Lenovo IdeaPad 5 16 2-in-1 (Gen 9, 16AHP9) review – Ryzen Power in a Flexible Form
How about a huge 16-inch transformer that looks like a normal laptop but you can easily fold it into tablet mode? Yep, the Lenovo IdeaPad 5 16 2-in-1 (Gen 9, 16AHP9) is significantly bigger than all other 2-in-1 machines we have tested recently, but it still has a 360-degree hinge. The device is powered by AMD Zen 4 Hawk Point-HS CPUs which comes with a hefty 45W power limit. To achieve a reasonable weight, Lenovo has hammered the upgradability to one SSD slot and a replaceable Wi-Fi 6 card.
The machine that we picked has the default 1200p IPS touchscreen. This one is okay for normal work but its colors ain’t that punchy. For sharper image quality and better color accuracy, the optional OLED variant with a 2048×1280 resolution is the way to go but it also bumps the price of the notebook.
The port selection is definitely a nice surprise. It offers a pair of Type-Cs and two regular Type-A connectors. Despite the transforming capabilities, it’s pretty cool that Lenovo has retained the full-sized keyboard with a NumPad. Also, the two 2W speakers are Dolby Audio optimized.

What’s in the box?
On the inside of the box, you’ll find a bunch of manuals and a 65W Type-C charger. Some devices like ours are bundled with an optional Lenovo Digital Pen 2.
Design and construction
The design of the Lenovo IdeaPad 5 16″ 2-in-1 (Gen 9, 16AHP9) isn’t that different compared to the non-2-in-1 version. The color options are called Cosmic blue and Luna grey. We got the former and its anodized finish doesn’t attract a lot of smudges but it’s not fingerprint-proof either.
The whole chassis feels solid which is nice to see. The combination of a heavy lid and stable but stiff hinges means that you have to use both hands to open the notebook. The iterations with an IPS display are heavier (2 kilos) than the OLED models (1.9 kg). The profile height is the same for the two variants – 18.4 mm.
The bottom bezel is a bit thick-ish but the other three are thin. The lid is aluminum while the base is made of a mix of plastic and glass fiber.
The protrusion on the top is home to a 1080p Web camera with a privacy shutter. Sadly, face recognition isn’t available even as an option.
Because of the fancy hinge design, you can use this notebook in a standard clamshell form, tablet, tent, or stand mode.
The long speaker grill is positioned on top of the backlit keyboard with a NumPad and an AI hotkey that summons MS Copilot. The large keys offer above-average travel and nice clicky feedback. The typists out there should be happy. The fingerprint reader can be seen on the right palm rest.
The touchpad is slightly offset to the left. It’s kind of small (75 x 120 mm) given the big main body of the laptop. The Mylar surface of the pad ain’t that smooth but the accuracy is on point.
The bottom plate looks pretty normal for a Lenovo device of this caliber. It houses a 2-row ventilation grill, three rubber feet, and a Novo button hole. The heat is being exhausted through a vent on the rear that aims at the hinge cover. That’s why some amount of hot air makes its way to the display when the processor is fully stressed.
Ports
On the left, we can spot an HDMI 1.4b for up to 4k@30Hz external displays, two 10 Gbps USB Type-C 3.2 (Gen. 2) ports with PowerDelivery 3.1 and DisplayPort 1.4 capabilities, and a 3.5 mm Audio combo jack. On the right, there is a pair of 5 Gbps USB Type-A 3.2 (Gen. 1) ports (the formers sport an Always On extra), a microSD card reader, and a Power button.

Color Coverage
The whole “sail-shaped” map below (Fig. 1) consists of all the colors we can see, while the black crooked line shows all the colors from real-world scenes and nature around us.
Then, we’ve drawn some of the most important and interesting color spaces, compared to the colors the panel of Lenovo IdeaPad 5 16″ 2-in-1 (Gen 9, 16AHP9) can show:
Standard/For Web: sRGB – widely used color space for most consumer devices, ideal for Web design and development
For Print: AdobeRGB – used in professional photo editing, graphic design, and print
For Photographers/Video Editors: DCI-P3 – used in high-end film production, post-production, and digital cinema
Premium HDR: Rec.2020 – the widest consumer ITU color standard, covering a massive 75.8% of the visible spectrum, a benchmark for premium HDR content
Lenovo IdeaPad 5 16″ 2-in-1 (Gen 9, 16AHP9): the yellow dashed triangle (– – – – – –) represents the range of colors this monitor can display.
In our tests, we calculated the total color coverage of the monitor at 49% of the sRGB color gamut and 39% of the DCI-P3 color gamut.
(Fig.1) Lenovo IdeaPad 5 16″ 2-in-1 (Gen 9, 16AHP9) covers 49% of the sRGB gamut
Brightness and Contrast
The maximum brightness in SDR mode is 334 cd/m² in the center of the screen and 309 cd/m² averaged across the surface with a maximum deviation of 14%.
The Correlated Color Temperature (CCT) on a white screen at maximum brightness is 6100K.
The contrast ratio is 1120:1.
Uniformity: Luminance, Contrast, and Color Deviation
The figure below shows the results from our uniformity test across different sections of the screen. It’s measured at 179 nits (Windows slider = 74%) — a brightness level we consider typical for standard working conditions.
DeltaE values below 4.0 are acceptable for regular users. For those working with colors, screens with DeltaE values no higher than 2.0 are recommended.
Color Accuracy
Let’s check the difference between real colors and those you’ll see on the Lenovo IdeaPad 5 16″ 2-in-1 (Gen 9, 16AHP9). We measure that distance in DeltaE – the higher the number, the more different they look.
Values below 4.0 are acceptable for regular users, while values below 2.0 are suitable for color-sensitive work. A value below 1.0 means the difference is indistinguishable to the naked eye.
For the next graph, we’ve selected 24 common colors, including dark/light skin, blue sky, green grass, etc.
Before our calibration of the Lenovo IdeaPad 5 16″ 2-in-1 (Gen 9, 16AHP9), the Average color accuracy was 7.1 dE (Fig. 2), and with our Design and Office profile, it lowered to 4.5 dE (Fig. 3).
Comparison in the sRGB color space.
Here’s an illustration of what the Design and Office profile aims to deliver:

Visibility in dark scenes
Have you ever watched a movie with dark scenes where you could barely see anything? This often happens because many display panels struggle to differentiate the darkest nuances, making them appear the same.
The next figure illustrates how well the display reproduces these dark nuances. The left side of the image shows the display with stock settings, and the right side shows it with our Gaming and movies profile activated.
On the horizontal axis are the grayscale levels, and on the vertical axis – the corresponding display brightness.
You can also check how your display handles the darkest nuances but keep in mind that this also depends on the settings of your current display and the surrounding light conditions.
Response time (Gaming capabilities)
We test the reaction time of the pixels with the usual “black-to-white” and “white-to-black” method from 10% to 90% and vice versa.
We recorded Fall Time + Rise Time = 17.4 ms. Short pixel response time is a prerequisite for a smooth picture in dynamic scenes.
After that, we test the reaction time of the pixels with the usual “Gray-to-Gray” method from 50% White to 80% White and vice versa between 10% and 90% of the amplitude.
Health Impact: PWM (Screen flickering)
Some use PWM to regulate their brightness, which means that instead of reducing the light intensity, they pulse or flicker. Our brain merges the image, so it appears darker, but this strains both it and our vision, especially when the frequency of the pulses is low. You can read more about that in our dedicated article on PWM.
In the graph below, you see the intensity of light at different brightness levels—on the vertical axis is the brightness of the emitted light, and on the horizontal axis—time.
The light from the backlight of the Lenovo IdeaPad 5 16″ 2-in-1 (Gen 9, 16AHP9) display is not pulse-width modulated, providing visual comfort in the discussed aspect.
Health Impact: Blue light emissions
Installing our Health-Guard profile not only eliminates harmful PWM when the laptop uses it to control brightness but also reduces harmful Blue Light emissions while keeping the colors of the screen perceptually accurate.
If you’re not familiar with the Blue light, the TL;DR version is – emissions that negatively affect your eyes, skin, and your whole body. You can find more information about that in our dedicated article on Blue Light.
Health Impact: Screen Reflectance
Glossy-coated displays can cause eye fatigue in high ambient light conditions due to reflections. We measure the level of screen reflection with the display turned off, at a 60° angle.
The reflectance of the Lenovo IdeaPad 5’s screen is 104 GU.
High Gloss: >70 GU
Medium Gloss: 30 – 70 GU
Low Gloss: <30 GU

The IdeaPad 5 16″ 2-in-1, with its Ryzen 7 8845HS, offers comparable clocks no matter the load compared to its non-transforming sibling, which we have tested with the same CPU. Still, in long stress, the frequency is 300 MHz down than the official AMD base clock for this chip but this is more or less expected for a non-gaming device with a single-fan cooling.
Comfort during full load
If the processor is pushed to its limits, the fan emits a moderate amount of noise. In this case, the keyboard feels a bit warm on its upper side but nothing to worry about.
The “Auto” mode clocks are not that high but still fine for normal work. In addition, the noise is lowered.
Battery
Now, we conduct the battery tests with the Windows Best Power Efficiency setting turned on, screen brightness adjusted to 180 nits and all other programs turned off except for the one we are testing the notebook with. The 57Wh battery pack lasts for around 12 hours and a half of video playback. Оur test was conducted with the “Energy Saver” preset activated in the Windows “Power & Battery” menu and the “Battery Saver” mode selected in the Lenovo Vantage app.
Brightness: 180 nits; Display Mode: SDR
Time to Full Discharge: Higher is Better


Disassembly, Upgrade options, and Maintenance
To open this 16-inch transformer, you have to undo seven Torx-head screws. Pop the zones behind the hinges with a thin plastic tool and do the same for the top edges. Fully pry the back and the sides, the front should be last.
Here’s how the bottom plate looks on the inside.
The battery is a 57Wh model. To detach it, pull the connector towards the unit and undo the three Phillips-head screws that hold the unit in place. The capacity is enough for around 12 hours and a half of video playback.
The memory is soldered. All machines of this Lenovo series are configured with 16GB LPDDR5x-6400MHz RAM in dual-channel mode.
At least the Wi-Fi 6 card is upgradable.
The storage upgradability is limited to just one M.2 slot for 2242 Gen 4 NVMe drives. The SSD here is additionally cooled by a thermal pad from below.
The thermal system seems okay for a machine that lacks a dGPU. It has one fan, two long heat pipes, a decently-sized top-mounted heat sink, and a heat spreader.
Verdict
We are positively surprised by the fact that the Lenovo IdeaPad 5 16 2-in-1 (Gen 9, 16AHP9) nears the power of its non-2-in-1 version. Here, the performance of the Ryzen 7 8845HS will not top any benchmark charts but it’s more than sufficient for work and even for heavier tasks such as 3D rendering. In addition, the Radeon 780M still packs a punch scoring 120FPS in CS2 on Medium details.
The base 1200p IPS display (LEN160WUM (LEN9156)) is just fine for normal office tasks. It’s a PWM-free touchscreen with wide viewing angles and a good max brightness of 334 nits. Still, the color coverage isn’t one of its strengths. If that is important for you, the optional OLED model should be better in this regard, but it’ll cost you more money.
The Lenovo IdeaPad 5 16 2-in-1 boasts strong build quality, many USB ports, long battery life, and capable input devices.
