Lenovo IdeaPad 320s (4415U, HD610) Laptop Review

Mike Wobker, 👁 Sebastian Jentsch, Stefanie Voigt (translated by Katherine Bodner), 10/18/2017

Simple and affordable. Lenovo has presented the IdeaPad 320S, an affordable entry-level notebook. We have tested one of the lowest configurations available and will report how much (or how little) you can expect from a notebook that costs less than $500.

For the original German review, click here.

Lenovo is known for its wide range of notebooks. From high-quality business devices to simple laptops for home use, the Chinese manufacturer has it all. The IdeaPad 300 series is aimed mainly at buyers that are looking for small, light-weight laptops. The various configurations available cater for many different areas of use.

Our test unit is equipped with an Intel Pentium 4415U CPU. Combined with the integrated HD Graphics 610 graphics card, this device is made for simple tasks. The IdeaPad 320s has access to 4 GB of working memory. Data is stored on a 128-GB SSD. We chose similarly simple devices as our comparison units. These include the HP 17-x066ng, Acer's Aspire 1, the Asus VivoBook S X510UA and the ThinkPad E570 from Lenovo.

Please note: This configuration is not available in the US at the time of writing.

Case & Connectivity

The case of the IdeaPad 320S is mainly made from plastic. Only the display cover is aluminum. The color is called "Mineral Grey" and has a delicate grain. At first glance, this makes the surface look brushed, but it is smooth and seems to be of high quality. The gaps (where the various parts of the case were put together) are irregular, which you can see if you look closely.

While the base unit only warps under medium force, the display does so even when simply opening the computer by a corner. On the other hand, the hinges are tight and keep the display in position. It does not wobble when the laptop is moved. Lenovo has not equipped the IdeaPad 320S with a maintenance hatch.

The bottom of the base unit is fixed with ten screws and cannot be removed. Although you can lift the cover along some edges after unscrewing the screws, hooks on the inside prevent you from lifting it right off. This might be possible with more force, but we did not want to risk breaking the device beyond repair.

Input Devices

The included chiclet keyboard offers a comfortable typing experience. The pressure point is clear and the keys register strokes even when you do not hit them right in the middle. This reduces typos and you rarely have to hit a key twice in order for it to register the input.

The IdeaPad 320S is equipped with a ClickPad. You need to press very hard for the touchpad to register a mouse click and clicks are not registered at all in the top quarter of the Pad. It does react reliably to touch gestures over its entire surface. Compared to the size of the touchpad, the area where it registers a right mouse click is very small. This means that the device registered a left click when we meant to do a right click several times. Overall, the touchpad reacts very well. You will probably get used to the described details quite quickly.

Display

The IPS panel fulfills the current standard with a resolution of 1920x1080 pixels. It is bright enough to be used outdoors and contrast and black value can keep up with its competition. We were very happy with the display. Although of course color space coverage could be better, it is perfectly fine for this price range. 

From all comparison devices, our test unit is equipped with one of the better displays. The IdeaPad 320S is only available with the Full-HD IPS panel, but the devices of the IdeaPad 300 series all have various sizes, so are also available with other displays.

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
31 ms ... rise ↗ and fall ↘ combined↗ 16 ms rise
↘ 15 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 78 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (25.5 ms).
       Response Time 50% Grey to 80% Grey
42 ms ... rise ↗ and fall ↘ combined↗ 21 ms rise
↘ 21 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 53 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (40.7 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 detected 352 Hz ≤ 90 % brightness setting

The display backlight flickers at 352 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 90 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 352 Hz is relatively high, so most users sensitive to PWM should not notice any flickering. However, there are reports that some users are still sensitive to PWM at 500 Hz and above, so be aware.

In comparison: 52 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9821 (minimum: 43 - maximum: 142900) Hz was measured.

color space coverage: 61% of the sRGB color space
color space coverage: 61% of the sRGB color space
color space coverage: 39% of the Adobe color space
color space coverage: 39% of the Adobe color space

61% color space coverage of the sRGB color space and 39% coverage of the Adobe color space are a decent result for the IdeaPad 320S. They are not perfect, but most devices of this price range have similar values. The brightness is sufficient to work outdoors when the sky is overcast and the viewing angles are great. As you can see from our test image, screen content can be read well even from the widest angles.

We did register PWM during our measurements. The display flickers at 352 HZ at a brightness level of 90%.

Processor

The processor fulfills the requirements of simple everyday tasks. The Intel Pentium 3315U CPU enables a smooth system, but as soon as applications become more demanding - programs for image processing, for example - the loading times become longer.

Our test unit could only open programs slowly in the Multi-Tasking test. According to our Cinebench loop benchmark, the system managed to keep its performance consistent. We would recommend not doing too many different things at the same time on the IdeaPad 320S.

Graphics

The IdeaPad 320S's low performance continues in the device's graphics solution. The integrated Intel HD Graphics 610 is not made for graphically demanding applications and we would not even think of running 3D applications on it. We can only say the same as we already said for the processor: The IdeaPad 320S is suitable for simple tasks.

Find out how the HD Graphics 610 GPU fares compared to other graphics units in our benchmark section.

Gaming Performance

As was to be expected, the IdeaPad 320S is not made for PC games. Even older games such as "Bioshock Infinite" from 2013 cannot be displayed smoothly at minimum settings. You can probably play casual games from the Windows Store, but the entry-level device is made for simple applications, not for gaming.

Our test unit is not the only one that received this gaming verdict. All comparison devices had results that were below average in this category, as none of them are made with gaming in mind. You can compare our test unit with other graphics solutions in our Gaming benchmark section.

Emissions & Energy Management

System Noise

The IdeaPad 320S runs very quietly. The cooling fan is hardly audible even under load and in very quiet surroundings. A lot of manufacturers are currently offering very quiet devices in the low, entry-level price range. We are glad that Lenovo has also managed to produce an almost silent device.

Temperature

The IdeaPad 320S offered similar results in our stress test. We measured core temperatures of 67 °C (~152.6 °F) maximum. After the one-hour stress test, we ran the 3DMark 11 again and its result was 120 points lower than before. This is due to the extreme scenario that will probably never happen in everyday use.

Speakers

The speakers of the IdeaPad 320S sound unbalanced. Across all frequencies, you get the impression that the sounds come from far away. Bass frequencies are cut off too soon, highs held for a long time. The sound is not suitable for regularly playing media content even after some getting used to.

Power Consumption

Our test unit is very frugal concerning its power consumption: Even under load its consumption remains below 25 watts. This is a good result compared to the other devices. The included 45-watt power supply is definitely large enough for our test unit's needs.

Battery Runtime

We could not reach the 12 hours of battery runtime that Lenovo promised. We were able to surf the web for a good 7.5 hours during our practical Wi-Fi test. This is an average result for a mobile, light-weight device such as the IdeaPad 320S.

Lenovo's IdeaPad 320S is a decent device for simple tasks. Its design and connectivity are directed at practically oriented users who do not want to forego good quality while accepting low performance. We have seen worse notebooks for a similar or even higher price.

The IdeaPad 320S from Lenovo is a simple notebook with low performance, but decent workmanship.

We particularly liked the keyboard and display. The fact that the device cannot be opened without the risk of damaging the device is very bothersome, however. This limits the users' options and prevents them from cleaning the cooling fan or changing the storage device.
