  • Lenovo ThinkPad X12 Detachable Gen 1

The ThinkPad X12 Detachable Gen 1 is is Lenovo’s acknowledge to the very staunch Microsoft Ground Pro 7+. Each are tablets with detachable keyboards and a commercial zigzag. Whereas the Ground Pro 7+ has high-end cachet, on the choice hand, the ThinkPad X12 is more about worth.

This overview is an part of our ongoing roundup of the ideal laptops. Mosey there for recordsdata on competing merchandise and the very best seemingly device we examined them.

Lenovo ThinkPad X12 Detachable Gen 1 (20UW0012US) fundamental formulation

Of the seven diverse configuration alternate choices of the ThinkPad X12 Detachable Gen 1 on Lenovo’s web establish of residing, our overview unit (the 20UW0012US, $2,229 on appears to be like to be popular, going inner and out of stock as we wrote this overview. The tablet sold out on Amazon, as successfully. Lenovo gives diverse fundamental configurations of the X12 Detachable that initiating with 8GB of RAM, which we’d save in mind somewhat skimpy if diverse alternate choices come in.

It’s very grand worth noting that unlike the rival Microsoft Ground Pro 7+, Lenovo bundles a keyboard somewhat than making you pay extra for it. A pen is extra-fee (the keyboard comes with a pen loop). A Lenovo pen with 2,048 ranges of ink sensitivity is the more inexpensive option; a separate Lenovo pen with 4,096 ranges of ink sensitivity is concerning the double the worth. 

Right here are the remainder of the principle specs. The establish there are many alternate choices (a lot like with CPU, RAM, etc.), the formulation on our particular mannequin are indicated by the words “as examined” in parentheses after the merchandise.

Whereas Microsoft’s Ground tablets dangle constantly been aimed at a huge market of creators, patrons, and specialists, Lenovo has aimed its ThinkPad purely at specialists—and it reveals in the build.

Lenovo ThinkPad X12 Detachable Gen 1 kickstand lip Impress Hachman / IDG

Your fingers will prefer to obtain the small lip to drag out the kickstand, a solution which I found seriously tense. No longer just like the competing Microsoft Ground Pro tablets, there’s no microSD card slot hiding below.

The ThinkPad X12 Detachable Gen 1 maintains the boxy, dark ThinkPad comely, the use of a magnesium alloy for the chassis discipline cloth. Although proper a smidgen thicker than the Ground Pro 7+, the squared traces undoubtedly make contributions to the premise that here’s indeed a “detachable,” which favors keyboard use, somewhat than a frail tablet that would clutch it or leave it. 

A wedge kickstand reclines nearly flat, to about 10 levels off the horizontal. You’ll prefer to develop some fumbling about to obtain the small tab that folds it out, though. The kickstand supports the ThinkPad X12 Detachable firmly till its point of ideal recline, where it becomes seriously springy.

The factual side of the Lenovo ThinkPad X12 Detachable Gen 1 hides a volume rocker and a Kensington lock slot.

If there’s the leisure I undoubtedly hate concerning the ThinkPad X12 Detachable, though, it’s the anemic grip that the keyboard has on the tablet itself. With the keyboard unfolded, shifting the Detachable at some stage in the house in general methodology grabbing the tablet itself…and off pops the keyboard, time and yet once more. Even worse, the tablet doesn’t constantly electrically reconnect to the keyboard when reattached, meaning that I needed to fiddle with it—disconnect, reconnect—till it at last labored. It’s no longer a big watch when it be necessary to pop the keyboard on and off to enable a product love the ThinkPad X12 Detachable Gen 1 to determine of the box. 

That’s earlier than the ThinkPad X12 Detachable went overboard. As I modified into once finishing the overview, I establish the related tablet and keyboard on my lap. The keyboard released its grip, and the tablet tumbled backward, landing on my toe. The divulge bowed out from the body. I modified into once ready to snap it support in and not using a obvious lack of performance, but peaceable—Lenovo wants to repair this. The mixture of the dilapidated magnetic grip and the skinny, slim fringe of the kickstand methodology that the ThinkPad X12 Detachable ought to peaceable be left on a desk, no longer your lap. We told Lenovo of our experiences, and the company didn’t comment. 

Lenovo ThinkPad X12 Detachable Gen 1 left side reclined Impress Hachman / IDG

On the left, the Lenovo ThinkPad X12 Detachable Gen 1 entails a 3.5mm jack, a Thunderbolt port, the no longer mandatory SIM slot and a 2nd USB-C port for charging. The charging port lacks Thunderbolt capabilities.

The ThinkPad X12 Detachable entails venting in the side and high of the tablet, and it emits an occasional faint divulge while below same outdated use. It’s on the full nearly serene at some point soon of same outdated use. However, the tablet gave the affect in particular relaxed to the ambient temperature of the room. We’ll explore this extra later on in the overview.

For connectivity Lenovo has long past wholly USB-C, with a pair of ports on the left-hand side. Glance closely: A faint glyph next to the higher port indicates the presence of Thunderbolt 4/USB 4. You may most definitely perhaps most definitely also use a USB-C dock with the decrease port. Although the tiny 65W USB-C vitality brick will seemingly be dilapidated in both port, the small poke image tells you it may well most definitely perhaps peaceable be dilapidated on the undeniable USB-C one. I modified into once nervous that the Thunderbolt cables that arrive with some transportable Thunderbolt docks love our Editor’s Different-a hit eradicate, the IOgear Thunderbolt 3 Shuttle Dock, may most definitely moreover very successfully be too brief to hook up with the tablet without dangling the dock in the air. After making an are trying a pair of, though, that doesn’t seem just like the case.

The no longer mandatory SIM slot on the side of the tablet pops out with a same outdated SIM software program. Lenovo also splurged for a backplate for the SIM caddy, lessening the likelihood that your SIM card will drag thru and onto the ground.

Lenovo’s divulge isn’t the leisure to jot down dwelling about, however the matte conceal conceal locations out a pleased 398 nits max, ample for a successfully-lit room. In step with our colorimeter exams, the divulge covers 98 percent of the sRGB coloration gamut, but proper 73 percent of AdobeRGB and 74 percent of the P3 gamut. Which could most definitely perhaps no longer be coloration-right ample for bellow advent, but vivid for all the pieces else.

Keyboard, audio and webcam

Lenovo has constantly had an elite recognition for its keyboards, and the ThinkPad X12 Detachable’s is comparatively staunch. Naturally, the necessary roam (1.3mm, basically based completely on a Lenovo representative) isn’t reasonably as deep as a frail notebook would enable, but there’s refined, constantly firm resistance, and the keys are sizable ample (about 1.5mm square) to be pleased. My fingers initially felt diminutive, but my typing improved over time. The 2 ranges of keyboard backlighting may most definitely moreover be managed by the keyboard itself (Fn + Rental), and likewise by an glorious commercial model of the Vantage machine utility. 

The enduring crimson TrackPoint remains in the center, with a touchpad below. The ThinkPad X12 Detachable’s touchpad is small, and constrained seriously by the discrete buttons at the head—a legacy feature from earlier ThinkPads. They’re genuine, though. Lenovo’s touchpad is in every other case refined and clickable many of the system up and down its size. Gestures labored as expected.

The Lenovo ThinkPad X12 Detachable Gen 1’s audio is subpar. Lenovo entails Dolby Audio Top price enhancement. When the Dolby feature is disabled, song sounded vaguely underwater, jumbled together unpleasantly. Enabling Dolby’s technology couldn’t completely attach it. Whereas the volume is ample, make certain that to pack headphones or earbuds for a staunch aural skills.

The tablet’s consumer-going thru webcam gives 1080p resolution, somewhat than the more conventional 720p cameras that accompany most laptops and tablets. This makes for a sharper image. On the diverse hand, I modified into once dissatisfied by the washed-out coloration and lights, which feels find it irresistible falls in need of what we ought to peaceable request in 2021, put up-pandemic. A 2nd, front-going thru 8MP digicam may most definitely moreover be dilapidated to grab shots or movies of things taking establish in front of you. 

Lenovo ThinkPad X12 Detachable Gen 1 webcam Impress Hachman / IDG

Although the image is comparatively spirited, my navy sweatshirt and kelly green T-shirt fade into a uniform blah. Expectantly here’s a final hurrah for pandemic hair, though.

Lenovo also entails a tiny, handbook lens shutter for the webcam. Once closed, a small crimson dot covers the digicam lens, and a white LED lights up next to the lens to ascertain.  The digicam lens is entirely blocked, and apps that use it (such because the Home windows Camera app) will simply chronicle that no digicam is demonstrate. My handiest criticism is that you just would possibly want to most definitely desire a spare fingernail, nail file, automotive key or something to opt the tiny wander and wander it over; a fingertip doesn’t constantly work.

The webcam works along with the in-keyboard fingerprint reader to provide one amongst basically the most convenient biometric experiences in computing recently. (Each are Home windows Hiya-licensed, and both ship same outdated with the tablet.) In truth, I needed to develop a quantity of ducking proper to enable my finger time to be read earlier than the massive-angle depth digicam picked up my face. 

Apps: Glance is a groovy privateness utility

Lenovo saved the ThinkPad X12 Detachable Gen 1 somewhat bloatware-free, but there are two apps that stand out. First, there is a commercial model of the Lenovo Vantage app, Lenovo’s superior machine utility which may most definitely moreover be dilapidated to govern a quantity of aspects of your PC. It’s clear and strong.

Glance by Mirametrix will seemingly be interesting. It’s somewhat love the Tobii admire-monitoring technology that we first wrote about several years in the past, but with a privateness zigzag. The app gives several formulation, many predicated upon what the depth digicam can watch of your face. If enabled, presence detection appears to be like to be like to watch whilst you occur to’re at the helm. Glance away for too prolonged, and the app blurs your divulge for privateness’s sake. If it could probably “watch” yet any other person in the support of you, this would most definitely develop the same. Leaning too end? A warning will pop up for you to adjust your posture. The app will even smartly remind you to watch far from the conceal conceal each and each twenty minutes or so that you just can abet your eyesight.

This can watch love a blurry describe, but it unquestionably’s undoubtedly the Mirametrix Glance technology blurring and obfuscating the divulge when it thinks you’re no longer paying attention.

Glance struggles with external displays, though. The “clear pointer” component also supposedly teleports your mouse cursor to an external divulge, but it unquestionably never labored. The app required somewhat of fiddling to blur my external video show, too.


Lenovo’s ThinkPad X12 Detachable Gen 1’s sober dark build communicates that it’s designed for productiveness first and main. Our accurate-world exams confirmed that it handles the calls for of the work-from-dwelling establish of job comparatively successfully, though I needed to divulge myself to lag the X12 Detachable with one hand on the keyboard and the diverse on the tablet…or fair fold it up.

Precise-world performance exams had been ample. The tablet’s 16GB of memory is higher than ample for web browsing and Microsoft 365 establish of job apps, and the tablet dropped handiest 8 frames out of 10,000 when examined in opposition to a 4K/60Hz YouTube video. I undoubtedly noticed the YouTube skip a time or two, but it unquestionably took place so usually that it never turned nerve-racking in the slightest.

Whereas we at last request a competing tablet from Dell’s Latitude line, it be at the moment a two-horse poke between it and the Microsoft Ground Pro 7+. (In the graphs following, the Ground Pro 7+ is highlighted in yellow.) The poke is end, though the diversities aren’t profound. We’ve also included the older Ground Pro 7

Acquire in mind that Microsoft dials down the Home windows vitality/performance slider to minimal ranges, while Lenovo maxes it out. We conceal the Ground Pro 7+ outcomes at both that default, and dialed as a lot as prioritize performance, to study with the Lenovo. The yellow bar surrounded by dark is what we recorded with the vitality/performance slider dialed as a lot as “Simplest performance.”

Our performance stories initiating up with UL’s PCMark 10 suite, which has modified the older PCMark 8 suite in our making an are trying out. PCMark 10 measures all the pieces from videoconferencing apps to web browsing to establish of job apps to CAD renders, the use of accurate-world apps when it could probably. Right here, the ThinkPad X12 does better than the Ground Pro 7+ in both performance mode.

What this test reveals is that Lenovo’s ThinkPad X12 Detachable Gen 1 will develop proper vivid in day to day establish of job duties.

We’ve also in contrast the tablet the use of the older PCMark 8 suite for backward compatibility. Each are peaceable relevant, though PCMark 10’s exams are more taxing. The Lenovo ThinkPad X12 Detachable yet once more comes out somewhat sooner than the Ground Pro 7+.

Our Cinebench CPU test makes use of Maxon’s rendering software program to stress-test the CPU in transient bursts, as most duties develop. We use the older R15 test for compatibility’s sake. Cinebench measures how powerfully the ThinkPad X12 will urge below most hundreds, no longer undoubtedly factoring cooling into the equation. Right here, the Ground Pro 7+ in performance mode takes the lead.

  • Lenovo ThinkPad X12 Detachable Gen 1

    Lenovo’s ThinkPad X12 Detachable Gen 1 competes successfully in opposition to Microsoft’s Ground Pro 7+ in the Home windows tablet market, though its strength lies in worth higher than build or performance.
