„Lenovo ThinkPad X1 Nano Gen 2“ (2022 m.) apžvalga

There are a number of great laptops that meet PCMag's definition of an ultraportable at under three pounds, but notebooks under two pounds are as scarce as hen's teeth. That's why we were delighted by the February 2021 Lenovo ThinkPad X1 Nano, a 13-inch productivity partner that limbo'd under the line at 1.99 pounds. The new X1 Nano Gen 2 (starts at $1,511; $2,147 as tested) narrowly misses that cut, but is still ultralight at 2.13 pounds (2.19 pounds, if you get it with a touch screen). It's a worthy rival to the Apple MacBook Air M2 and the Dell XPS 13 Plus, but it falls a bit short of our favorite, slightly pricier ultraportables, the 13.5-inch HP Elite Dragonfly G3 and Lenovo's own 14-inch ThinkPad X1 Carbon Gen 10.

The Design: The Score Is 16:10 

Like a growing number of laptops, the ThinkPad X1 Nano trades the familiar 16:9 widescreen aspect ratio for a slightly taller 16:10—in this case, a 2,160-by-1,350-pixel IPS panel rated at 450 nits of brightness. The $1,511 base model sports a 12th Generation Intel Core i5-1240P processor, 16GB of RAM, and a 512GB NVMe solid-state drive. Our $2,147 test unit steps up to a Core i7-1280P (six Performance cores, eight Efficient cores, 20 threads), 32GB of memory, and a 1TB drive.

Clad in the familiar matte black magnesium and aluminum of other ThinkPads with a carbon fiber hybrid lid, the Nano Gen 2 is a trim 0.57 by 11.5 by 8.2 inches, even more compact than the 2.7-pound MacBook Air (0.44 by 12 by 8.5 inches). The system has passed MIL-STD 810H torture tests for road hazards like vibration, shock, and temperature extremes; there's almost no flex if you grasp the screen corners or press the keyboard deck. 

The screen bezels aren't ultra-thin, but the top bezel makes room for a face recognition webcam with sliding privacy shutter. A fingerprint reader next to the touchpad gives you a second way to skip typing passwords with Windows Hello. As with larger ThinkPads, the touchpad is joined by Lenovo's TrackPoint mini joystick embedded in the keyboard, with three buttons below the space bar. Wi-Fi 6E and Bluetooth are standard, with 4G or 5G mobile broadband optional.

Like the Dell and Apple ultraportables, the Lenovo is short on ports, with only two USB-C/Thunderbolt 4 ports joined by an audio jack on its left edge. There's nothing on the right side except cooling vents and the power button. We're all for skinny laptops, but we hate having to carry adapters to plug in an external monitor or USB Type-A storage device, so we prefer lightweights like the Carbon and Dragonfly that provide HDMI and USB-A as well as Thunderbolt connectors.

Lenovo Knows Keyboards 

ThinkPads are famous for having first-class keyboards, and the Nano is no exception—the backlit keyboard offers a wonderfully snappy typing feel and a fine layout including real Home, End, Page Up, and Page Down keys instead of double-duty cursor arrows. (The Fn and Control keys are in each other's place at bottom left, but you can swap their functions with the provided Lenovo Vantage utility.) 

Top-row shortcuts include keys to place and end video calls, as well as the usual brightness and volume controls. The touchpad is smallish due to the system's size, but it glides and taps smoothly and clicks quietly.

The face recognition webcam offers 1080p instead of the lowest-common-denominator 720p resolution. It captures well-lit and colorful images with good detail and no static. A User Presence Sensing feature uses face recognition to offer Zero Touch Login and Lock as you approach or walk away, and it can save battery power by dimming the display when you look away. Weirdly, the feature kept working even when I turned it off in Lenovo Vantage; I thought I wouldn't be able to run our battery-life test until I discovered it can be disabled in BIOS setup. (Our battery test relies on the screen brightness being at a constant level throughout.)

Besides the above-mentioned features, Lenovo Vantage offers AI-based Wi-Fi security, audio optimization for VoIP calls, and dynamic, music, movie, game, and voice presets for Dolby Audio. Two upward- and two downward-firing speakers pump out reasonably loud, somewhat hollow sound. Bass is absent, but there's no distortion at high volume, and you can make out overlapping tracks.

The Nano's unusual 2,160-by-1,350-pixel resolution is a good fit for its 13-inch screen, providing sharp detail without making things squinty-small. The IPS panel offers wide viewing angles and high contrast. Brightness is ample, and colors are rich and well saturated, though they don't pop like poster paints. White backgrounds look clean instead of dingy, helped by a screen hinge that goes all the way back.

Testing the ThinkPad X1 Nano Gen 2: Five Under Three Pounds 

For our benchmark charts, we compared the ThinkPad X1 Nano Gen 2 to its above-mentioned rivals: the Dell XPS 13 Plus, the M2 version of the Apple MacBook Air, and the HP Elite Dragonfly G3. That left one spot which we filled with a budget-priced ultraportable, the 2.48-pound Microsoft Surface Laptop Go 2. You can see their basic specs in the table below.

Produktyvumo testai 

Pagrindinis UL PCMark 10 etalonas imituoja įvairias realaus pasaulio produktyvumo ir turinio kūrimo darbo eigas, kad būtų galima įvertinti bendrą našumą atliekant į biurą orientuotas užduotis, tokias kaip tekstų apdorojimas, skaičiuoklės, interneto naršymas ir vaizdo konferencijos. Taip pat atliekame „PCMark 10“ viso sistemos disko testą, kad įvertintume nešiojamojo kompiuterio įkėlimo laiką ir pralaidumą. 

Following those, three further benchmarks focus on the CPU, using all available cores and threads, to rate a PC's suitability for processor-intensive workloads. Maxon's Cinebench R23 uses that company's Cinema 4D engine to render a complex scene, while Primate Labs' Geekbench 5.4 Pro simulates popular apps pradedant PDF atvaizdavimu ir kalbos atpažinimu iki mašininio mokymosi. Galiausiai naudojame atvirojo kodo vaizdo įrašų perkodavimo įrenginį HandBrake 1.4, kad konvertuotume 12 minučių trukmės vaizdo įrašą iš 4K į 1080p raišką (geresnis laikas mažesnis). 

Mūsų galutinis produktyvumo testas yra Puget Systems PugetBench for Photoshop, kuris naudoja garsiosios Adobe vaizdų rengyklės Creative Cloud 22 versiją, kad įvertintų kompiuterio našumą kuriant turinį ir daugialypės terpės programas. Tai automatizuotas plėtinys, atliekantis įvairias bendras ir GPU pagreitintas „Photoshop“ užduotis, pradedant nuo vaizdo atidarymo, pasukimo, dydžio keitimo ir išsaugojimo iki kaukių, gradiento užpildų ir filtrų taikymo.

The X1 Nano Gen 2 easily cleared the 4,000 points in PCMark 10 that show excellent productivity for Microsoft Office or Google Workspace, and it performed well in Photoshop. But its CPU scores were lower than we expected considering its 28-watt Intel P-series rather than 15-watt U-series processor. The cheaper, Core i5-based Surface Laptop predictably brought up the rear. 

Grafikos testai 

Testuojame „Windows“ kompiuterių grafiką su dviem „DirectX 12“ žaidimų modeliavimais iš UL 3DMark, „Night Raid“ (kuklesnis, tinka nešiojamiesiems kompiuteriams su integruota grafika) ir „Time Spy“ (reiklesnis, tinka žaidimų įrenginiams su atskirais GPU). 

Taip pat atliekame du bandymus iš kelių platformų GPU etalono GFXBench 5, kuris pabrėžia tiek žemo lygio rutiną, kaip tekstūravimas, ir aukšto lygio, žaidimo tipo vaizdo atvaizdavimas. 1440p Aztec Ruins ir 1080p Car Chase testai, pateikti ne ekrane, kad būtų galima pritaikyti skirtingas ekrano skiriamąsias gebas, pratimų grafika ir skaičiavimo šešėliai naudojant OpenGL programavimo sąsają ir aparatinės įrangos teseliaciją. Kuo daugiau kadrų per sekundę (fps), tuo geriau.

We've tested scores of laptops with Intel's Iris Xe integrated graphics and never found one suitable for gaming or graphically demanding apps. This group continues the streak—they're fine for casual gaming or streaming video, but not intended for first-person shooters or workstation-class CGI. 

Baterijos ir ekrano testai 

Tikriname nešiojamųjų kompiuterių baterijos veikimo laiką leisdami vietoje saugomą 720p vaizdo failą (atvirojo kodo Blender filmą Plieno ašaros(Atidaroma naujame lange)) kai ekrano šviesumas yra 50%, o garso garsumas - 100%. Prieš bandymą įsitikiname, kad baterija yra visiškai įkrauta, o Wi-Fi ir klaviatūros apšvietimas išjungtas. 

Taip pat naudojame Datacolor SpyderX Elite monitoriaus kalibravimo jutiklį ir jo „Windows“ programinę įrangą, kad išmatuotų nešiojamojo kompiuterio ekrano spalvų sodrumą – kiek procentų sRGB, „Adobe RGB“ ir DCI-P3 spalvų gamų ar palečių ekranas gali rodyti, ir jo 50 proc. ryškumas nitais (kandelos kvadratiniam metrui).

The MacBook Air and the OLED-screened XPS 13 Plus have the most dazzling, colorful displays here, though the Lenovo's is nice and bright. The Nano managed to outlast the Dell in our battery rundown, but its stamina is far short of the Apple and HP ultraportables'.

Verdict: One of the Lightest and Nicest 

If you can live without luxuries like an OLED screen, the Lenovo ThinkPad X1 Nano Gen 2 is a fairly priced, highly capable ultraportable. It misses Editors' Choice honors because of its scanty array of ports and decent but not notable battery life, but wins points for its high-quality keyboard and screen, and available LTE. As for weighing 2.13 instead of last year's 1.99 pounds, well, we're a bit over our target weight ourselves.
