Courte critique de l'ultraportable Fujitsu Lifebook U938 (i5-8250U, LTE, SSD, FHD)

Sven Kloevekorn / Sascha Mölck (traduit par JBP), 07/11/2018

Luxe léger. Par rapport à son prédécesseur, le LifeBook U938 est légèrement plus léger. Le plus gros changement reste l’intégration d’un processeur quadricœur, mais pas grand-chose d’autre n’a changé. L’autonomie est toujours honnête, mais reste en retrait par rapport aux rivaux.

Scintillement / MLI (Modulation de largeur d'impulsion)

Afin d'abaisser la luminosité de l'écran, certains ordinateurs portables font varier très rapidement le rétroéclairage entre éteint et allumé. La fréquence à laquelle le rétroéclairage s'éteint et se rallume est normalement fixée à une valeur qui permet de rendre la variation indétectable à l'œil nu? Si la fréquence est trop basse, certaines personnes peuvent être sujettes à une fatigue oculaire, des maux de tête ou même percevoir les variations.
Scintillement / MLI (Modulation de largeur d'impulsion) décelé 217 Hz ≤ 20 Niveau de luminosité

Le rétroéclairage de l'écran scintille à la fréquence de 217 Hz (certainement du fait de l'utilisation d'une MDI - Modulation de largeur d'impulsion) à un niveau de luminosité inférieur ou égal à 20 % . Aucun scintillement ne devrait être perceptible au-dessus de cette valeur.

La fréquence de rafraîchissement de 217 Hz est relativement faible, les personnes les plus sensibles devraient percevoir un scintillement et être sujettes à une fatigue oculaire accrue (avec le niveau de luminosité indiqué)

En comparaison, 54 % des appareils testés n'emploient pas MDI pour assombrir leur écran. Nous avons relevé une moyenne à 10647 (minimum : 43 - maximum : 588200) Hz dans le cas où une MDI était active.

Temps de réponse de l'écran

Le temps de réponse d'un écran mesure la rapidité à laquelle l'écran est capable de changer une couleur pour une autre. Un temps de réponse élevé se traduit par une image floutée pour les objets en mouvement. Les joueurs bénéficieront de faibles latences d'affichage en jeu.
       Temps de réponse noir à blanc
29 ms ... hausse ↗ et chute ↘ combinées↗ 16 ms hausse
↘ 13 ms chute
L'écran souffre de latences relativement élevées, insuffisant pour le jeu.
En comparaison, tous les appareils testés affichent entre 0.8 (minimum) et 240 (maximum) ms. » 67 % des appareils testés affichent de meilleures performances.
Cela signifie que les latences relevées sont moins bonnes que la moyenne (25.9 ms) de tous les appareils testés.
       Temps de réponse gris 50% à gris 80%
43 ms ... hausse ↗ et chute ↘ combinées↗ 21 ms hausse

L'écran souffre de latences très élevées, à éviter pour le jeu.
En comparaison, tous les appareils testés affichent entre 0.9 (minimum) et 636 (maximum) ms. » 59 % des appareils testés affichent de meilleures performances.
Cela signifie que les latences relevées sont similaires à la moyenne (41.5 ms) de tous les appareils testés.

Le principal argument du LifeBook U938 est très certainement son châssis fin et léger. A un peu moins de 1 kg, il surclasse ses concurrents Dell et Lenovo. Le Core i5-8250U possède assez de puissance pour n’importe quelle tâche classique. Mais, tout comme chez les concurrents du même segment, il ne peut utiliser tout son potentiel. Au moins ceux-ci offrent-ils des fréquences légèrement plus élevées, et donc un niveau général de performances légèrement supérieur.

Le système est rapide et fluide grâce à son SSD, qui peut être échangé contre un modèle plus gros ou plus rapide, en retirant la coque inférieure. Vu le prix de l’appareil, nous aurions souhaité y voir un SSD NVMe au lieu du SSD SATA III que Fujitsu a intégré.

Le LifeBook U938 est un ultraportable très léger et compact. Mais nous sommes très déçus que Fujitsu ait choisi d’ignorer les critiques faites au prédécesseur, et ait gardé les faiblesses de l’appareil au lieu de les corriger une fois pour toutes.

Le clavier est plutôt solide et large, mais il n’est pas rétroéclairé. L’autonomie est honnête, mais inférieure à celle de la plupart des concurrents. Au moins le modem 4G / LTE permet une connectivité en déplacements.

L’écran mat IPS est très lumineux, possède un bon contraste, des angles de vision élevés, et une couverture de l’espace colorimétrique tout à fait correcte en sortie d’usine. Néanmoins, l’écran est l’un des plus gros point faible de l’appareil : il se tord très facilement, et peut être de ce fait facilement abimé. Nous n’avons pas apprécié non plus que le ventilateur du U938 émette des couinements dès qu’il fonctionnait. Cela ne devrait pas arriver dans un appareil à ce prix.
