Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 24880 Hz | ≤ 40 % brightness setting |  |
The display backlight flickers at 24880 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 40 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 24880 Hz is quite high, so most users sensitive to PWM should not notice any flickering. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8705 (minimum: 5 - maximum: 343500) Hz was measured. | |||

ThinkPad E480 är en lockande laptop med kraftfulla komponenter för ett överkomligt pris. Men man ska inte förblindas av ett papper med statistik eller en teori: I slutändan så är prestanda i praktiken det som räknas.
E480 har verkligen mycket som talar för denna billiga ThinkPad. Detta inkluderar det uppfräschade höljet, som övertygar oss med sin kvalitet. Även på den positiva sidan finns inmatningsenheterna. I denna kategori där ThinkPad-modeller vanligtvis är starka så begår E480 knappt några misstag. Särskilt tangentbordets bakgrundsbelysning är riktig bra. Precis som dess TrackPoint. Dess styrplatta, däremot, är inte riktigt perfekt, men tack vare Windows precisionsdrivrutiner så är den ändå väldigt exakt. Vad det gäller anslutningar så uppskattade vi verkligen det faktum att Lenovo tillslut har valt att inkludera en USB Typ-C i E-serien, särskilt då anslutningarna på E480 erbjuder alla möjliga funktioner - förutom Thunderbolt. Expansionsmöjligheterna är exemplariska, för utöver två RAM-platser så levererar E480 också en tom plats för en 2.5-tums hårddisk eller SSD. En annan positiv aspekt är skärmen: den är inte brilliant, men det är en matt IPS-skärm med bra kontrastvärden och inga riktiga svagheter - utöver färgrymdstäckning, vilket är normalt i den här prisklassen.
Nackdelarna är i huvudsak relaterade till dom inre egenskaperna hos E480, dock inte uteslutande så. Det är förkastligt, till exempel, att Lenovo använder en MicroSD-kortplats trots att det finns mer än tillräckligt med plats för en SD-kortplats. Värre är den inbyggda SSD-enheten, som är alldeles för långsam för en PCIe-NVMe-SSD och nästan är ett bedrägeri då den besegras av SATA-III SSD-enheter. Men det största problemet med E480 är kylsystemet, som är fullständigt överväldigat av komponenterna. Detta är inte direkt uppenbart från prestandatapp i det vardagliga livet, utan märks snarare av en irriterande fläkt och alldeles för höga temperaturer på utsidan: 71.6 °C är ett toppvärde vi inte vill mäta av på någon laptop. Jämfört med denna negativa bottennivå, som kan orsaka brännskador hos användaren, så är våra andra nackdelar: medioker batteritid, reducerad GPU-prestanda vid batteridrift och den korta garantitiden nästan obetydliga.
Bort med händerna: Om du inte vill bränna dig i knät, undvik ThinkPad E480 konfigurerad med denna AMD-GPU.
Trots dess utmärkta förhållande mellan pris och prestanda kan E480 inte rekommenderas i den här konfigurationen. Förvisso: Temperaturerna uppmättes i ett stress-test. Men höljet borde också bli varmt på liknande vis i spel. Vi avråder från att använda E480 utrustad med AMD-grafik på grund av den potentiella hälsorisken.
Detta är ett väldigt beklagligt omdöme, för E480 har definitivt potential. Det hade varit särskilt intressant att se hur versionen utan AMD-GPU presterar - vi antar att höljet hade hållt sig mycket svalare. Därför kan E480 konfigurerad med Intel UHD 620 kanske vara värd en rekommendation. En motsvarande testenhet är redan på väg till oss. Annars finns det alternativ från andra tillverkare såsom HP ProBook 440 G5 och Dell Latitude 3490.
