Lenovo IdeaPad Slim 5 14 laptop review: A successful allrounder with an OLED display
Users looking for a versatile, slim and lightweight laptop that offers decent power may well be happy with the IdeaPad Slim 5 14IMH9. For around US$1,000, the 14-inch device features a Core Ultra 5 125H, 16 GB LPDDR5x-7467 RAM (not expandable) and a 512-GB NVMe SSD. As a screen, the laptop uses a reflective 60-Hz 16:10 OLED display (1,920 x 1,200 pixels) which covers DCI-P3 in its entirety. Its Windows 11 Home operating system rounds out the package.
The IdeaPad Slim 5's competitors include other 14-inch laptops with Meteor-Lake CPUs, such as the Asus ZenBook 14, the HP Spectre x360 or the Yoga Pro 7 from the same manufacturer, of which we already tested an AMD variant.

Case
The laptop's case looks pretty good. Beginning with its sleek design and compact footprint—although the competition offers similar values in these areas. Its moderate weight of 1.4 kg gives you no reason to complain, either, meaning you can still comfortably carry the 14-inch device about with you. Apart from some small details, its stability and build quality are good, too.
Its hinge is neither too loose nor too stiff; it is possible to open the device with one hand, although the base unit does tend to sometimes swing a little in doing so. Thanks to its relatively light color, fingerprint marks can hardly be seen. Its maximum opening angle is 160°.
Connectivity
Ports
There is still room for improvement when it comes to the device's ports. Although the 14-inch laptop features a total of four USB ports, even its two Type-C ports are only compliant with the 3.2 Gen 1 standard—although they do support DisplayPort 1.4 and Power Delivery 3.0. There is also an audio jack, an outdated HDMI 1.4b port and a microSD card reader. As the ports are located in the back half of the two side panels, so an external mouse can be used without (space) difficulties.
SD card reader
The aforementioned card reader achieved a solid performance of just under 90 MB/s for sequential reading during our test.

Communication
The laptop showed no surprises when it came to its WLAN performance, either. A metre away from our reference router, the installed Intel module (Wi-Fi 6E AX211) delivered pretty good values which oftentimes resembled those of its competitors.
Webcam
Its webcam quality lies just above the—unfortunately miserable—laptop standard. The 2-MP model looks sharper than a lot of the competition, although it fails to deliver good color accuracy, as usual.
Accessories
Lenovo delivers the laptop alongside a few information manuals and a compact 65-watt power supply (USB C).
Maintenance
Its maintenance options strongly resemble those of the Yoga Pro 7. This means its bottom plate is held on by 6 Torx screws and several brackets. In contrast to its 14-inch brother, Lenovo hasn't implemented a dual-fan cooling unit—instead, it relies on one relatively large fan. The WLAN module and SSD are covered by a film. Unfortunately, the RAM is soldered on.
Warranty
The laptop is covered by a standard 12-month warranty.
Input devices
Keyboard
The same as on the Yoga Pro 7, the IdeaPad Slim 5's input devices are worthy of praise. Its keyboard boasts a good layout (apart from the small middle arrow keys) and the keys have a good size. It also feels better to type on this keyboard compared to most other manufacturers, although its key noise is quite loud for a classic rubber-dome model. Nighttime writing sessions are no problem thanks to its installed white backlighting.
Touchpad
Its touchpad is good, too—if you ignore the slightly rattly-sounding click areas. A size of 12 x 7.5 cm is respectable for a 14-inch device. In our test, it never had any issues with precision or gesture support. Its surface is quite smooth, meaning your fingers glide over it nicely.
Display
When it comes to OLED displays, tastes differ. If you want to spend a lot of time using your laptop in bright rooms or outdoors, then you would be better off looking for a device with a matte finish. Our test configuration's glare surface often causes very strong and unpleasant reflections.

* ... smaller is better
Apart from this, the OLED screen is mostly a success. Thanks to its incredibly low black value (practically 0 cd/m²), the Slim 5 delivers amazing contrasts that conventional IPS panels can only dream of. Its viewing angles are impressive, too.
The same can be said for its response times, which even demanding users should be pleased with. Further highlights include its generous color space coverage (about 100 % of DCI-P3 and AdobeRGB) and its generally high color accuracy straight out of the box.
Sacrifices may have to be made by people with eye problems. As is typical for OLED, the screen flickers at a relatively low frequency.

The screen shows very fast response rates in our tests and should be very well suited for fast-paced gaming. In comparison, all tested devices range from 0.2 (minimum) to 636 (maximum) ms. » 3 % of all devices are better. This means that the measured response time is better than the average of all tested devices (33.7 ms). |
Screen Flickering / PWM (Pulse-Width Modulation)
Screen flickering / PWM detected | 240 Hz | ||
The display backlight flickers at 240 Hz (worst case, e.g., utilizing PWM) . The frequency of 240 Hz is relatively low, so sensitive users will likely notice flickering and experience eyestrain at the stated brightness setting and below. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 17903 (minimum: 5 - maximum: 3846000) Hz was measured. |
Performance
The IdeaPad Slim 5 is a mid-range laptop. Users should carefully decide beforehand whether 16 GB RAM is enough in the long run, as it—as previously critiqued—cannot be swapped out. Its M.2 SSD (which is also only a 2242 model) could technically be swapped out for a larger 2280 model.
Testing conditions
There are three energy and performance modes hidden within the Lenovo Vantage software, ranging from battery-saving to maximum performance. Our measurements were all carried out with the intelligent cooling mode.
Witcher 3 (FHD/Ultra) | Battery-saving mode | Intelligente cooling | Maximum performance |
Noise | 33 dB(A) | 40 dB(A) | 42 dB(A) |
Performance | 14-24 fps | 26 fps | 26 fps |
Processor
The Core Ultra 5 125H is the cheaper brother of the Core Ultra 7 155H within the Yoga 7 Pro and it can handle 18 parallel threads instead of 22. Its clock rate and cache (18 vs 24 MB) are also slightly lower. Even so, the Ultra 5 125H did quite well in our benchmark tests. Although this wasn't enough for it to reach the level of the Yoga Pro 7, other laptops based on 155H, such as the ZenBook 14 or the Spectre x360, couldn't outperform it in the Cinebench loop.

The laptop's storage device doesn't work totally optimally. According to our Loop test, longer periods of load lead to temporary drops in speed. In general, the M.2 drive made by SK Hynix offers more than decent performance which will likely be sufficient for most users.

Graphics card
The iGPU integrated into the Core Ultra 5 125H is called Arc 7 and compared to the Arc 8, it features 112 instead of 128 Xe Vector Engines and 7 instead of 8 ray-tracing units/samplers—this isn't a terribly large reduction. Unsurprisingly, the IdeadPad Slim 5 was able to keep up well with devices based on the Ultra 7 155H and (at least in the synthetic graphics benchmarks) it came just ahead of the Radeon 780M within the Yoga Pro 7. If you want to play games occasionally, then you might still be better off with the Arc 8, as a few games we tested suffered crashes more than others (with identical drivers)—at least when using higher settings but even so, the games wouldn't have been playable then, anyway.

Gaming performance
As long as you don't overdo it with the resolution (maximum Full HD) and are satisfied with low to medium settings, the Arc 7 is also suitable for certain modern games. Things get tight when trying to run extremely demanding and/or moderately optimized games such as Alan Wake 2, Starfield, Lords of The Fallen, Avatar Frontiers of Pandora and Enshrouded. Here, you will inevitably have to use lower resolutions within the HD range or upscaling in the form of Intel's XeSS (if games support this). If you compare its gaming performance with the Yoga Pro 7, the Radeon 780M is around 10% faster on average, while the Arc 8 is almost 20% faster.

A positive: During our long-term test using The Witcher 3 (approx. 1 hour @ FHD/Ultra), its frame rate remained nice and stable. The Asus ZenBook 14 and the HP Spectre x360, on the other hand, showed enormous fluctuations.

Emissions
Noise emissions
The laptop's noise emissions are fine, without being overly impressive. In idle mode and when completing simple tasks such as office work, playing videos and surfing the web, its noise emissions are fine at about 30 dB(A). However, under load, the 14-inch device is louder than the competition with the Arc 8—and that despite its weaker performance, albeit 40-45 dB(A) is still somewhat okay. If you want something quieter, then you might want to make use of battery-saving mode, although in doing so, the laptop's performance is severely limited.

Temperature
Its case temperatures are similar to those of the competition. While its case remains cool in idle mode (25°C on top and 26 °C on the bottom), under load, we measured peaks of up to 43 °C (top) and 48 °C (bottom), which is still acceptable.
(±) The maximum temperature on the upper side is 43 °C / 109 F, compared to the average of 35.9 °C / 97 F, ranging from 21.4 to 59 °C for the class Subnotebook.
(-) The bottom heats up to a maximum of 48 °C / 118 F, compared to the average of 39.4 °C / 103 F
(+) In idle usage, the average temperature for the upper side is 25.4 °C / 78 F, compared to the device average of 30.7 °C / 87 F.
(±) Playing The Witcher 3, the average temperature for the upper side is 36 °C / 97 F, compared to the device average of 30.7 °C / 87 F.
(+) The palmrests and touchpad are cooler than skin temperature with a maximum of 31 °C / 87.8 F and are therefore cool to the touch.
(-) The average temperature of the palmrest area of similar devices was 28.3 °C / 82.9 F (-2.7 °C / -4.9 F).

Stress test
The stress test using the tools Furmark and Prime95 didn't reveal any nasty surprises. Although the Core Ultra 5 125H hit the 100-°C mark at the beginning, its temperature quickly balanced out at an unalarming 80 °C. Our gaming test with The Witcher 3 resulted in similar values (see screenshots).
Speakers
Compared to the Yoga Pro 7, which has pretty good speakers, the IdeaPad Slim 5's sound quality is significantly worse. According to our audio analysis, its bass is particularly weak, so you should connect a headset or an external sound system to adequately enjoy media.

Power management
Power consumption
Lenovo could also do with improving its power requirement a little. In idle mode, the 14-inch device uses more power than most of the Arc 8 laptops, namely 5-16 watts. Under load, its consumption reached 48-70 watts, which is similar to the Asus ZenBook 14.

Runtimes
While the competition boasts a battery capacity of 68-75 Wh, the IdeaPad Slim 5 only offers 57 Wh, which leaves its runtimes lacking. In view of its mediocre capacity and suboptimal consumption values (when plugged in), just under 9 hours of surfing the web with the brightness reduced to 150 cd/m² is still respectable.

Pros
Cons
Verdict
If you can make peace with a reflective display surface, then the IdeaPad Slim 5 14IMH9 is a successful all-round/multimedia laptop, in almost every way. The Core Ultra 5 125H's debut has—for the most part—been a success. Thanks to its Arc iGPUs, Intel has finally caught up with the Radeon 680M and 780M after many years of trailing behind—although AMD could have already pulled ahead again if it hadn't been resting on its laurels.
Irrespective of this, Lenovo has done lots right with its IdeaPad Slim 5 14.
Its case makes a high-quality impression and it offers a better keyboard compared to what you usually get within this price class. Its weight, battery life and emissions barely give you any reason to complain, either. On the other hand, many potential buyers might be deterred as a result of its RAM being soldered on, preventing it from being expanded. In addition, you'll have to make do with mediocre sound and a slightly outdated selection of ports (no Thunderbolt 4, only HDMI 1.4b).
All-in-all, the 14-inch device has just missed out on getting a "very good" rating, like the HP Spectre x360 14 or the Intel/AMD version of the Yoga Pro 7 14 managed. Its overall rating is more similar to the ZenBook 14 from Asus, which is (also) more expensive.
Price and availability
At the time of writing, the Lenovo IdeaPad Slim 5 14IMH9 with the Core Ultra 5 125H is not yet available to purchase online in the United States. It will likely retail for around US$1,000.
