressive results when we've used the cooling pad. So, in this laptop, the air intake vents are really worthy.


Battery life of Lenovo IdeaPad L340 laptop.

The 45Wh 3-Cell battery lasted for 84 minutes during the continuous stress test. And, during YouTube watching at 50% of screen brightness and background apps disabled, it has lasted for 5 hours and 23 minutes.

Gaming Benchmarks
