Courte critique de l'Ultraportable HP EliteBook 820 G2

Mise à niveau vers Broadwell. L'EliteBook 820 G2 est un ultraportable de 12,5 pouces dédié aux professionnels. L'impression générale est bonne, mais avec un prix fixé à un peu moins de 2000 euros, l'appareil n'est pas à la portée de toutes les bourses.

Le HP EliteBook 820 G2. Nos remerciements à HP Allemagne.
Le HP EliteBook 820 G2. Nos remerciements à HP Allemagne.

Le HP EliteBook 820 G2 est plus ou moins un 820 G1 sous Broadwell. Si la robe est restée la même, la nouvelle combinaison processeur/carte graphique permet un gain en performances. Le châssis est toujours aussi bon, la maintenance est bien pensée tout comme les périphériques d'entrée. Rien à signaler du côté de la chauffe et de la nuisance sonore. Le ventilateur a néanmoins la fâcheuse tendance de devenir gênant dès qu'il se met en activité. Le modem LTE permet une connectivité un peu partout tant qu'il existe une couverture réseau. La dalle IPS est plaisante à regarder grâce à une grande luminosité et de bons contrastes. Au final, le verdict du test de son prédécesseur s'applique aussi ici :

Le 820 G2 répond pleinement aux exigences des professionnels à la recherche d'un ordinateur portable.
