Lenovo IdeaPad S340

Lenovo IdeaPad S340

Lenovo is known among other things for its long battery life in notebooks. The IdeaPad S340 fits seamlessly into the range. With its fast and large SSD, the notebook is interesting for everyone who values mobile working.

Scope of Delivery

Lenovo stays true to its line with the IdeaPad S340 and only adds the bare essentials to the notebook itself. This means that you’ll find a charger including cable and two small booklets in the box. One is the setup guide and the other a warranty booklet.
On the positive side, Lenovo, like most of its notebooks, does without unnecessary plastic in the packaging.


The design is simple and without frills. The IdeaPad S340 is kept in a dark blue. The keyboard is dark gray, which gives a good contrast to the blue. Lenovo largely dispenses with any decorative elements in this model. No logo on the display lid or any front. There is only a small grey Lenovo logo on the right front. There is simple notebooks like, I like this decision by Lenovo very much.

The large touchpad is located in front of the keyboard. As the keyboard has a complete number pad, it has moved slightly to the left. The keyboard itself is smooth-running and offers a soft typing feel. It takes some getting used to, but after a while it is pleasant to write on.

The small and inconspicuous power button is located between the display and keyboard in the upper right corner. It has a small LED that shows you if the device is running when the display is off.

The display frame is slim on three sides. It is relatively wide at the bottom, but that’s not negatively noticeable. At the top it is a bit wider than on the sides, because the webcam is still located there. There is a Privacy Shutter, with which you can cover the cam completely. With this you can be really sure that nobody is watching you secretly.

The notebook case is mostly made of plastic. The underside is quite torsionally stiff, but the upper side is quite thin. Therefore it gives way very easily if you type with a little pressure. It’s not critical, but at first it’s an irritating feeling.

The display lid, on the other hand, is made of aluminum and simply feels valuable. The drawback with aluminum is clear – it magically attracts fingerprints. The workmanship is flawless. All gaps are even and there are no burrs or edges to get caught on.


There are sufficient connections. On the left side you have the 3.5mm jack, the USB-C port, the HDMI port and the power connector. On the right side there are some status LEDs and the two USB-A ports.

So you are ready for most of the normal applications. It would have been nice if there had been a USB-C port with DisplayPort support instead of the USB 3.1 Gen1 Type-C. This would have extended the connection possibilities even more


A matt IPS panel with Full HD resolution is used in this IdeaPad. With a diagonal of 15.6″ this results in a PPI value of 141, so that your content is displayed in a nice and sharp way. Thanks to the matt surface, there are no problems with reflections. The IPS panel also allows you to benefit from wide viewing angles. Lateral viewing, if necessary, is no problem.

As in most notebooks designed for Office, the color space coverage isn’t particularly high. To be more precise, the IdeaPad S340 clearly takes last place in our database with just 55% sRGB, 39% NTSC and 41% AdobeRGB coverage. These values are sufficient for everyday office use. Everything that has something to do with color fidelity in any form should better be done on another notebook, though.

The display moves on average in terms of brightness. We measured 202 cd/m² on average. This is neither particularly bright nor too dark. The differences in the illumination of the individual display areas are quite small and not noticeable in everyday life. The contrast could be a bit higher, but it is easily sufficient for everyday use.


Windows 10 Home is pre-installed on this notebook. Apart from the Windows 10 common bloatware like Candy Crush, there are hardly any annoying programs. However, this notebook also comes with McAfee – and tries to convince you in a penetrating way that it makes sense to get the full version. If you don’t feel like it, you can uninstall it completely.

Lenovo Vantage is installed to keep your system up to date without much effort. With this app you can check for updates and make settings for system behavior. For example, music pauses when a call comes in via Skype.
On the SSD, you have 442 GB free on delivery from the 512 GB.


The IdeaPad S340 is designed for office use. And here it does all its work quietly and reliably. The hardware makes sure that programs are loaded quickly and that the data is available to you quickly. Multitasking runs smoothly and you can switch smoothly between tasks.

The SSD is fixed and reaches values of 1522 MB/s write and 1191 MB/s read in the AS SSD benchmark. Of the notebooks in our database with similar hardware no other model reaches these values. You can see the IdeaPad S340’s performance in the individual benchmarks in the graphics.
The IdeaPad S340 has a dedicated graphics card, the MX230. This is clearly noticeable in all graphics-heavy applications.


There is no reason to complain about the battery life. The IdeaPad S340 lasts a bit more than five and a half hours in the benchmark at full brightness with just under 200 cd/m². Thus, it is in the top group of comparable notebooks in our database.

If you turn the brightness down a bit, you’ll surely manage a working day with the IdeaPad without having to hang on to a power outlet.

Noise / Temperature (Overheating)

You won’t hear the Lenovo IdeaPad S340 in normal use. It quietly and silently does its job. Even with demanding programs, the fans only give a sign of life from time to time.
It’s only marginally louder in the stress test. The temperatures don’t move into a critical range. The CPU warmed up to an average of 67° Celsius. The graphic card also remained in the green area with 64° Celsius on average.

As you will hardly reach the stress levels of a stress test in everyday life, you don’t have to worry at all about the temperatures.

It also stays pleasantly cool on the outside. The notebook only warms up in front of the display. But since you’ll only rarely have your fingers there, this is negligible.


This is pleasingly easy with the IdeaPad S340. You simply have to loosen nine screws on the bottom and then you can easily remove the base plate. You have direct access to all important components.

The RAM is hidden under a small cover, which you can simply remove. On this model 4 GB RAM are soldered. A maximum of 12 GB RAM is supported, so you can add an 8 GB latch.

The M.2-SSD from Western Digital can be exchanged directly. Just make sure that the new SSD has the right format. Here is a M.2 2242 installed. In addition, there is a free 2.5″ slot in which you can install a suitable HDD or SSD. And if the battery runs out, you can also replace it, because it is not glued, but only screwed.


The sound is fine for a notebook. As with all notebooks, the IdeaPad S340 is height-oriented. The lows go down for lack of resonance space. Middles and highs are in a reasonable relationship to each other, whereby the highs are a bit more dominant than the middles.

If you turn up the volume fully, the trebles become even more dominant. However, they don’t sound shrill. This is definitely a plus. At half volume you have a reasonable sound, which is suitable for Skype, occasional music or one or the other movie.


The notebook leaves a positive, even if not unclouded impression in the test. It is stable, it is quiet, it is cool, it is fast and the battery lasts a long time. There’s also nothing to complain about in the workmanship. Another positive aspect is that you can easily and quickly upgrade it if necessary. Weight and dimensions are also okay for a notebook of this size. You can easily store it even in full pockets. The display is a point of criticism, though. It offers only little contrast and could definitely be brighter.

Lenovo would currently like to see about 950 euro* for the IdeaPad S340 on the counter. In view of the equipment, this is a reasonable price.

Lenovo ThinkPad E590

Lenovo ThinkPads have a reputation for being rugged and reliable workhorses. The ThinkPad E590 with Intel Core i5 is no exception. It can convince in almost all areas in the test and only has small weaknesses.

Scope of Delivery

The scope of delivery is manageable. In the box you’ll find the ThinkPad E590 with USB-C charger and a bit of paperwork. It consists of a warranty booklet and the setup guide.


There are no surprises in the design of the ThinkPad E590. It’s instantly recognizable as a ThinkPad. There are also no surprises in the material. The notebook is mainly made of a robust and torsionally stiff plastic. You won’t find any creaky spots here.

In comparison to the current thin bezel notebooks, the display frames look relatively unfashionable. But they fit the device and underline the robust impression that the ThinkPad E590 makes. You’ll find the 720p webcam in the upper display bezel and a Lenovo logo and type designation on the lower bezel.

Because the ThinkPad comes with a number pad, the touchpad is slightly offset to the left. But that doesn’t disturb typing in any way. It does its job perfectly. There’s nothing more to say.

The keyboard’s most striking feature is the red trackpoint, which all ThinkPads have. Some swear by it, others think it’s superfluous rubbish. Personally, I couldn’t care less about it. It is very rare that I use it. But when I use it, it does its job as it should. It responds precisely to input and is easy to control.

The keys respond very directly to input and offer a very pleasant typing experience. They could offer a little more resistance for my personal taste, but that’s grumbling at a high level. Even longer texts are easy to write with the ThinkPad keyboard and as long as you don’t use the one-finger hack system for typing, your colleagues will appreciate that the keyboard produces hardly any noise.

Below the number pad is the fingerprint reader and below it is the ThinkPad font, which all devices of this type have.

The back of the display is black with just a ThinkPad logo. It has an LED as an i-dot, which shows you whether the device is turned on or not. By the way, the lid is the only part of the case that is made of aluminium. It looks really chic, but unfortunately it is also a magnet for fingerprints.

The workmanship is top. There are no disturbing burrs or edges. All gaps are even. Only the display hinges are a bit too tight for my taste. I simply like it when I can open a notebook with one hand without it lifting off the table. But that is a marginal note. The advantage of the firm hinges is a firm display stand.


The ThinkPad E590 offers plenty of connections. As mentioned, they are on both sides. On the left side you find the USB-C port, which is also used for charging. Next to it is the HDMI port. Two USB-A ports follow, one of which is a power USB port. The 3.5mm combo connector is on the left side. Via the USB-C port you can connect the notebook to an external monitor and – if the monitor supports it – let it charge.

On the right side you’ll find the card reader, the USB A 2.0 port, the Ethernet port and the Kensington lock. Why a USB 2.0 port is still installed nowadays is not clear to me. The only really sensible use for this is a mouse. Basically, a USB-C port would have been better, though.

But in general, everything important is available. You can connect a monitor via HDMI. And if you need more connections, there are a number of docking stations, which extend the possibilities partly considerably.


Lenovo has given the ThinkPad E590 a matt Full HD display with IPS panel. Distracting reflections? Nothing. Size and resolution are well balanced. Your content is therefore displayed crisp and sharp. Thanks to the panel there are also large viewing angles, so that even lateral views of the display are no problem.

Colours look lively and natural without exaggerating. However, the ThinkPad E590 doesn’t offer too good color accuracy. Like all test devices, we calibrated it with the Spyder 5: 63% sRGB, 45% NTSC and 47% AdobeRGB coverage are not good values. However, they are also no exceptions. The HP Probook 450 G6 (test) and the MateBook D (test) with Ryzen CPU provide similar values.

The color space coverage is not a leg-breaker in everyday use. You should just be aware that this ThinkPad is not suitable for color critical work. For all other tasks the color values are sufficient.

Unfortunately, the ThinkPad E590’s display is not really bright. We measured an average of 219 cd/m². That is easily sufficient in closed rooms. You should look for a shady place outdoors, though, because contents are outshined relatively quickly in direct sunlight.

As you can see in the graphic above, the illumination is not even. But the deviations are still within an area that is not noticeable in everyday life. The only exception is the upper left corner, where the difference in brightness for dark content can be seen when looking closely.


The ThinkPad E590 comes with Windows 10 Pro 64-bit pre-installed. Unfortunately there is also bloatware on the system: Among them Candy Crush Saga and Candy Crush Friends.

McAfee also wants to persuade you to purchase a paid program. You can argue about Spotify, about Xing as well. If you don’t like the programs: you can uninstall them completely.

Lenovo Vantage is also installed. This is a hub that allows you to keep the ThinkPad drivers up to date. You also have all the important data at a glance, which could be important for support in case of doubt.

In delivery state, 209 GB of the 256 GB of the SSD are still available to you.


The ThinkPad gives you enough power for all the office tasks you encounter in everyday life. With PCIe SSD, all your data is loaded quickly.

And with Intel graphics built right in, you’ll have enough power to get your small tasks done in Photoshop without delay. For more complex tasks, the ThinkPad E590 will slow you down. But since the color space coverage is not very good, the point graphics editing is not very important.


With the battery, you don’t have to worry about running out of juice too quickly. The ThinkPad E590 lasted just under six and a half hours in everyday use. Thus, even longer trips without a power outlet can be easily bridged.

Noise / Temperature (Overheating)

In everyday life, you won’t hear the ThinkPad E590. It does its job quietly and unagitated. The fans are audible in the stress test. But only if you have a quiet environment. Keyboard noises drown them out without problems.

The temperature is also kept within limits. The case only heats up in front of the display in the hinge area. There the waste heat from the notebook is conducted. All other areas stay pleasantly cool. Inside, the CPU’s temperatures rose to a maximum of 73°.


Here Lenovo is exemplary. You only have to loosen nine screws to get to the ThinkPad E590’s inner workings. Then you have to use a fine screwdriver or a card to pry open the bottom part. It’s quite tight, but doesn’t have any barbs. Great: The screws can’t fall out of their holes.

After opening it, you have full access to the inside. You can immediately add a second RAM bar or upgrade to 32 GB RAM in general. The SSD can also be replaced very easily. And if the battery should weaken after some time, it can also be replaced easily.


The ThinkPad E590 offers average performance in terms of sound. As with all notebooks, the sound is high-fidelity and tends to get shrill at higher volumes. While the sound is flat at high volume, it offers a halfway balanced picture at medium volume. Middles are recognizable, depths partly also.

For the most common cases in everyday business life, such as video telephony, it is, however, suitable throughout. Voices are clear and don’t sound tinny.


The ThinkPad E590 offers you a lot of performance for your everyday work for the called price of currently almost 690 Euros. The built-in hardware is fixed and ensures that your data is loaded quickly and without delay. Thanks to the many ports you have many possibilities to connect peripherals.

The workmanship is excellent and the ThinkPad makes a very robust impression. It’s also easy to upgrade if you’re running out of hardware performance or the SSD is getting too small. Lenovo has done everything right here. There are only deductions for the slight weaknesses in the display.

Overall, the ThinkPad E590 is an absolutely recommendable notebook for the office with a good price-performance ratio.
