Kort testrapport Dell Latitude 5280 (7200U, HD) Laptop
Klein en sterk. Dell is erin geslaagd een aanzienlijk lichtere behuizing te creëren nu de verouderde E-Port stilaan tot het verleden behoort. Het ontbreken van Thunderbolt 3 is echter een ernstige beperking voor de docking-capaciteiten van dit nieuwste Latitude-ontwerp.

Een belangrijk verkoopargument van de meeste zakelijke notebooks is de mogelijkheid om eenvoudig docking-stations of secundaire batterijen aan te sluiten. Nu de Latitude 5280/5480/5580 de E-Port heeft laten vallen, is Thunderbolt 3 nog crucialer geworden om extra features te ondersteunen. De Latitude 5280 mist helaas beide poorten en is bijgevolg minder veelzijdig dan de 5480 en 5580, ook al is hij kleiner en mobieler. Daarnaast is de systeemventilator steeds actief, wat we onnodig vinden voor een notebook die slechts met een U-processor is uitgerust.
Als de hierboven genoemde nadelen geen afknappers zijn, is de 5280 een echte uitblinker in de meeste andere categorieën. Zijn USB Type-C-poort laat nog altijd toe om via DisplayPort externe monitors te verbinden en de nieuwe behuizing is veel lichter dan de E5270 zonder dat dit merkbaar ten koste gaat van stabiliteit. De batterijduur is uitstekend voor de middelste batterij-optie en het behoud van zowel VGA- en HDMI-output zal zonder twijfel van pas komen in de context van een universiteitslokaal of conferentieruimte. CPU-prestaties zijn erg indrukwekkend aangezien de processor in staat is om de maximale Turbo Boost-snelheid zelfs onder erg hoge belasting aan te houden.
We raden aan om het ondermaatse 768p-scherm links te laten liggen en te opteren voor de helderdere 1080p-variant en een snellere primaire SSD. De verhoging in resolutie en helderheid zal het gebruikscomfort ten goede komen en is absoluut de investering waard als je het systeem vaak zonder externe monitors zal gebruiken.
Het ietwat sponsachtige toetsenbord vergt wat tijd om gewoon te worden en gebruikers met grotere handen kunnen toestellen van dit formaat beter vermijden voor langere periodes van typen. De 5280 is meer geschikt voor gebruikers die voortdurend onderweg zijn dan voor wie zijn toestel vooral stationair gebruikt thuis of op kantoor.
