Test: Lenovo ThinkPad X380 Yoga (i7-8550U, FHD) Omvandlingsbar (Recension)

Sascha Mölck, Stefanie Voigt (översatt av Daniel Eriksson), 03/20/2018

Samma hölje men med ett annat namn. ThinkPad X380 briljerar med en snabb NVMe SSD, ett tunt hölje och utmärkt batteritid. Den inbyggda fyrkärniga Core i7 CPU:n kan inte upprätthålla sin fulla prestanda. Operativsystemet Windows ingår inte. Men Linux-användare kommer vara mycket glada över Linux-kompatibiliteten hos denna omvandlingsbara dator.

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM detected 1000 Hz ≤ 90 % brightness setting

The display backlight flickers at 1000 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 90 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 1000 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 52 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8773 (minimum: 43 - maximum: 142900) Hz was measured.

Display Response Times

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.
       Response Time Black to White
29 ms ... rise ↗ and fall ↘ combined↗ 15 ms rise
↘ 14 ms fall
The screen shows relatively slow response rates in our tests and may be too slow for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 68 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (25.6 ms).
       Response Time 50% Grey to 80% Grey
50 ms ... rise ↗ and fall ↘ combined↗ 24 ms rise
↘ 26 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 84 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (41 ms).

Läs den fullständiga versionen av den här recensionen på engelska här.

Inga fundamentala ändringar har gjorts med ThinkPad X380 Yoga jämfört med dess föregångare (ThinkPad Yoga 370). Utöver ett nytt namn så har Lenovo också lagt till en ny fyrkärnig ULV-processor från Intel.

Den inbyggda Core i7-8550U processorn erbjuder mer än tillräckligt med prestanda för kontorsarbete och internet-surfande. Processorn kan använda sin Turbo Boost till en viss grad och för en kort stund.

Totalt sett kan Lenovo ThinkPad X380 Yoga beskrivas som lyckad. Därför framstår bristerna (PWM-flimmer, ett års garanti, inga WWAN-antenner) ännu mer irriterande. Faktum är att i detta prisskiktet så borde sådana nackdelar inte ens dyka upp överhuvudtaget.

En väldigt snabb NVMe SSD resulterar i ett väldigt responsivt system. SSD-enheten kan bytas ut. För att göra det behöver du öppna upp höljet, men detta borde inte vara ett problem. När höljet väl är öppet har du tillgång till platsen för ett LTE-modem. En SIM-kortsplats finns också. Men att faktiskt installera ett LTE-modem är uteslutet då vår recensionsenhet saknar WWAN-antenner.

Det bakgrundsbelysta tangentbordet lämnade ett gott intryck. Vi är inte förvånade: vi känner redan till det här tangentbordet från ThinkPad Yoga 370. Vidare så måste vi nämna den bra batteritiden. Vi förväntar oss dock inte att se PWM-flimmer på en enhet med en sån här prislapp.        

Lenovo borde verkligen tänka om kring sin ettåriga garantipolicy. Det är uppenbart att grosshandlare förhandlar om sina egna villkor för support. Men detta hjälper inte slutkonsumenten alls. ThinkPad X380 Yoga-modellerna som säljs i butik eller online borde, åtminstone, komma med tre års garanti. Prislappen på denna omvandlingsbara och dom syften som Lenovo påstår att enheten är till för kräver en sådan garanti.
