Kort testrapport Lenovo IdeaPad S540-15IML laptop: Uitstekende batterijduur

Spiegeltje, spiegeltje aan de wand. De 15-inch IdeaPad S540-15IML maakte tijdens onze tests niet alleen indruk met een hoogwaardige metalen behuizing, maar ook met een uitstekende batterijduur. We kunnen echter niet begrijpen waarom Lenovo voor een glanzend beeldscherm heeft gekozen.

Responstijd Scherm

De responstijden van het scherm tonen hoe snel het scherm in staat is om van één kleur naar de andere te veranderen. Trage responstijden kunnen aanleiding geven tot 'nabeelden' rond bewegende objecten of het scherm wazig maken (blur). Vooral spelers van snelle 3D-games hebben baat bij een scherm met snelle responstijden.
       Responstijd Zwart naar Wit
34.8 ms ... stijging ↗ en daling ↘ gecombineerd↗ 18.8 ms stijging
↘ 16 ms daling
Het scherm vertoonde trage responstijden in onze tests en is misschien te traag voor games.
Ter vergelijking: alle testtoestellen variëren van 0.8 (minimum) tot 240 (maximum) ms. » 90 % van alle toestellen zijn beter.
Dit betekent dat de gemeten responstijd slechter is dan het gemiddelde (24.4 ms) van alle geteste toestellen.
       Responstijd 50% Grijs naar 80% Grijs

Het scherm vertoonde trage responstijden in onze tests en is misschien te traag voor games.
Ter vergelijking: alle testtoestellen variëren van 0.8 (minimum) tot 636 (maximum) ms. » 81 % van alle toestellen zijn beter.
Dit betekent dat de gemeten responstijd slechter is dan het gemiddelde (38.8 ms) van alle geteste toestellen.

Screen Flickering / PWM (Pulse-Width Modulation)

Om de schermhelderheid te verlagen schakelen sommige laptops het backlight erg snel aan en uit. Dit gebeurt aan een dergelijk hoge frequentie dat het niet zichtbaar is voor het menselijk oog. Als de frequentie te laag is kunnen personen met gevoelige ogen geïrriteerd geraken, hoofdpijn krijgen en zelfs flickering waarnemen.
Screen flickering / PWM waargenomen 202 Hz ≤ 99 % helderheid instelling

Het backlight van het scherm flikkert aan 202 Hz (hoogstwaarschijnlijk met PWM - Pulse-Width Modulation) aan een helderheid van 99 % en lager. Boven deze helderheid zou er geen flickering / PWM mogen optreden.

De frequentie van 202 Hz is redelijk laag en de meeste mensen die gevoelig zijn aan flickering kunnen dit dus waarnemen of geïrriteerde ogen krijgen (gebruikmakend van de vermelde helderheid en lager).

Ter vergelijking: 51 % van alle geteste toestellen maakten geen gebruik van PWM om de schermhelderheid te verlagen. Als het wel werd gebruikt, werd een gemiddelde van 17612 (minimum: 5 - maximum: 2500000) Hz waargenomen.

Lenovo IdeaPad S540-15IML, testmodel geleverd door:

Een uithoudingskampioen met een stijlvolle metalen behuizing voor €800? Wat in eerste instantie onwaarschijnlijk klinkt, wordt een realiteit met de Lenovo IdeaPad S540-15IML.

Voor het volledige, Engelse testrapport, klik hier.

Bijna geen enkele andere allround laptop kan zichzelf zo goed redden zonder stroomvoorziening. Samen met het lage gewicht (1,9 kg) en de platte behuizing (1,7 cm) is deze 15-inch laptop voorbestemd voor mobiel gebruik.

Als alleen het glanzende beeldscherm dat buitenactiviteiten lastiger maakt en zelfs veel binnenactiviteiten bemoeilijkt niet aanwezig was. Een mat paneel zou veel beter geschikt zijn geweest voor het apparaat en vooral beter geschikt voor het totale concept.

Als je deze tekortkoming echter accepteert, krijg je een aan te bevelen en grotendeels zeer succesvolle multimedia-laptop.
