Idea(l)Pad? The Lenovo IdeaPad 5 15ALC05 offers a powerful CPU/GPU combo and a large battery for less than 1,000 Euros (~$1,174), but it also surprises in the test with a few points of criticism compared to its 14-inch sister model. Our review reveals the exact strengths and weaknesses of the 15.6-inch laptop.

The design of the Lenovo IdeaPad 5 15ALC05 is simple and straightforward. The device comes in a gray-silver aluminum case, making a high-quality impression with the choice of materials alone, which can be confirmed in terms of feel as well. Only the display’s black plastic bezel spoils the picture a bit.

Workmanship leaves no room for criticism; all gap dimensions are as you would expect them to be. The very wide hinge is relatively stiff when opening and closing the lid. However, the display wobbles for quite a while.

Apart from the Honor MagicBook 15, the Lenovo IdeaPad 5 15ALC05 is the lightest of the 15.6-inch comparison models. It weighs around 1.7 kg. Together with the power adapter, a good 2 kg have to be transported when the laptop is taken along on the go.

The device doesn’t have to shy away from its rivals when it comes to size, either. Only the 14-inch Lenovo IdeaPad 5 14ALC05 is (as expected) noticeably smaller. Most 15.6-inchers measure a couple of millimeters or sometimes even centimeters more.

The Lenovo IdeaPad 5 15ALC05 offers the basic connectivity that you should expect in this price range. Three USB ports are distributed along the left and right sides.

There’s an HDMI output for an external monitor as well as DisplayPort via the single USB-C port. This is one of the points of criticism, because this port is also used for charging. In other words, no other USB-C device can be connected without resorting to accessories when the laptop is plugged in.

LAN, Thunderbolt, and Kensington are not included. However, there’s a card reader in return. Thanks to there being enough space between each other, all ports are easy to reach.

In combination with our 64 GB Toshiba Exceria Pro SDXC UHS-II reference memory card, the card reader can almost be described as a total failure. It’s the slowest in the test field. This is definitely surprising, since the 14-inch sister model together with the same Toshiba card reaches the best rates among the comparison models, showing that Toshiba knows how it’s done. The device is good for transferring a few photos. However, you should be prepared for unnecessarily long waiting times when transferring larger amounts of data.

The Lenovo IdeaPad 5 15ALC05 doesn’t really cut a fine figure in our Wi-Fi review in the test, either. It’s also ranked far behind here, but at least it still manages to achieve better rates than the average of the built-in Wi-Fi module from RealTek when sending data. The competitors that also offer the new Wi-Fi 6 / WLAN ax like the IdeaPad 5 14ALC05 does with the Intel Wi-Fi 6 AX200 or AX201, perform much better here.

Although the webcam only has the usual 720p resolution, it makes a much better impression in the test. It has the second-best average ∆E value in the comparison field after the Honor MagicBook 15, and it captures colors quite well as a result. Judging by the competition, there’s also little to complain about in terms of the HD camera, so nothing stands in the way of video calls and the like with the Lenovo IdeaPad 5 15ALC05.

It’s also practical that the camera can be blocked with a mechanical shutter. This should provide a better and safer feeling for certain users.

Apart from a power adapter, which has an adequate capacity of 65 watts, Lenovo doesn’t include any other accessories with the IdeaPad 5 15ALC05. The manufacturer offers optional accessories like docking stations in its online store. This can also help address the lack of USB-C ports.

Nine tiny Torx screws on the bottom block the access to the interior. However, there aren’t many upgrade options available inside due to the soldered RAM.

Lenovo offers the usual 24-month manufacturer’s warranty in Germany.

Keyboard
A 15.6-inch display diagonal and margins of only about 1.5 cm to the left and right of the base unit provide enough space for Lenovo to accommodate a sufficiently large keyboard along with a numpad squeezed next to it despite the relatively compact case. The latter differentiates the device from its smaller counterpart, the Lenovo IdeaPad 5 14ALC05.

The individual letter keys measure around 16 x 16 mm and are therefore about as large as on a standard PC keyboard. The F1 to F12 keys have the usual double assignments to adjust the display brightness or volume, but also to launch the calculator. In addition, there’s a two-stage backlight and a fingerprint sensor integrated into the elongated power button found at the far right above the numeric keypad.

Overall, the keyboard quickly provided a good and familiar typing experience in our test. The noise level is also kept within limits during typing. Even the space bar, which is often pretty rattly in many laptops, only gets louder in the Lenovo IdeaPad 5 15ALC05 when you hit it very emphatically.

At approximately 10.5 x 7 cm, the touchpad is adequately sized; it’s centered below the space bar and therefore slightly offset to the left side of the case. It makes a solid impression. Besides the fairly loud click noise, the right side of the non-separated click surfaces found on the bottom area produced a slightly creaking noise at times. However, this could also be a problem with our test device.

Lenovo installs an in-house manufactured 15.6-inch IPS panel with a Full HD (1920×1080 pixels) resolution in the IdeaPad 5 15ALC05. The display is non-reflective and matte, something that we’ll discuss in more detail below.

First, we want to take a look at the measurements that we determined in our review of the Lenovo IdeaPad 5 15ALC05.

There’s almost no screen bleeding. The panel scores better than the competition when it comes to response times. However, this isn’t that decisive in a “non-gaming laptop”. Otherwise, unfortunately, there are also several points of criticism. The display’s color-space coverage is very poor with 59% of sRGB and 38% of AdobeRGB. This isn’t good enough for users who want to do professional or semi-professional graphics editing or the like.

The display’s brightness is respectable with a maximum of 376 cd/m². However, it decreases quite significantly towards the edges, which leads to the worst brightness distribution rate. The Lenovo IdeaPad 5 15ALC05 also does poorly in the test and against the comparison models when it comes to black level, contrast, and color reproduction. In short: The Lenovo IdeaPad 5 15ALC05 has the worst display among the contenders compared here.

Thanks to the fairly good brightness of the panel as well as the matte display, the Lenovo IdeaPad 5 15ALC05 is also a good companion for outdoor use. And thanks to the IPS panel, the screen content can be viewed easily, even from very oblique viewing angles.

Display Response Timesℹ

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.

Screen Flickering / PWM (Pulse-Width Modulation)ℹ

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 not detectedIn comparison: 52 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 14759 (minimum: 5 – maximum: 2500000) Hz was measured.

The configuration of the Lenovo IdeaPad 5 15ALC05 that we’re reviewing (82LN0035GE) is equipped with the AMD Ryzen 5 5500U and the AMD Radeon RX Vega 7 graphics unit, as well as 16 GB of DDR4 SDRAM in dual-channel mode and a 512 GB SSD. Alternatively, Lenovo also offers the IdeaPad 5 in other configurations like with the same CPU/GPU combination and only 8 GB of RAM (82LN0034GE), for example.

Short information in advance: Lenovo offers three different energy profiles in its Vantage software. We mostly performed our benchmarks using the “Smart Cooling” mode. Compared to “High Performance”, no significant differences were found in the measured results.

The built-in AMD Ryzen 5 5500U is a hexa-core processor. Its base clock speed is 2.1 GHz, and it can operate at up to 4 GHz via Turbo. The CPU supports SMT/Hyper-Threading (12 threads), but it’s not based on the new and faster Zen 3 architecture like the Ryzen 5 5600U. Instead, both APUs are based on the Zen 2 architecture, which means less L3 cache among other factors.

As expected, the Lenovo IdeaPad 5 15ALC05 is on par with the Lenovo IdeaPad 5 14ALC05 that is equipped with the same processor in our CPU benchmarks. In the single-core benchmarks, they’re narrowly lagging behind the test field. In contrast, the Ryzen 5 5500U is able to show off its performance in the multi-core benchmarks, leaving the rivals with the Intel Core i5-1135G7 significantly behind.

As our stress test further below also shows, the CPU maintains its processing speed very steadily over time after an initial minor drop in the Cinebench R15 Multi endurance test, and it’s only marginally below the Lenovo ThinkPad L15 Gen 2 with the stronger AMD Ryzen 5 5600U.

Toshiba clearly didn’t do itself any favors by choosing the 512 GB M.2 SSD from Samsung. This unit differs from the storage device found in the 14-inch model and is clearly inferior to it as well as to all the other SSDs in the comparison models. However, this is only noticeable in everyday use at most when transferring particularly large amounts of data.

Lenovo hasn’t included a dedicated graphics solution in the IdeaPad 5 15ALC05, and it uses the AMD Radeon RX Vega 7’s graphics performance instead. The on-board graphics unit operates at a maximum of 1,800 MHz; it’s equipped with 2 GB of graphics memory, and it supports DirectX 12.

The test device ranks in the midfield when it comes to the graphics performance tests. However, it always performs above the average of all devices equipped with the AMD Radeon RX Vega 7, meaning that Lenovo manages to get a lot out of the GPU. In addition, the GPU maintains a constant operating speed over time even under load, albeit only at around 1,300 MHz.

When the device is loaded with graphics-intensive computations (e.g. gaming), you don’t even need to have a power outlet nearby. After all, with an overall score of 5,080 points when running 3DMark 11 on battery power, it performs less than 10% worse than when it’s plugged in (5,421 points).

Even though the Lenovo IdeaPad 5 15ALC05 is definitely not a gaming laptop, it can be used for the occasional gaming session at least. The only condition is that users don’t expect too much in terms of graphics quality. This is because the provided performance is only sufficient for smooth gaming when the lowest, or depending on the game, even medium or high graphics settings are selected.

Thanks to the fan, the Lenovo IdeaPad 5 15ALC05 is rarely truly silent. However, it’s barely audible in idle usage at 26 dB(A). Even during our stress test, although the fan operates continuously at high speed, it’s not intrusively loud at around 43 dB(A), and above all, its noise level is pleasantly uniform. We didn’t encounter any other unwanted noises in our test device. The Lenovo IdeaPad 5 15ALC05 isn’t really a quiet laptop, but it’s far from being annoying, either.

The Lenovo IdeaPad 5 15ALC05 barely warms up above room temperature when it’s under low load. In contrast, it reaches temperatures of just over 40 °C (~104 °F) under load. We measured the highest rates at the top, centered in front of the display. This shouldn’t come as a surprise, since the hot air is transported by the fan to the outside through the ventilation slots in the hinge’s area.

As a result, the laptop not only stays relatively cool under stress, but it can also be operated properly and without the risk of burns in any situation.

The Lenovo IdeaPad 5 15ALC05 in the stress test.The Lenovo IdeaPad 5 15ALC05 is surprisingly relaxed in the stress test. The CPU’s clock rate settles at a high 3,400 MHz and the GPU’s at just under 1,300 MHz. Temperatures remain constant with this performance at just over 75 °C (~167 °F). There’s no throttling to be noticed, which means that there are hardly any performance losses compared to the maximum performance, even when the hardware is under prolonged load. When running the 3DMark 11 benchmark right after the stress test, the laptop achieves identical rates compared to a cold boot.

The built-in stereo speakers of the Lenovo IdeaPad 5 15ALC05 are some of the best. Admittedly, like the speakers in most other laptops, they hardly have any bass, and they don’t get particularly loud. However, they reproduce mids and highs in a linear and quite balanced way. They’re good enough for reproducing the sound of a few video games, streaming movies, or listening to some music while working.

Surprisingly, the Lenovo IdeaPad 5 15ALC05 actually consumes less power than the almost identically equipped 14-inch model. This suggests that the panel is considerably more energy-efficient. Compared with the other competitors, the test device ranks in the midfield. It consumes a maximum of 52 watts, meaning that the 65-watt power adapter is absolutely adequate. In addition, the battery is recharged quickly thanks to fast charging.

Thanks to the low consumption and the very large 70 Wh battery, the Lenovo IdeaPad 5 15ALC05 is a true endurance runner. It can’t quite keep up with the LG Gram 14Z90P, which is the class leader. However, it’s certainly sufficient to beat the competing 15.6-inch devices in our comparison. In the Wi-Fi test, it sometimes lasts twice as long as the competition. Even its smaller 14-inch counterpart runs out of steam a good 3 hours earlier.

The Lenovo IdeaPad 5 15ALC05 is largely convincing in our test.

The device scores points especially with its large battery and long battery runtimes combined with its low consumption. The CPU and GPU perform in the test as one would expect, and in line with what was familiar from the somewhat smaller 14-inch sister model, the Lenovo IdeaPad 5 14ALC05.

Surprisingly, though, the 15-incher scores significantly worse than the 14-inch model in some respects. According to our measurements, it has the slower SSD, the worse display, and a weak card reader. This is somewhat surprising, and it reduces the otherwise good impression made by the Lenovo IdeaPad 5 15ALC05 in our test.

The single USB-C port is inconvenient because it’s occupied by the power adapter. However, the aforementioned rivals fail to do a better job anyway. Otherwise, the Lenovo IdeaPad 5 15ALC05 shows only a few weaknesses in the test and proves to be a more than solid laptop for office, streaming, browsing, etc. Even the occasional game can be played when the graphics requirements aren’t particularly high.

In short: A good all-rounder with a lot of endurance at a fair price that doesn’t need to fear the competition from the Acer Aspire 5 A515-56-511A and the Asus VivoBook S15 D533UA. The smaller Lenovo IdeaPad 5 14ALC05 as well as the two 15.6-inch laptops, the Lenovo ThinkPad L15 Gen 2 and the Honor MagicBook 15, scored only slightly better in our test.

At the time of writing, the Lenovo IdeaPad 5 15ALC05 seems to be mostly out of stock in the United States. Nevertheless, you can keep tabs on Amazon or newegg, for example, and see if the device pops up there.

I have been fascinated by technology for around 25 years – especially technology that makes life easier rather than more complicated. Mobile devices such as laptops, smartphones, tablets, and smartwatches are particularly close to my heart as is the booming subject of smart homes. I have been working in these areas for several years now as a news and reviews editor. I have been active with various websites, including the smart home blogs homee, Nuki, and siio, as well as tech portals such as Giga and TechRadar. I have been writing news and laptop reviews for Notebookcheck since 2020.

I’ve been fascinated with technology ever since I got my very first Android smartphone, which was quite a while ago. The power packed into such a small footprint still amazes me. Learning to program made my understanding of technology deeper, and at the same time, it expanded my interest to the area of desktop computers and laptops. All this led me to enjoy reading and watching reviews of new devices, and that’s how I stumbled upon Notebookcheck. I immediately found their reviews to be very comprehensive, and luckily, I’ve even had the chance of translating them since 2019. When it comes to the huge field of technology, I’m currently also interested in specializing in Java programming.
