Lenovo Ideapad L340-17API in review: 17.3 incher pleases with good battery life. Lenovo supplies a simple notebook with the Ideapad L340, which can score with a strong Ryzen 5-3500U-APU, a solid state disk, good battery runtimes and a thoroughly good keyboard. But unfortunately, the 17 incher is weak: Bad TN-panel, lame RAM and missing memory card reader.
The Ideapad L340-17 series follows the Ideapad 330-17 series. The devices of both series are very similar, but there are differences in detail.
The Ideapad L340-17API model we have before us is powered by a Ryzen-5-3500U-APU from AMD. Alternatively, models that rely on Intel processors are also available. Competitors include devices like the Asus VivoBook 17 X705UA, the Dell Inspiron 17 3780, the HP 17.
Design & Ports / Interfaces
The case of the Ideapad L340 is made of silver-gray (“Platinum Grey”) plastic throughout. The display frame is coloured black. The base unit’s upper side and the lid’s back are kept in a brushed metal look.
There’s nothing to criticize on the manufacturing side. The gaps are correct, and sharp edges aren’t noticeable. There is room for improvement in terms of stability: the base unit and lid can be twisted a bit too much for our taste.
Our test device doesn’t have an optical drive to offer. There is a dummy in the drive bay. However, the SATA slot necessary for connecting an optical drive is present. Thus, a corresponding drive could be retrofitted if necessary.
The L340 doesn’t have a maintenance cover. In order to get to the innards, the lower shell must be removed. First of all, the dummy, which is located in the slot for the optical drive, has to be removed. Then all screws on the bottom of the unit are removed.
Afterwards the lower shell can be removed with the help of a thin spatula or a joint smoother. Care must be taken when doing this. The lower shell is held by many clips. Now you have access to the solid state disk, the fan, the WiFi module, the RAM module and the battery.
The interface offer turns out clearly arranged. The computer comes with two type A USB slots and one type C USB slot, which all work according to the USB 3.2 Gen 1 standard.
An HDMI output and a Gigabit Ethernet connection are also included. The Ideapad does not have a memory card reader on board. All ports are placed in the back of the notebook’s left side. Thus, the areas next to both sides of the wrist-rest remain free of cables.
The WiFi module carries a chip (QCA9377) from Qualcomm. Besides the WiFi standards 802.11a/b/g/n, this also supports the fast ac standard. The transmission speeds determined by us under optimal conditions (no other WiFi devices in the immediate vicinity, short distance between notebook and server PC) turn out to be average.
Competitors provide similar values. Wired network connections are handled by a Gigabit Ethernet controller from Realtek’s RTL8168/8111 family. This controller performs its tasks smoothly.
Keyboard & Touchpad
Lenovo equips the Ideapad L340 with an backlit chiclet keyboard that includes a number pad. The flat, slightly roughened keys have a short stroke and a clear pressure point. W
e like the key resistance. The keyboard yields a bit during typing. This hasn’t proven to be annoying. All in all, Lenovo supplies a thoroughly good keyboard here, which is also suitable for doing regular typing work.
The multi-touch capable clickpad occupies an area of about 10.5 x 7 cm. Thus, a lot of space is available for using the gesture control. The smooth pad surface makes it easy for fingers to glide. The pad also reacts to input in the corners. It has a short stroke and a clear pressure point.
The Ideapad’s matt 17.3-inch display works with a native resolution of 1,600 x 900 pixels. Brightness (200.6 cd/m²) and contrast (500:1) are not convincing.
We consider rates beyond 300 cd/m² or 1000:1 as good. Within our field of comparison, the HP 17 and Dell Inspiron 17’s screens meet our requirements. Positive: The L340’s screen never shows PWM flickering at any time.
The screen’s color display isn’t very impressive either. With a DeltaE 2000 color deviation of 10.36, the target range (DeltaE less than 3) is far away. Furthermore, the display suffers from a clear blue cast.
The colour representation of the screen can be slightly improved by using the colour profile provided by us. It is important to make sure that the same display model (manufacturer + model number) is used as in our test device. Otherwise the colour representation can deteriorate even further. Within a notebook model series, screens from different manufacturers are often used.
Lenovo equips the Ideapad with a viewing angle unstable TN panel. Thus, the screen can’t be read from every position. The notebook can hardly or not at all be read outdoors due to the display’s low luminosity.
Lenovo has a 17.3-inch notebook in its range with the Ideapad L340-17API, which offers enough computing power for office and internet applications.
The integrated GPU allows the use of one or the other game. You’ll have to pay about $750 for our test device. Other equipment variants are available.
The Ideapad is powered by a brand new Ryzen-5-3500U (Picasso) CPU from AMD, which offers more than enough computing power for office and internet applications.
The CPU part of the APU consists of a quad-core processor that operates at a basic speed of 2.1 GHz. By means of Turbo an increase up to 3.7 GHz is possible. The processor supports simultaneous multithreading (two threads can be processed per core).
The multi-threaded tests of the Cinebench benchmarks are run for a short time at 3.3 to 3.4 GHz. Then the clock rate drops to 3 to 3.1 GHz.
The single-thread tests are processed at 1.5 to 3.7 GHz. In battery mode, the multi-thread tests are processed initially at 2.4 GHz, then at 3.1 to 3.2 GHz. The single-thread tests are processed at 1.4 to 2.4 GHz.
We check whether the turbo is also permanently used in network operation by running the Cinebench R15 benchmark’s multi-thread test in a continuous loop for at least 30 minutes. The CPU can maintain a turbo speed of 3 to 3.1 GHz for a few minutes, then the clock rate drops to 2.9 GHz and remains at this level for the rest of the test.
The Ideapad delivers better results than most notebooks equipped with the direct predecessor APU – Ryzen 5 2500U. The improvements made by AMD to the Zen+ architecture of the 3500U APU (smaller structure width, minimally higher operating speeds, slightly more power per clock) thus seem to be bearing fruit.
The system is fast and fluid. We have not encountered any problems. The notebook has more than enough computing power for office and internet applications. Good results in the PC-Mark benchmarks add to this.
However, Lenovo leaves a part of the performance idle because the RAM runs in single channel mode. The dual channel mode can’t be activated afterwards because the computer only has one RAM bank.
There are, however, also equipment variants of the Ideapad L340 available in which the dual channel mode can be used. These models are additionally equipped with 4 GB of soldered memory.
A SATA SSD from Samsung is used as system drive. This is a model in 2.5-inch format that offers 256 GB of storage space. Approximately 213 GB of this can be used in the delivery state. The remaining storage space is divided between the recovery partition and the Windows installation. The SSD delivers good transfer rates overall.
There is still an unoccupied M.2-2280 slot inside the computer. This can accommodate NVMe SSDs.
AMD’s integrated Radeon RX Vega-8 graphics core is responsible for the graphics output. The GPU supports DirectX 12 and operates at speeds of up to 1,200 MHz.
The results in the 3D Mark benchmarks are at a normal level for this GPU. Since the dual channel mode is closed to our test device, no performance increase is possible.
The L340’s hardware brings quite a lot of the games in our database smoothly onto the screen. This is especially true for games that have been around for a few years or that don’t have high hardware requirements, such as Diablo 3, Team Fortress 2 and League of Legends.
The games achieve smooth refresh rates in HD resolution and low to medium quality settings. The titles of the years 2018/2019 can hardly be used. Isolated games achieve playable frame rates at low resolutions and low quality settings.
Noise & Temperature Levels
The Lenovo notebook doesn’t make excessive noise. When idle, the fan often stops and then there is silence. It doesn’t turn up too much under load. So we measured a sound pressure level of 35.3 dB(A) during the stress test. Unfortunately, the fan emits a quiet whistling sound.
The Lenovo laptop passes our stress test (Prime95 and Furmark run for at least an hour) in the same way in mains and battery mode. The processor works at 2.5 GHz at the beginning of the test. After about 10 minutes the clock rate drops minimally to 2.3 to 2.4 GHz and remains at this level.
The GPU’s operating speed drops from 900 MHz to 600 MHz during the same period. The stress test represents an extreme scenario that does not occur in everyday life. We use this test to check if the system runs stable even under full load.
The notebook doesn’t heat up excessively. During the stress test, we only registered temperatures above 40 degrees Celsius on two measurement points on the bottom. The rates are in the green range in everyday use.
The stereo speakers have found their place on the bottom of the device. They produce a somewhat muffled sound that lacks bass.
The maximum volume is also quite low. For a better sound experience, headphones or external speakers should be used.
Our practical WiFi test simulates the load when calling up web pages. The “balanced” profile is active, the energy saving functions are deactivated and the display brightness is regulated to about 150 cd/m².
The Ideapad reaches a runtime of 6:54 h. Although Lenovo only gives the L340 a relatively small-capacity battery (36 Wh), the device gets a lot of battery life out of the battery.
Lenovo’s 17.3-inch notebook is powered by a Ryzen 5-3500U APU, which provides more than enough processing power for office and Internet applications.
In addition, it allows the use of computer games, at least to a limited extent. However, the APU can’t fully unfold because the RAM only runs in single channel mode; it is not possible to activate dual channel mode.
Lenovo supplies a 17.3 inch notebook for the home desk with the Ideapad L340-17API. However, the configuration variant we have at hand has serious weaknesses.
A solid state disk in 2.5 inch format provides for a fast running system. There is also a slot for an NVMe-SSD in M.2-2280 format inside the computer. In order to install a corresponding SSD, the case would have to be opened. The computer doesn’t have a maintenance flap.
The matt HD+ screen doesn’t arouse any enthusiasm. It’s dark, low-contrast and unstable viewing angle. Moreover, the color display isn’t convincing either. The calculator’s keyboard has left a good impression and is also suitable for doing regular typing work.
However, we miss a key illumination. The good battery runtimes that Lenovo gets out of the relatively small-capacity battery shouldn’t remain unmentioned. Unfortunately, the fan produces a quiet whistling noise.
We basically liked the Ideapad L340-17API; however, we can’t recommend the configuration variant in front of us for purchase. The two major weak points are the dark, low-contrast, viewing angle-unstable TN screen and the RAM running in single channel mode.
The Ideapad’s equipment variants, which have a somewhat stronger APU, a viewing angle stable IPS full HD display, as well as RAM running in dual channel mode on board, are available for just $50 more.
All in all the Lenovo Ideapad L340 is ranking first versus Ideapad C340 due to the better overall performance and hardware.
Ranking Second: Lenovo Ideapad C340
- Good Performance
- Cheaper price than Ideapad L340
- Fast SSD Storage
- Battery life could be better
Small, light and flexible. The IdeaPad C340 scores with a very fast SSD in addition to a good workmanship. The built-in hardware offers you enough power for all everyday tasks and it is light enough that you can take it with you everywhere.
The IdeaPad C340 leaves a good impression overall in the test. It completes all tasks set without any problems. Merely the display showed weaknesses. But before I tell you the details, here are the technical data at a glance.
Design & Ports
The IdeaPad C340 comes along with a pretty classic design. The display bezels look a bit old-fashioned, as they are relatively wide for today’s conditions.
This applies especially to the lower frame. Lenovo has placed the webcam in the upper frame. You can cover the camera with a small slider if you really want to make sure that nobody is watching you.
The keyboard is located in a small recess so that it won’t be damaged if you use the IdeaPad C340 in stand-up mode. You have to do without spacers that protect the surface from direct table contact.
The case is mostly made of aluminum. Only the bottom is made of plastic.
The keyboard comes without a numpad and offers a three-level backlight. Because the keys offer relatively little resistance, typing is easy and quiet. The fingerprint reader is located on the right in front of the keyboard.
The IdeaPad C340 has a large and centrally placed touchpad. Inputs are quickly and easily recognized. There are still two mouse substitute keys at the bottom of the touchpad.
The processing is flawless. There are no burrs or sharp edges and the gaps are all even.
The connections are distributed on both sides of the IdeaPad C340. On the left side you’ll find the 3.5 mm jack, the USB-C port, the HDMI port and the socket for the power connection.
On the right side behind the power button you find the card reader and the two USB-A connectors. The IdeaPad doesn’t have a LAN port. If you want to have one, you’ll have to get a docking station.
The display is definitely not a highlight. It is a glossy IPS touch display with Full HD resolution. Your touch inputs are recognized quickly and precisely. However, if you use the IdeaPad C340 as a normal notebook, you shouldn’t press too hard. The display wobbles for a relatively long time.
The C340 can’t score in terms of color space coverage. With 66% sRGB, 47% NTSC and 49% AdobeRGB color space coverage, it blends in at the lower end of the office notebooks in our database. The rates are completely okay for working with Office, and film consumption is also no problem.
However, you should not do any image editing with it. To be fair, one has to say that similar notebooks didn’t stain themselves with glory when it comes to color space coverage either.
Unfortunately, the IdeaPad C340 also weakens in terms of brightness. We measured an average of 182 cd/m². This is sufficient indoors, as long as you don’t have direct light irradiation.
If you want to use the Convertible outdoors, you should look for a place where you won’t sit in the sun. The display will soon reach its limits and the contents will be outshined by ambient light.
The contrast is fine with 980:1. It is not outstanding, but more than useful for the purpose of the convertible.
Windows 10 Home 64 Bit is used as the operating system. Unfortunately, the apparently unavoidable Bloatware is also found here. Namely Candy Crush Saga and Friends, but also Xing.
If you don’t need the stuff: They can be completely uninstalled. And then there’s McAfee, who wants to convince you to buy the paid full version more or less unobtrusively.
Lenovo Vantage, on the other hand, is a useful program that allows you to keep your system up to date with little effort.
On the 256 GB SSD, 205 GB are still free on delivery.
The built-in hardware clearly identifies it as a notebook for the office area. In comparison with similarly configured notebooks, it can really score points. Applications are loaded quickly and run smoothly. Even switching between different programs is smooth.
The SSD comes from Samsung and is really fast. It achieves read rates of 3422 MB/s in the benchmark. The value drops to 556 MB/s when writing. But this is a completely sufficient rate for everyday use.
The limits of the built-in UHD graphic 620 show up in graphics-heavy tasks. The rates make it clear that light browser games are no problem. Everything that really requires graphics should be avoided on this device.
Lenovo states the battery life with up to eight hours. Manufacturer values should always be taken with caution and that’s why we tested ourselves.
It didn’t quite last four hours at full brightness with just under 200 cd/m². If you turn the brightness down, you’ll of course get longer. But since the display isn’t the brightest, the question arises how useful this is.
Noise & Temperature Levels
In normal everyday life you will only hear the IdeaPad C340 in the rarest of cases. Every now and then the fans start up, but the noise level stays at a low level. The C340 also remained relatively quiet in the stress test.
The temperatures stay in the green range in the stress test. After a peak of 96°C at the beginning, the cooling system comes into play. The Core i5-8265U’s temperature then levelled off at 79°C on average. This value is not critical and you shouldn’t have any problems in everyday life.
If that’s what you want, you can open the IdeaPad C340 pretty easily. You only have to loosen ten small screws on the bottom. The base plate is anchored in the case with several small lugs.
But they can be easily removed. To do this, you should start by lifting the plate at the hinges. To release it from its anchoring, it is enough to slowly walk around the device with your fingernails or a plastic card and carefully pull the plate up.
Inside you have access to all important parts. The SSD is right in front of you. To change the RAM, you have to remove the silver cover in the middle. One of the RAM’s two latches is occupied. 4 GB are soldered. A maximum of 16 GB RAM can be installed here.
You can also change the battery if you feel like it. Thankfully it is only screwed and not glued. So Lenovo does everything right here.
Notebooks and sound are generally not the best of friends. But the IdeaPad C340 stands out from the crowd. The sound is balanced at half volume.
Surprisingly, the highs aren’t dominant, but are in a good proportion to the midrange and bass. Of course, you can’t expect real basses here. But the lows are there.
If you turn up the volume to the maximum, the sound remains balanced. Shrill highs stay out. The price for this, however, is that the Convertible doesn’t get very loud. You can’t fill a party with it. But for cosy movie nights on the couch the volume is sufficient.
Lenovo does a lot right with the IdeaPad C340. It’s robust, high-quality workmanship and Lenovo doesn’t save in the wrong place in terms of hardware. The battery life is no revelation. But it is easily enough to take a longer trip without having to worry that you won’t have any juice after a few minutes.
Only the display wasn’t completely convincing in the test, which is why the Lenovo Ideapad C340 is ranking behind vs Ideapad L340. Though we also have to mention that the price is cheaper with the Ideapad C340.
For currently $500 you get an overall coherent package that you can easily expand if necessary.
