The Construct High quality and Materials

All plastic build of Lenovo IdeaPad Slim 3 laptop.

Lenovo IdeaPad Slim 3 laptop computer comes with all-plastic construct. The show lid accommodates emblem on the right-bottom as an alternative of the middle, that offers a reasonably clear look. All edges and corners are additionally rounded and that displays fairly premium high quality. The construct isn’t totally different than Lenovo IdeaPad Slim 3i (Intel version).

Dimensions and Weight

The size of this laptop computer are 32.7 cms (12.87-inch) in width, 24.1 cms (9.5-inch) in depth, and a couple of cms (0.8-inch) in top. The load of this laptop computer was measured utilizing a propert weight meter. And, it’s for

  • Laptop computer solely: 1.6 kg (3.53 lbs)
  • Laptop computer with charging equipment: 1.85 kg (4.07 lbs)

The aim of measuring the load with equipment is to offer you an concept in regards to the weight that will want to hold whereas touring.

This laptop computer is heavier than different laptops of value underneath Rs 50,000 like Asus VivoBook 14 X415JA and HP 15s-Eq0500AU.

Show High quality and Coloration Copy

Measurement and High quality

14-inch FHD IPS display of Lenovo IdeaPad Slim 3 laptop.

The 14-inch 1080 60Hz refresh-rate IPS non-touch show is surrounded by virtually 7.5mm thick bezels. It has good viewing angles, because of the IPS panel. So, it has a greater one when in comparison with Dell 14 3493 (WVA panel), Lenovo IdeaPad S145 (VA panel), and VivoBook M513 (VA panel).

Along with that, the IPS show has beneath a mean screen contrast ratio of 811:1. At Thanalysis, we suggest at the very least 1000:1 of distinction ratio for the show for higher color accuracy.

Coloration Copy Effectivity

Screen colour gamut of Lenovo IdeaPad Slim 3 laptop

As you possibly can see that SRGB is 56%, AdobeRGB is 36%, and NTSC is 33% for Lenovo IdeaPad Slim 3i laptop computer. The screen colour gamut outcomes are too beneath than normal required for skilled photograph and video enhancing. Nevertheless, the show isn’t dangerous for college students, office-level duties, programmers, bloggers, and different content material writers.

Is the show sufficient shiny?

Display nits of Lenovo IdeaPad Slim 3 laptop at different levels of screen brightness.

The show nits at 100% brightness stage are simply 248, which low. At Thanalysis, we suggest at the very least 300 nits for the show to correctly see the content material of display throughout solar gentle.

Display Flex

When deliberately moved the display up and down utilizing arms, I discovered somewhat little bit of flex there. However to be frank, it wasn’t downside for me.

Along with that, the hinge runs principally alongside the bottom and that is what I believe contributed extra within the show flex discount. Whereas attempting to open the show with one finger, I failed. It’s essential to need to put your second hand on the bottom to open this machine. So, that demonstrates the inconsistently distributed weight throughout the hinge.

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

Keyboard Flex and Construct High quality

The keyboard is fabricated from plastic and has plastic island. The keys are additionally of identical materials. The keys have grey color and white fonts. However, the keys are simply seen. Nevertheless, at Thanalysis, we typically suggest the black keys with white fonts.

Whereas pushing it down laborious utilizing fingers with truthful stress, I discovered little flex there. However, I confronted no points throughout regular use, not even throughout aggressive use. If you wish to go for a laptop computer with virtually no keyboard flex, then go for Dell Inspiron 14 3493.

General, by way of keyboard flex and construct high quality, I discovered it fairly good.


It’s a bit awkward that this keyboard has no backlit. A keyboard and not using a backlit account extra minutes in battery life, however you should have an issue throughout typing in a low ambient room.

If backlit considerations extra for you then, it’s higher to go together with Asus VivoBook M513. It has a 3-level of single zonal white backlit. Different laptops like HP 15s-Eq0500AU and Lenovo IdeaPad L340 have additionally backlit keyboard underneath simply Rs 50,000 value.

Tactile Suggestions?

Typing expertise consists of many issues like tactile suggestions, clicky keys, typing noise, shallow feeling for poorly designed keyboard, and lots of extra.

Throughout typing, I discovered the keys have been touring 1.45mm distance down. The keys are giving constant tactile suggestions. The keys have been actually clicky.

Along with that, the ability button is positioned at top-right of the keyboard like Lenovo IdeaPad Slim 3i laptop. It is truly remoted from the keyboard. In order that, there will not be unintentional mistaken press. And, it has an LED gentle too.

Small and Messy 2 Arrow Keys

The two arrow keys (Up and Down arrow) are smaller and positioned fairly shut to one another. Such a placement at all times led to unintentional mistaken press. And, like Dell laptops, Lenovo IdeaPads, and ThinkPads, I at all times complain about these small arrow keys.

However, they aren’t an issue for workplace use. And, this isn’t a gaming laptop computer. Therefore, you don’t have to think about it necessary.

Precision Touchpad?

4.1-inch Non-precision plastic touchpad of Lenovo IdeaPad Slim 3 laptop.

This 4.1-inch wider plastic touchpad is easy and responsive. It isn’t Home windows acknowledged precision unit. Along with that, it does click on down anyplace. It is fairly correct at dealing with gestures aside from zoom gestures. I’ve observed some type of inaccuracy in detecting the zoom gesture. Nonetheless, I like to recommend shopping for a dedicated mouse.

Fingerprints on the Clean Floor

Fingerprints on the surface of the Lenovo IdeaPad Slim 3 laptop.

After utilizing this Lenovo IdeaPad Slim 3 for nearly 7 days, I discovered the fingerprints have been proven up however, they have been seen as the graceful plastic matte end has a blue coloration. However, you possibly can simply clear the floor utilizing a micro-fiber fabric. Along with that, I discovered no coloration change within the inside over the use.

I’m telling this as a result of whereas reviewing the Alienware m15 R2 gaming laptop computer, I discovered its white inside barely yellowish at some half. Additionally, it was laborious to scrub. However that’s not the case with this machine.


Lenovo has outfitted an 8GB of Single Channel 2666MHz DDR4 RAM which will also be upgradable to 12GB. So, a fairly massive quantity of RAM so that you can make the multitasking higher and smoother in comparison with a 4GB RAM.

Moreover, Twin channel RAM provides higher efficiency than the Single channel one. Asus VivoBook Ultra 15 has Dual channel 3200MHz DDR4 RAM.

Processor and Graphics

AMD Ryzen 5-3500U 4 Core 8 Thread processor and AMD Radeon Vega 8 GPU is powering the efficiency of this laptop computer. The CPU has a base velocity of two.1GHz which will be boosted to the utmost of three.7GHz.

Along with that, this laptop computer has additionally 512GB of SSD storage. In order that, you possibly can open and edit giant information easily and really quick.

Now, let’s verify a few of the CPU benchmarks.

Cinebench R20 Rating

I’ve taken 3 runs of Cinebench to indicate you a mean of it. Moreover, Cinebench is a software used to measure CPU efficiency.

Cinebench R20 single and multi core scores of Lenovo IdeaPad Slim 3 laptop.

In a Cinebench R20 take a look at, the only core and multi core scores have been 377 and 1378, respectively throughout checks and not using a cooling pad. With the usage of a cooling pad, the CB R20 multi core rating has raised simply by 1. However, with 0.15v CPU Undervolting, the multi core rating has raised to 1411.

So, it clearly signifies that the cooling pad is ineffective for this laptop computer by way of efficiency increment.

Now, the query is what these scores inform.

Initially, Throughout the testing, Cinebench R20 places an extreme load on the CPU to execute the duties. By doing so, it can verify machine’s cooling resolution additionally which different software doesn’t aside from 3DMark. So, when the CPU comes underneath a heavy load, thermal throttling takes place within the processor and it reduces the efficiency.

For instance, In case your CPU has max clock speeds of 4.5GHz, then you’ll attain 4.1GHz max throughout gaming or stress checks. The rationale for not selecting up the restrict is thermal throttling. So, If the Cinebench R20 rating of the laptop computer is excessive means the laptop computer has excessive highly effective CPU with a greater thermal administration.

Now, let’s verify Geekbench benchmarks.

Geekbench 5 Scores

Geekbench 5 single and multi core scores of Lenovo IdeaPad Slim 3 laptop.

When examined this laptop computer utilizing Geekbench 5, the Lenovo IdeaPad Slim 3 laptop computer has scored 994 for single core and 3481 for multi core.

Now, what does this rating inform?

It tells the efficiency of the laptop computer. The upper the rating, the upper the efficiency. Right here, it’s important to think about the multi core rating. Look, Geekbench doesn’t put an extreme load on the CPU like Cinebench R20. And, Geekbench think about primarily productiveness duties like emailing, searching, multitasking, and and so on to guage the {hardware}.

And, such methods can’t offer you an concept in regards to the cooling resolution. As a result of tiny duties doesn’t make a lot weight on the CPU. Therefore, If the laptop computer has increased Geekbench multi core rating means its functionality for productiveness is a lot better. However, on the identical time, details about thermal throttling and cooling resolution will stay unanswered by this software.

Therefore, for players and programmers, Geekbench isn’t a software to guage the laptop computer. It’s higher to think about Cinebench right here. And, for regular customers or workplace customers, this one appears to be getting the job carried out.

The GB 5 scores of this laptop computer are average-good.

Common CPU Clock Velocity

The CPU clock velocity was measured by performing the stress take a look at utilizing AIDA64. The outcomes of a mean of three runs are within the beneath picture.

Average CPU clock speeds of Lenovo IdeaPad Slim 3 laptop.

Throughout stress take a look at at auto fan, the CPU clock was recorded 2837MHz. With addition of the cooling pad within the second trial, the clock velocity was raised to 2846MHz. And, with additional 0.15v CPU undervolting, it is raised to 3178MHz.

So, it mainly tells that CPU undervolting is far more helpful than a cooling pad for this laptop computer. It is higher to not purchase a cooling pad as a result of it is practically a waste of cash.

Along with that, It’s ineffective to measure the GPU clock velocity. As a result of it’s built-in on the identical silicon board. It’s not for heavy duties. Therefore, it’s higher to skip. Moreover, this Lenovo IdeaPad Slim 3 machine is neither a gaming machine nor it has even MX collection GPU. So, it’s void to conduct the TDP (Thermal energy design) take a look at.

As gaming requires extra sources, it’s develop into worthy of measuring the TDP and other ways to cut back it. However that’s not the case with this machine.

Video Enhancing Efficiency

The video enhancing efficiency of this laptop computer was examined by two methods.

  • Common of the video export time
  • Multitasking throughout video export

Common of the video export time

On this take a look at, I’ve exported the 16 minutes and 13 seconds lengthy video in YouTube 4K H.264 preset utilizing Adobe Premier CC. And I’ve repeated the identical take a look at 4 instances additional to indicate you the typical outcome.

video export benchmarks of Lenovo IdeaPad Slim 3 laptop.

So, throughout my video export take a look at utilizing Adobe Premier CC, this Lenovo IdeaPad Slim 3 laptop computer has exported the video in a mean of 38 minutes and 21 seconds. That’s an excessive amount of.

Multitasking throughout video export

The motive to conduct this take a look at wasn’t aside from to charge the smoothness of this laptop computer when the CPU is busy with intense work. I’ve checked the next through the video export, the touchpad, keyboard, and laptop computer’s response time.

So, Throughout this take a look at, I discovered this laptop computer virtually laggy. Because it has no devoted NVIDIA graphics, not even of the MX collection, the expectation of excellent efficiency is ineffective. It is fairly below-average when in comparison with Lenovo IdeaPad L340 gaming laptop (Price Rs 50,000).

Thermal Efficiency

This take a look at was carried out to inform you whether or not the cooling pad is environment friendly in temperature discount with secure or elevated efficiency. For the stress take a look at, I’ve used the AIDA64 software. So, the outcomes are within the beneath picture.

Average CPU temperatures during various modes of stress tests on Lenovo IdeaPad Slim 3 laptop.

At idle, the CPU was 49 levels C scorching. In a stress take a look at at an auto fan and not using a cooling pad, the CPU temperature was discovered at 81 levels Celsius. With a cooling pad, its temperature was lowered to 80 diploma Celsius. And, with 0.15v CPU UV, the temperature was additional decreased to 77.3 levels Celsius. So, that’s the results of a mean of three runs.

So, the cooling pad has proven no noticeable change in temperature discount. It is higher to not purchase it.

Laptop computer’s Exterior Temperature

At idle at an auto fan, each the palm relaxation and a keyboard have been discovered fairly cool.

Throughout the stress take a look at, the keyboard was discovered at mid 42 C. The highest of the bottom was close to 46 C. On the identical time, Each touchpad and a palm relaxation discovered cool. And practically an identical outcomes obtained when used the cooling pad.

Right here, once more, the cooling pad is discovered unworthy for this laptop computer.

Followers Noise Stage

Fan noise of Lenovo IdeaPad Slim 3 laptop during different modes of stress test.

This Lenovo IdeaPad Slim 3 laptop computer has just one fan aside from Lenovo IdeaPad L340, like, in different laptops in ₹50,000 price range.

At idle, the fan’s noise was 33.2dB – fully silent, even than different laptops I’ve examined. Throughout the stress take a look at, it was 44.3dB louder. So, Within the convention room, this laptop computer gained’t distract you and the man sitting subsequent to you.

Along with that, the gaming laptops have probably the most noisy followers. In case you learn my evaluation articles of Dell Alienware m15 R2, Lenovo Legion 7i, MSI GS65 Stealth-004, and Razer Blade Pro 17 gaming laptops, you can see the noise emitted by their followers was reaching 60dB. And, that’s develop into equal to the noise emitted by washer, hair dryer, and electrical toothbrush. However, this one isn’t a gaming laptop computer. Such situation isn’t the case with this laptop computer.

Digital camera and Microphone

The 720p camera and microphone are at the top bezel of the display.

The 720p digital camera and microphone are situated on the best bezel of display. The digital camera has a privateness shutter, which has impressed me. When examined each of them out of doors, I discovered microphone normal in high quality whereas digital camera is below-average. I’ve rated digital camera 4/10 whereas microphone 5/10.

In such situation, I am unable to anticipate the digital camera to help Windows Hello unlock.

Audio system

Back of the Lenovo IdeaPad Slim 3 laptop.

The two down-firing audio system of this laptop computer are situated on front-side beneath the laptop computer.

I’ve used the Digitech sound stage meter. It has measured the 83dB of the sound stage whereas watching the YouTube video at most quantity. For extra detailed details about audio system’ high quality, I’ve carried out the LatencyMon take a look at. And, the LatencyMon outcomes have been simply a mean.
