Lenovo ThinkPad T490 (i7, MX250, Low Power FHD) Laptop rövid értékelés

Benjamin Herzig, 👁 Andreas Osthoff (fordította Zoltán Kiss), 06/30/2019
Whiskey Lake ThinkPad Ultrabook Laptop / Notebook Business

Ha karcsúbb, akkor jobb - vagy mégsem? A ThinkPad T490 a központban levő ThinkPad sorozat, a T sorozat radikális újratervezése. A Lenovo sokkal jobb mobilitást hangsúlyoz egy kompaktabb, vékonyabb és könnyebb vázzal. Ez felveti a kérdést, hogy a Lenovo-nak kompromisszumokat kellett-e tennie a javítások érdekében. Ezúttal legalább a Lenovo nem spórol a képernyőn.

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 2451 Hz ≤ 50 % brightness setting

The display backlight flickers at 2451 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 50 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 2451 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9384 (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
45.6 ms ... rise ↗ and fall ↘ combined↗ 22.8 ms rise
↘ 22.8 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 98 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (25 ms).
       Response Time 50% Grey to 80% Grey
74 ms ... rise ↗ and fall ↘ combined↗ 33.6 ms rise
↘ 40.4 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. » 98 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (39.8 ms).

Papíron egyértelmű, hogy a Lenovo ThinkPad T490 a ThinkPad T480 utódja. A valóságban azonban a ThinkPad T490 dizájnja radikálisan más, ezért helyénvaló, hogy a T480 és T480s keverékének nevezzük, nem pedig a T480 egyenes utódjának. Ez a keverék többnyire jól sikerült, de vannak gyengeségek is.

A ThinkPad T490 egy erős, magnéziummal megerősített műanyagból készült vázzal rendelkezik, amely jóval könnyebb és kompaktabb, mint a T480 váza. Csatlakozási opciók bőven vannak, ahogy a rendelkezésre álló biztonsági funkciók is, valamint LTE (opcionális) és teljes méretű RJ45 kommunikációs opciók is a Wi-Fi mellett. Ahogy a ThinkPad-től megszokott, a bemeneti eszközök nagyon jók. A legnagyobb újítás a régebbi ThinkPad generációkhoz viszonyítva a képernyővel kapcsolatos. A Lenovo végre egy kiváló minőségű FHD képernyőt alkotott, jó fényerővel és színskálával. A ThinkPad T490 CPU teljesítménye átlagon felüli, a magasabb TDP-nek köszönhetően, és az opcionális Nvidia GeForce MX250 még a könnyedebb játszást is lehetővé teszi, a T490 még sokoldalúbbá téve. A jó teljesítmény ellenére a ThinkPad T490 ventilátorai csendesek, és jó az üzemidő. Végül, de nem utolsósorban pedig, az általunk tesztelt T490 garanciacsomagja nagyvonalú.

Bár a képernyő amúgy az egyik legjobb érv a ThinkPad T490 mellett, a válaszideje rendkívül rossz, és a gyors kurzormozgások ghosting-ot eredményeznek. A T490-nek rengeteg portja van, de sajnos a Lenovo az SD kártyanyílást microSD-kártyanyílásra cserélte - véleményünk szerint szükségtelen változtatás. Szintén sajnálatos, hogy a Thunderbolt 3 port csak két PCIe sávon keresztül csatlakozik. A 14 hüvelykes képernyővel rendelkező összes újabb T/X ThinkPad-ek közül a T490 a legbővíthetőbb modell, de a váz nehezen nyitható és zárható. A terhelés alatti magas hőmérséklet szintén problémás, mivel túllépi a fontos 50 °C-os küszöböt. A jó teljesítmény és a csendes ventilátor végül mégsem válik be teljesen, mivel fellépett a fojtás a stressz tesztünkben is. A T490 másik problémája a zaj, amit kiad: "coil whine"-tól és hangszóró zúgástól szenved. Végül, gyászoljuk a PowerBridge funkció elvesztését - az USB C akkumulátorok ugyanazt a funkciót szolgálhatják, de a PowerBridge egy érdekes és kényelmes funkció volt.

A Lenovo ThinkPad T490 a hagyományos T-sorozat legújabb modellje - a Lenovo sok változtatást hajtott végre az előző modellhez képest. Bár nem minden változás volt pozitív, mindent figyelembe véve, a ThinkPad T490 jobb laptop, mint a T480.

Összességében a Lenovo ThinkPad T490 egy nagyon jó üzleti laptop, de a Lenovo szoftverfrissítéssel kijavíthatná a hangszóró zúgását. Továbbra is kérdés, hogy a gyengébb iGPU hűtőrendszer képes-e lehűteni a processzort. Alapvetően ajánljuk a ThinkPad T490-t, de a felhasználók jobb, ha egy kis teljesítményű FHD képernyős vagy QHD LCD-s modellt választanak.
