Where to buy?

The Build Quality

All-plastic body of Lenovo IdeaPad S145 laptop.

The Lenovo IdeaPad S145 has all-plastic body. But, it's pretty solid and sturdy enough. The design is a mix of modern and classic look. It's attractive.

In addition, the fingerprints do show up on the smooth matte silver finish. But, you can easily clean it using micro fiber cloth. And, I have also noticed no colour change in the surface even after long continuous use.

Dimensions and Weight

The dimensions of this Lenovo IdeaPad S145 are 13.4-inch in width, 10-inch in depth, and 0.8-inch in height. In addition to that, I have also measured the weight using Propert's weighing scale.

  • Laptop only: 1.85 kg (4 lbs)
  • Laptop + Accessories: 1.935 kg (4.3 lbs)

Here, I have checked the laptop's weight is its charging accessories, so that, you can get an idea about the total weight you may need to carry while travelling. When compared it with other laptops under Rs 60,000 in India, I found this IdeaPad S145 a bit heavy. At LaptopRadar.In, we consider laptop below 1.5Kg lightweight.

Display

15.6-inch FHD VA display of Lenovo IdeaPad S145 laptop.

The Lenovo IdeaPad S145 laptop has a 15.6-inch FHD display with 60Hz refresh rate. In addition, it delivers a little bad viewing angles because of VA panel. The screen contrast ratio is 1100:1, which is higher than our lower recommendation (1000:1). The display is surrounded by 7.5mm side bezels to make you feel more premium and also gives you higher screen-to-body ratio.

In case of this laptop, I have no option to check for G-Sync availability because it has no NVIDIA GPU. It's not a dedicated gaming laptop. But, it can fulfil your gaming needs up to certain limit.

To check the screen colour reproduction, I have tested screen colour gamut using Spyder 5 PRO. And, here are our results of 3 tests for SRGB, AdobeRGB, and NTSC.

Screen colour gamut of Lenovo IdeaPad S145 laptop's display.

As you can see the screen colour gamut are not impressive for content creators like photo and video editors. But, perfectly fine for office-level jobs, students, programmers, and bloggers.

See in the below chart where this laptop in the comparison of other laptops of price under Rs 60,000.

Screen colour gamut of Lenovo IdeaPad S145 laptop compared with other laptops of price under Rs 60K.

As you can see our dear Lenovo IdeaPad came second-last in the comparison. Too bad.

In addition to that, I have also tested the brightness of this laptop in terms of display nits. And, here are my results.

Display nits of Lenovo IdeaPad S145 laptop at different brightness levels.

So, At LaptopRadar.In, our review unit has reached almost 227 nits, which is very far-below from the minimum value we recommend (290-300 nits).

When compared it with other laptops under Rs 60,000 price, Lenovo IdeaPad S145 has secured fourth-last position and that's pretty disappointing.

To check the screen flex, I have intentionally moved the screen up and down using fingers. I found a little bit of flex there but, to be frank, it wasn't an issue for me.

Lenovo IdeaPad S145's 180-degree hinge.

In addition, the hinge runs mostly along the base, which is also responsible for minimum amount of screen flex. And, it also allows you to turn the display 180-degree right back to the keyboard.

It is to note that I got success when I have tried to open the display with one finger. That shows the even-distribution of weight across the hinge.

Keyboard

Keyboard of Lenovo IdeaPad S145 laptop.

The keyboard of Lenovo IdeaPad S145 laptop has a plastic island. So, it's not as strong as metal one but pretty sturdy and solid enough. There is a little flex when I have pressed it down hard using fingers. But, to be frank, it's not problematic for me.

In addition, the keyboard has no backlit. So, you may have to face problem while typing in the low-light room.

Typing on the keyboard of Lenovo IdeaPad S145 laptop.

When it comes to typing experience, I found the keys were not giving tactile feedback and travelling inconsistent distance between 1.2 to 1.4mm. In addition, the "Power" button is placed next to the "Next Play" button. So, you may hit it frequently while typing. But that won't be issue since you have to long-press it to execute the function assigned to it.

In addition, the keyboard has got two small up and down arrow keys, which are also incorrectly placed. Overall, this full-size keyboard isn't good but rather falls on disappointing side.

If I compare it with Mi Notebook 14 Horizon, Acer Swift 3 SF314-57, Asus VivoBook S14 S403JA, then this one will definitely go down.

Touchpad

4.5-inch wider touchpad of Lenovo IdeaPad S145 laptop.

The 4.5-inch wider touchpad of the Lenovo IdeaPad S145 laptop is made of plastic. It's smooth, responsive, and accurate. But, it doesn't support Windows precision drivers.

It clicks anywhere hence it has not separate button for left and right clicks. In addition, it bends more when pressed, but it's not problematic. However, for gaming, it's not a good. You have to buy a dedicated gaming mouse.

RAM

The Lenovo IdeaPad S145 laptop comes with 8GB of 2400MHz DDR4 Single Channel RAM. And, it's upgradable to 12GB.

In addition to that, below I have compared it with the RAM of other laptops of Rs 60,000.

  • Mi Notebook 14 Horizon: 8GB DDR4 | 2666MHz | Single Channel | No upgrade option (read full review)
  • Acer Swift 3 SF314-57: 8GB DDR4 | 2400MHz | Dual channel | Upgradable up to 32GB (read review)

  • Dell Inspiron 14 3493: 8GB DDR4 | 2666MHz | Single channel | Not upgradable
  • Acer Aspire 3 A315-23: 8GB DDR4 | 2666MHz | Single channel | Upgradable to 12GB

CPU and GPU Performance

The Intel Core i5-1035G1 CPU from Ice Lake family and Intel shared GPU is powering the laptop's performance. In addition, it got 512GB of PCIe-based SSD storage. So that, you will be able to open and edit large files smoothly.

CPU and GPU Benchmarks

To check the performance CPU, I have conducted the Cinebench tests. Cinebench score represents the CPU's performance.

Lenovo IdeaPad S145 Cinebench R20 scores.

During the Cinebench R20 test with and without cooling pad, I found not considerable change. It directly indicates that the cooling pad isn't effective in performance increment of the laptop.

In addition to that, see in the below where this Lenovo IdeaPad S145 is, when compared to other laptops of price nearly Rs 60,000.

Lenovo IdeaPad S145 single core score compared with other laptops under Rs 60,000 price.

So, in the CB single core score comparison, the Lenovo IdeaPad S145 has did a remarkable job. It's at 2nd position.

Lenovo IdeaPad S145 Cinebench R20 multi core score compared with other laptops under Rs 60K price.

So, in the CB multi core score comparison, our review unit has reached 4th position, which is outstanding. Such great position reflects the good internals and pretty efficient cooling solution.

In addition, I have also checked Geekbench 5 benchmark performance.

Geekbench 5 scores of Lenovo IdeaPad S145 laptop.

In a test by Geekbench 5, the Lenovo IdeaPad S145 laptop has achieved 1069 score on single core and 3851 score on multi core. See where it's when compared with other laptops under Rs 60,000.

Geekbench 5 single core score of Lenovo IdeaPad S145 compared with other laptops under Rs 60K price.

So, our dear Lenovo laptop is at good position when it comes to Geekbench 5 Single core comparison. Despite same processor, Mi Notebook 14 Horizon (review), Asus VivoBook 15 M513, and Acer Aspire 3 A315-23 have shown poor performance.

Geekbench 5 multi core score of Lenovo IdeaPad S145 compared with other laptops under Rs 60K price.

Again, the IdeaPad S145 has impressed me.

Now, what does this scores tell?

It tells the performance of the laptop. The higher the score, the higher the performance. Here, you have to consider the multi-core score. Take a note that, Geekbench doesn’t put an excessive load on the CPU like Cinebench R20. And, Geekbench considers mainly productivity tasks like emailing, browsing, multitasking, and etc, to evaluate the hardware.

And, these ways cannot give you an idea about the cooling solution. Because tiny tasks don’t make much stress on the CPU. Hence, If the laptop has a higher Geekbench multi-core score means its capability for productivity is much better. But, at the same time, information about thermal throttling and the cooling solution will remain unanswered by this tool.

Average CPU and GPU Clock Speeds

The Lenovo IdeaPad S145 has Intel Core i5-1035G1 which has a base speed of 1.0GHz and can be overclocked to 3.6GHz.

The average CPU and GPU clock speeds were measured by performing the stress test using AIDA64 tool. The average of 3 runs is in the below image.

Average CPU and GPU clock speeds measured by AIDA64 tool during stress tests on Lenovo IdeaPad S145 laptop.

During the stress test at auto fan with and without a cooling pad, the CPU speed was 3376MHz. Again, no change has been detected in performance because of cooling pad. It gives you an idea that cooling pad is completely useless to buy for this laptop for performance increment.

Furthermore, as Lenovo IdeaPad S145 is not a gaming laptop, I don't have to check it for TDP as it isn't required here. I would have done it if this was a gaming laptop.

Video Editing Performance

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 benchmarks of Lenovo IdeaPad S145 laptop.

So, during my test of video export in 4K preset, the Lenovo laptop has ended up in on average 30 minutes and 41 seconds. That’s too much.

I'm much disappointed because of performance during video export. Till now, I have criticised the Mi Notebook, but I think I've to praise it in this section. Also, it's worth to mention that Lenovo laptop wasn't all-time smooth during video editing.

Thermal Performance

I've performed the thermal performance test using AIDA64 tool to check whether a cooling pad is useful in temperature reduction or not.

Average CPU and GPU temperature measured during stress tests on Lenovo IdeaPad S145 laptop.

Again, the cooling pad has shown zero effect in the temperature reduction. It indicates that no cooling pad are made for this IdeaPad S145. That's the only outcome of this test.

Furthermore, in the following chart, I have compared the temperatures of laptops measured during stress test at an auto fan.

Lenovo IdeaPad S145 CPU temperature compared with other laptops under Rs 60K price.

In the CPU temperature comparison, this laptop is found at second-last position. That also reflects the a little bit inefficient thermal management.

In addition, I have also checked for laptop's exterior temperature.

  • At idle: Keyboard and palm rest were cool.
  • During stress test at auto fan: Palm rest was cool and Keyboard was at mid 40 degrees C. The exterior above the function keys was hot.
  • With the use of cooling pad: The same results to just above test.

Noise Emitted by Fans

At idle, the fan was completely silent. But, during stress test at auto fan, the noise level was increased like blast - 47.1dB.

In addition, also find Lenovo's position in terms of fan noise emission when compared to laptops of price under Rs 60,000.

Although the position of IdeaPad is 3rd, it's still not good.

You can see in the above chart that Acer Swift 3 SF314-57 comes with the most silent fan whereas Dell Inspiron 14 3493 has the most noisy fan when I ran the stress test at auto fan.

Camera and Microphone

The 720p camera and microphone are placed at the top bezel of the display. When tested both outdoor, I found both are average in quality. Both got ratings 5 out of 10. In addition, the camera of this laptop also doesn't support Windows Hello unlock.

Here is the position of this IdeaPad S145 when compared with other laptops of Rs 60,000 price.

Speakers

The 2 down-firing speakers are placed underneath the laptop front-side. They sound below-average. When I have tested the sound level while YouTube videos were on, the Digitech has shown 86dB of reading. In addition to that, the speakers also feel a bit tiny.

On the right side, there are the following ports from left to right.

  • 1 3.5mm audio/combo jack
  • 1 Full-size SD card reader

On the back, there are only air exhausts. And, on the back cover, it has air intake vents. But, in the thermal test has revealed that they're useless even when I have used a cooling pad.

Battery

The Lenovo IdeaPad S145 laptop has 35Wh battery.

It has lasted for 52 minutes during the continuous stress test and for 265 minutes while watching YouTube videos at 50% of screen brightness, keyboard backlightings off, and background apps disabled.

Storage

Let me tell you that this Lenovo IdeaPad S145 has a 512GB of PCIe-based SSD storage. I have measured its speed and performance using CrystalDiskMark. CrystalDiskMark is a tool most popular for the measurement of storage's performance.

Lenovo IdeaPad S145 SSD Storage speed test results.

You can see that it's too fast at reading and writing. The reading speed is almost 1589MB/sec and writing speed is almost 862MB/sec.

Furthermore, neither this laptop is capable of gaming nor, it has at least NVIDIA’s MX series GPU. So, I have skipped testing the gaming benchmarks.

Final Thoughts

The Lenovo IdeaPad S145 is a classic design and all-plastic build laptop. It's bit heavy but offers good performance when tested using several standard benchmarks like Cinebench R20 and Geekbench 5. It's good for programmers when it comes to performance. But, the keyboard is disappointing. The touchpad is normal but doesn't support Windows precision drivers, which should for the laptop under Rs 60,000 price. The display has no IPS panel and therefore lacks good viewing angles. However, I'm impressed with its contrast ratio. The laptop has no dedicated graphics, means, it's certainly not able to fulfil your gaming need. The speakers are enough loud. For video conference, this Lenovo IdeaPad S145 has average quality camera and microphone. In addition, it has not even a USB Type-C port, that has really scared me. Overall, this laptop is an entry-level machine.
