Lenovo ThinkPad X12 Detachable G2 review: The versatile laptop-tablet hybrid for everyday business use
Never change a running system.
The Lenovo ThinkPad X12 G2 business Windows detachable is designed to be particularly flexible. It allows users to work either in laptop mode or without a keyboard dock in tablet mode and offers long runtimes. A stylus for the touchscreen is also included. We put the flexibility promises to the test.Christian Hintze, 👁 Christian Hintze, ✓ Anton Avdyushkin (translated by DeepL / Ninh Duy) Published 🇩🇪 🇫🇷 ...
Verdict - Good detachable, but hardly anything new apart from Core Ultra
The Lenovo ThinkPad X12 Detachable G2 is a stable and reliable business tablet that can also work well on the go thanks to the comparatively good keyboard dock and the optional 4G connectivity. Even under stress, it never gets really hot and the fans hardly draw attention to themselves in everyday office use.
However, you shouldn't expect any miracles in terms of performance, because despite a small increase in performance compared to the 3-year-old predecessor, the current X12 is also not suitable for demanding (3D) applications. In general, it is a little surprising that hardly anything has changed despite the 3-year break, even the panel is the same as on the predecessor. Of course, a good concept doesn't need any unnecessary improvements, but in three years there have been some technical innovations, for example, the display could have been given a higher refresh rate or more brightness, and the SSD could have been better cooled.
Pros
Cons
Price and availability
The X12 can be extensively configured in the Lenovo store. In the US, users can purchase the detachable laptop via common retailers such as Amazon.

There aren't too many 12-inch business Windows convertibles and detachables; this niche is usually reserved for ARM devices based on Android and the like. As a result, Lenovo has taken its time with the ThinkPad X12 Detachable G2, since the G1 predecessor was released in 2021. In the meantime, the 12-inch market has been ceded to competitors such as the Microsoft Surface Pro or the Dell Latitude 7350 Detachable. In our review, we granted the previous G1 an 88 percent rating.
We are therefore particularly curious to see what changes Lenovo has made to the device during this time, test the performance of the Core Ultra 5 134U in the small case and check whether the X12 can also hold its own against larger competitors.
Specifications - Core Ultra 5 134U in the ThinkPad X12
Case & equipment - Hardly anything new after a 3-year break
Despite the three-year break, hardly anything has changed on the outside. The dark gray to black top of the X12 is made of sturdy, slightly roughened magnesium, while the the display is covered with edge-to-edge glass. Only the detachable keyboard unit is made of plastic, but like the tablet unit, it is very sturdy. Neither part cracks or can be twisted particularly strongly. There is a stand on the back of the tablet, as the lower half can be folded out to form a stand. The tablet alone weighs just under 750 g, together with the keyboard unit it is 1,100 g (with stylus).
There are no noticeable gaps and the overall build quality appears to be of a high standard. The power button is located on the upper edge on the right, the volume rocker is located in the lower area on the right edge and the left side is reserved for the few ports.
Even for a (Windows) tablet, there are very few of them: two USB-C ports and an audio jack output, that's it. Only the upper of the two USB ports supports Thunderbolt 4; the lower port transfers data at a maximum of 10 Gbit/s. As soon as the lower port is connected to the charging cable, we still have exactly one USB-C port available. An external dock is almost mandatory, at least when using it as a laptop. In addition to a Kensington port, there is only the SIM slot, which has space for a nano-SIM.
The infrared selfie webcam has an official resolution of 5 MP, of which 3.7 MP is actually available for video, the rest is used for AI functions. In photo mode, 5 MP can be set in 4:3. The rear main camera has an 8 MP resolution. Despite 5 MP, the selfie pictures appear blurred and lacking in contrast, quite unlike the good webcam in the Acer Swift Go 14 AI. The weak 5 MP camera has been a sad tradition on the X12 since 2021. The main camera, on the other hand, is usable and takes much better photos.
The familiar Intel AX211 module with WiFi 6E is responsible for Wi-Fi. The transfer rates are very high in both 6 GHz and 5 GHz.
As a tablet, maintenance is naturally somewhat difficult, but theoretically possible with the X12. However, the screen has to be removed for this, so maintenance is very inconvenient for normal users.
Sustainability
According to Lenovo, the ThinkPad X12 Gen 2 uses 90 percent recycled magnesium for the top cover, 30 percent recycled plastic for the keyboard cover, and 90 percent recycled plastic for the power supply unit. In addition, the cardboard packaging is FSC-certified and the plastic films are made from 85 percent recycled plastic.
Input devices - X12 with magnetic ThinkPad key dock
Due to the small 12-inch form factor, the keys on the keyboard dock are inevitably somewhat smaller than usual. The arrow keys in particular, but also some others, are quite small, and Lenovo didn't want to do without the Copilot key, so the right Alt and Ctrl keys, in particular, are crowded together. In general, there don't seem to have been any changes here since 2021, but that's not necessarily a bad thing - the ThinkPad X12 model is already pretty good for a docking keyboard.
The touchpad measures approx. 10 x 5.5 cm, with the three dedicated keys above it and the ThinkPad-typical red trackpoint on the keyboard. A small fingerprint sensor for Windows Hello is integrated to the right of the touchpad, which was already the case in 2021.
Display - X12 without experiments
It's interesting to see how little Lenovo has done with the X12 since the G1 from 2021, even the reflective touch display with 1,920 x 1280 pixels seems to be exactly the same model, the Lenovo N123NCA-GS1 with 60 Hz. Its surface is covered with Corning Gorilla Glass 3.
The brightness is around 400 nits, the black level is mediocre, the contrasts are okay, and the response times are slow. There is currently only this one option in the Lenovo configurator, which almost completely covers the sRGB color space, but nothing more.
The values also reflect the subjective impression, the display definitely does not stand out negatively, but does not shine with its color splendor either.

The panel is not optimally adjusted at the factory; we measured quite high DeltaE values in the colors and grayscale, tested against the sRGB color space. Thanks to our own calibration using Calman software and the X-Rite colorimeter, we were able to reduce the deviations in both the greyscale and the colors to below 1.

With a brightness of around 400 nits, the X12 would be quite well equipped for outdoor use, but the reflections from the glossy display are annoying in bright light. The gray November therefore suits the X12, but probably not the soon trembling hands of the user.
Performance - Leap forward thanks to Ultra 5 134U
With an Intel Core Ultra 5 134U and a generous 32 GB of RAM, the X12 tablet is both energy-efficient and well-designed for office work. A 512 GB NVMe SSD completes the equipment. Lenovo offers configuration options. While the display cannot currently be changed, you can choose a slightly more powerful CPU variant, the Intel Core Ultra 7 164U (+220 euros); the version with 16 GB of RAM is also available (-80 euros).
Test conditions
Although the ThinkPad X12 Detachable comes with Lenovo's Commercial Software pre-installed, it does not include any performance modes, which is why we rely on the Windows power modes, where we opt for Best Performance.
Processor
The Intel Core Ultra 5 134U is an energy-saving mid-range CPU, has 2 P and 8 E cores as well as two additional low-power efficiency cores, and therefore has a total of 14 threads.
In the Cinebench R15 loop, we see that the continuous performance is very constant compared to the predecessor, but the short-term performance is not significantly higher. A look at the power consumption shows that the CPU works with up to 30 W for a short time, but then drops back to around 10 W. In Best Performance mode, the laptop can maintain the 30 W slightly longer than in Balanced mode, but interestingly, the continuous performance is slightly higher in the latter (9 vs. 11 W).
Across all CPU tests, however, our X12 G2 can outperform its G1 predecessor by a good 36 percent, quite unlike its bigger brother ThinkPad X13 2-in-1. This puts it pretty much on par with the older Intel Core i5-1235U in the Microsoft Surface Laptop Go 3. The slightly larger 13-inch competitors - Surface Pro with Snapdragon or the Dell Latitude Detachable - are faster, however.
In battery mode, just like in energy-saving mode, 20 W is only reached for a short time, then the TDP drops to 7 W, which reduces the performance by around 23 percent.

DPC latencies
If you start the LatencyMon software, serious latencies only occur when opening several browser tabs. However, the value is rather low in comparison and the playback of our 4K/60 fps YouTube video also runs without dropped frames. The detachables from Dell and Microsoft have significantly higher latency values.

Mass storage
Lenovo uses the well-known SN740 from Western Digital with 512 GB. Models with 256 GB or 1 TB of mass storage are also available from Lenovo. In our SSD best list the not-so-fresh storage is ranked 258th.
Unfortunately, the mediocre SSD in the thin X12 tablet is also throttled very quickly. In our endurance test, the performance drops by around 50 percent from the 3rd DiskSpd pass! To be fair, the storage in the Surface Laptop Go 3 is not faster than the throttled performance of the X12 from the outset. On the other hand, the SSDs in the Dell and Microsoft detachable are significantly more stable and therefore perform better over a longer period.

Graphics card
An Arc-based Intel Graphics with 4 cores is integrated into the SoC. It is significantly less powerful than its Arc relatives, but more efficient and energy-saving.
In the synthetic 3DMark tests, the X12 and the Dell Latitude 7350 Detachable are on par. The Microsoft Surface Pro Copilot+ is 16 percent faster and the iGPU in the X12 calculates about 10 percent slower than the average laptop with the same iGPU from our database, which is not surprising for the small form factor. Compared to the Predecessor the new X12 still has a lead of 28 percent.
The latter looks a little different in gaming, but unfortunately we lack a lot of benchmark data from the predecessor. In Dota 2 Reborn, the lead is similar to the 3DMarks (29 percent), while the predecessor performs even better in X-Plane 11.11. The Dell Latitude has a slight lead of 6 percent, but the MS Surface Pro is over 40 percent ahead. Overall, even with the new X12, you can't play current or demanding titles such as Baldur's Gate 3 or Cyberpunk 2077 smoothly, the 3D performance is only sufficient for older and less demanding games such as DOTA 2 Reborn.
The 3D performance drops by around 17 percent in a new Fire Strike run away from the power grid.

Emissions & energy - X12 is quiet and cool
Noise emissions
In the test, the tablet impressed us with its quiet and calm operation. Even in Best Performance mode, it always remains quiet when idle. And the fans are hardly noticeable in the usual everyday tasks via Office or when surfing. Even in 3DMark06, the Detachable was barely loud at around 28 dB. We measured 38 dB under Cyberpunk 2077, which is also a comparatively low value; the two main competitors also get significantly louder at higher performance.

Temperature
Under maximum continuous load, we measured hot spots of a maximum of 42 °C on the back left and centrally near the display. All other areas rarely exceed 35 °C, so the tablet unit remains relatively cool. Here the Surface Pro is slightly warmer, the Dell Latitude remains slightly cooler.
(±) The maximum temperature on the upper side is 40 °C / 104 F, compared to the average of 35.4 °C / 96 F, ranging from 19.6 to 60 °C for the class Convertible.
(±) The bottom heats up to a maximum of 42 °C / 108 F, compared to the average of 36.8 °C / 98 F
(+) In idle usage, the average temperature for the upper side is 23.7 °C / 75 F, compared to the device average of 30.3 °C / 87 F.
(+) 3: The average temperature for the upper side is 31.7 °C / 89 F, compared to the average of 30.3 °C / 87 F for the class Convertible.
(+) The palmrests and touchpad are cooler than skin temperature with a maximum of 28 °C / 82.4 F and are therefore cool to the touch.
(±) The average temperature of the palmrest area of similar devices was 28 °C / 82.4 F (0 °C / 0 F).

Power consumption
The measurements show that the system can consume up to 50 W, especially in CPU-heavy applications. However, this value is not maintained and soon drops to 20 to 25 W. Incidentally, the latter is also the power consumption of GPU-heavy applications such as gaming.
In comparison, the everyday consumption is lower than that of the Dell Latitude 7350 and in some cases significantly lower than that of the Surface Pro. We measured a temporary maximum consumption of 53 W in the stress test, a value that the small 65 W USB-C power supply can easily deliver.

Battery life
The small case contains a battery with 42 Wh, which is just as much as in the predecessor or the Surface Laptop Go 3. The Surface Pro and the Dell only have slightly larger batteries. Nevertheless, our X12 cannot translate its economical operation into better runtimes than the competition; depending on the test, the Dell and Microsoft even last longer in some cases. It can outlast its direct predecessor with around 11.5 hours in our video test, but the Surface Pro only goes out 50 minutes later.

Notebookcheck overall rating
The Lenovo ThinkPad X12 Detachable G2 is a stable, economical, quiet and reliable business companion with a 4G option. Apart from the new Core Ultra updates, the admittedly good concept of the 3-year-old predecessor has hardly been expanded or improved with new ideas.
