LG Gram 15Z980 är den obesegrade mästaren bland tunna och lätta laptops på 15 tum. Det finns dock kompromisser som kommer med denna enhet på 1.1 kg. Totalt sett gillar vi LG:s försök att göra enheten lättare utan att göra den tunnare bara för sakens skull.
Magnesiumlegeringen känns lyxig men är mottaglig för tryck och vridning. Kombinationen av materialval och låg vikt gör att enheten känns ömtålig. Men en MIL-STD-810G certifiering och hållbarhetstester från populära YouTube-kanaler motverkar till viss del den känslan.
Totalt sett är LG Gram 15Z980 en imponerande ultramobil arbetshäst som är extremt lätt och har utmärkt batteritid. Det är bara synd att LG inte säljer den på fler ställen.
Vidare kan 15Z980 inte använda sin Core i7-8550U CPU fullt ut. Vår testenhet kunde bara matcha enheter med Core i5-8250U i prestandatesterna. Dessutom har LG utrustat vår testenhet med en långsam SATA III SSD som inte kan tävla med mycket snabbare NVMe-enheter. Tyvärr klarar enheten bara av den långsammare SATA III-standarden. Ett trevligt drag är en extra M.2-2280 plats om du behöver en.
Det finns också många andra positiva aspekter. 16 GB RAM som körs i dualkanalsläge hjälper till med att få ut mesta möjliga ur den integrerade GPU:n. 15Z980 har dessutom ett gediget utbud av portar inklusive tre USB 3.0 Typ A-portar och en Thunderbolt 3-port.
På det hela taget känns tangentbordet bra att skriva på, men det tar lite tid att vänja sig vid. Det finns några knappar i storlekar som inte är standard som till en början känns lite besvärliga. Dessutom kunde vi bara välja ett Spanskt QWERTY-tangentbord. Men det är trevligt att ett numeriskt tangentbord ingår, då inte alla enheter på 15 tum har ett sådant.
FullHD-skärmen är ljusstark nog och har ett bra kontrastförhållande och skaplig färgprecision. Frustrerande nog minskar den maximala ljusstyrkan betydligt vid batteridrift. Det finns eventuellt en inställning någonstans som åtgärdar detta, men vi kunde inte hitta en under våra tester. Detta kombinerat med en kraftigt reflekterande skärm gör det till en svår uppgift att använda 15Z980 utomhus.
Vår testenhet höll sig relativt sval och tyst även vid extrem belastning. Dessutom har 15Z980 exceptionellt lång batteritid som utklassar våra jämförelseenheter.
Intressant nog hade 15Z980 fått ett omdöme på 84% som en kontorslaptop men 86% som en subnotebook. Vi har valt att kategorisera enheten i den sistnämnda kategorin på grund av sin mobilitet jämfört med andra enheter på 15 tum.
