Test: Lenovo Flex 5 15 (i7-8550U, GeForce MX130) Omvandlingsbar (Sammanfattning)

Allen Ngo (översatt av Daniel Eriksson), 09/05/2018

Inte särskilt flexibel. Lenovos Flex 5 är en billig 2-i-1 som både känns bra och ser bra ut för sitt pris med massor av inbyggda portar. Tyvärr lämnar den mörka skärmen och den dåliga Turbo Boost-prestandan en hel del att önska.

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
29.2 ms ... rise ↗ and fall ↘ combined↗ 17.6 ms rise
↘ 11.6 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. » 70 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (25.8 ms).
       Response Time 50% Grey to 80% Grey
37.6 ms ... rise ↗ and fall ↘ combined↗ 19.2 ms rise
↘ 18.4 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. » 34 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (41.3 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 detected 21190 Hz ≤ 99 % brightness setting

The display backlight flickers at 21190 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 99 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 21190 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8838 (minimum: 43 - maximum: 142900) Hz was measured.

För

+ diskret GeForce MX130-grafik
+ bra konstruktionskvalitet; stabila gångjärn
+ Lenovo Active Pen ingår
+ dubbla interna lagringsplatser
+ respektabel batteritid
+ innanmätet går att komma åt

Emot

- massor av tom outnyttjad plats runt moderkortet
- laddning via propretiär AC-adapter istället för USB Typ C
- konstant fläktljud; väldigt liten kyllösning
- PWM på alla ljusstyrkenivåer förutom maximum
- väldigt dålig Turbo Boost-prestanda
- endast enkelkanals-RAM
- högfrekvent fläktljud
- väldigt mörk skärm

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

Flex 5 är inte för entusiaster eller användare som behöver mycket prestanda, och det vet Lenovo. Detta är istället ett budgetsystem för hemma-användare som vill använda den till multimedia eller studenter som helt enkelt vill ha en billig Windows-laptop med surfplattefunktioner för filmvisning, ordbehandling och något enklare spel då och då. Den har inga särskilda fördelar framför Pavilion 2-in-1Vivobook 2-in-1Envy 2-in-1, eller den tyngre Inspiron 15 2-in-1 utöver att ett långsamt GeForce MX130 GPU finns som tillval. Som en omvandlingsbar för hemmabruk klarar den sig precis.

Listan över oturliga prestandanedskärningar är lång. Den riktigt mörka skärmen innebär att detta i huvudsak är en omvandlingsbar för inomhusbruk och den extremt begränsade Turbo Boost-förmågan innebär att det egentligen inte finns någon anledning att köpa den dyrare Core i7 8550U-varianten när den billigare i5 8250U-modellen presterar i princip likadant. Dess enkelkanals-RAM hämmar prestandan ytterligare och kyllösningen är pinsamt liten med tanke på hur mycket rum det finns i en formfaktor på 15 tum. Det finns gott om plats runt fläkten som kunde ha använts till en större kyllösning för att reducera ljudet från fläkten.

Ett utgångspris på 7.000 kronor är rimligt för ett likgiltigt system som man i ärlighetens namn lätt glömmer medans dyrare varianter kan kostar upp emot 10.000 kronor. Vi rekommenderar att undvika de dyrare alternativen då det i så fall vore bättre att skaffa en mer välgjord traditionell laptop såsom XPS 15 eller lägga på lite pengar för att skaffa en Spectre x360 15. Extremt dålig Turbo Boost och en mörk skärm gör den svårsåld.
