Test: Lenovo Yoga Book C930 (i5-7Y54, LTE, E-Ink) Omvandlingsbar (Sammanfattning)

Christian Hintze, 👁 Sebastian Jentsch (översatt av Daniel Eriksson), 01/01/2019

3-i-1 Omvandlingsbar. Nya Yoga Book har en E-Ink skärm istället för ett tangentbord och kan ses som en kombination av laptop, surfplatta och e-läsare. Dessutom kan du digitalisera text och bilder med denna allt-i-allo. Enheten är baserad på sin föregångare från 2016 men kommer med många förändringar och förbättringar. Som exempel har den bättra prestanda. Å andra sidan har den tappat minst en funktion. Är 2018 års modell av Yoga Book värd dubbelt så mycket som den gamla versionen kostade? Få reda på det i vår detaljerade recension.

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
27 ms ... rise ↗ and fall ↘ combined↗ 13 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. » 53 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (25.4 ms).
       Response Time 50% Grey to 80% Grey
43 ms ... rise ↗ and fall ↘ combined↗ 23 ms rise
↘ 20 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. » 59 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (40.6 ms).

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 not detected

In comparison: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9603 (minimum: 43 - maximum: 142900) Hz was measured.

Lenovo Yoga Book C930, recensionsex från Notebooksbilliger.de

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

Nya Yoga Book har en E-Ink skärm som gör den väldigt unik. Den största fördelen är dess mångsidighet. Den är extremt liten och lätt och kan användas för att rita på, som en laptop, en surfplatta eller en e-läsare. Men flexibilititen resulterar också i en del kompromisser.

Som exempel är tangentbordet inte lämpat för den som skriver mycket och det är heller inte bakgrundsbelyst. Det magra portutbudet kan vara problematiskt för traditionella laptop-användare. Om det bara är en e-läsare du behöver kan du troligen hitta ännu lättare enheter.

Lenovo Book riktar sig åt personer som vill kombinera alla dess funktioner (tryckkänslighet, penna, e-läsare, osv) i en och samma enhet. Den som letar efter en normal laptop blir nog mer nöjd med en annan enhet.

Oavsett är det förvånande att se hur bra Lenovo har lyckats med att kombinera alla dessa funktioner i en såpass lätt enhet. Designen och de häftiga funktionerna (knackning) gör Book C930 riktigt iögonfallande. Eftersom vi inte har en separat kategori för E-Ink skärmar i vårt utvärderingssystem har vi lagt till två poäng till resultatet manuellt.

En del kan tänkas tycka att priset är en ytterligare nackdel. Med ett utgångspris på 10.500 kronor kostar enheten ungefär dubbelt så mycket som föregångaren gjorde. Utöver de många förbättringarna har en del funktioner också försvunnit. Möjligheten att digitalisera bilder från papper finns inte längre. Den bättre huvudkameran som fanns på den tidigare modellen saknas också och tyvärr är batteritiden betydligt kortare jämfört med föregångaren. Istället har prestandan ökat dramatiskt och dessutom är skärmen bättre. Sist men inte minst: enheten har för tillfället inga riktiga konkurrenter.
