Lenovo IdeaPad 5 15ALC05 in review: 15.6-inch laptop convinces and surprises

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.
Marcus Schwarten, 👁 Sebastian Jentsch (translated by Stephanie Chamberlain), 🇩🇪 🇮🇹 ...

The Lenovo IdeaPad 5 15ALC05 is equipped with the AMD Ryzen 5 5500U including the AMD Radeon RX Vega 7 GPU. In addition, there's 16 GB of DDR4 SDRAM in dual-channel mode and 512 GB of SSD storage. As a result, its configuration is identical to that of the 14-inch IdeaPad 5 14ALC05 in many aspects. Our review of the IdeaPad 5 15ALC05 will clarify the remaining differences aside from the display diagonal size.

In addition, the review sample has to compete against other 15.6-inch rivals like the Lenovo ThinkPad L15 G2 with the AMD Ryzen 5 5600U, and the Acer Aspire 5 A515-56-511A with the Intel Core i5-1135G7.

Case: Classy and relatively light laptop made of aluminum

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.

Connectivity: The basics are on board

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.

SD card reader

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.

Communication

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.

Webcam

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.

Accessories

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.

Maintenance

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.

Warranty

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

Input devices: Large keys and narrow numpad

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.

Touchpad

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.

The display has almost no screen bleeding.

Lenovo installs an in-house manufactured 15.6-inch IPS panel with a Full HD (1920x1080 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.

* ... smaller is better

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.

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
18 ms ... rise ↗ and fall ↘ combined↗ 9 ms rise
↘ 9 ms fall
The screen shows good response rates in our tests, but may be too slow for competitive gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 25 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (23.8 ms).
       Response Time 50% Grey to 80% Grey
29 ms ... rise ↗ and fall ↘ combined↗ 13 ms rise
↘ 16 ms fall
The screen shows relatively slow response rates in our tests and may be too slow for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 636 (maximum) ms. » 23 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (37.7 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 not detected

In comparison: 52 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 17031 (minimum: 5 - maximum: 2500000) Hz was measured.

Performance: Laptop with enough power for everyday use

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.

Processor

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.

DPC latencies

The review sample performed solidly in our standardized DPC latencies test. Therefore, there shouldn't be any problems with real-time audio and the like, even if the measurements are naturally always only a momentary snapshot.

Storage

Lenovo 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.

Graphics card

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 integrated graphics unit operates at a maximum of 1,800 MHz. Up to 2 GB of RAM are allocated to the GPU by default, 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).

Gaming performance

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.

Noise emissions

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.
