Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 990 Hz |  | |
The display backlight flickers at 990 Hz (worst case, e.g., utilizing PWM) . The frequency of 990 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 8746 (minimum: 5 - maximum: 343500) Hz was measured. | |||

Como qualquer bom ThinkPad (ou, mais amplamente, qualquer máquina de empresarial de sucesso), são as coisas fundamentais que são o alicerce do sucesso do T480. Ainda presentes na configuração atual, é claro, todos os elementos básicos que aplaudimos durante nossas duas últimas avaliações: sólida construção CFRP de magnésio/híbrido, dispositivos de entrada de alta qualidade, muitas portas e opções de segurança robustas. O T480s é de fato um dos principais portáteis de escritório atualmente disponíveis, rivalizado por poucos em sua classe.
No entanto, para aqueles que podem ter encontrado anteriormente um preço de quase $2.000, difícil de engolir, a configuração de hoje de (aproximadamente) $1.600 somente apresenta sacrifícios menores em termos de desempenho geral. A CPU Core i5-8250U se posiciona acima da maioria dos concorrentes equipados da mesma forma, e o ainda SSD NVMe—embora abaixo do nível do ultra veloz PM981—permanece muito rápido, apesar de tudo. A opção de GPU MX150 faz sentido para aqueles interessados em um desempenho gráfico mais rápido, o Core i7 fornece um desempenho marginalmente melhor (tanto single- e multi-core), e, talvez mais significantemente—a tela WQHD está muitas ligas acima do painel FHD de hoje, que apresenta uma severa falta de saturação de cor e oferece um brilho apenas médio. Mas para um portátil de escritório básico, muito rápido e confiável, a configuração atual do T480s encaixa no perfil perfeitamente.

Concorrentes como a venerável série Latitude 7000 da Dell (especificamente neste caso, o 7490 e 7390), o HP EliteBook 840 G5, e o excelente X1 Carbon da própria Lenovo, todos oferecem seu singular conjunto de benefícios, sem mencionar as garantias de 3 anos no local, contra a garantia de 1 ano do T480s, mas poucos conseguem alcançar o desempenho do T480s. Pelos nossos testes, um T480s equipado com um Core i5 pode ser tão capaz (ou mais) quanto um Dell Latitude 7000 ou HP EliteBook 840 equipado com um i7. É difícil errar com qualquer um destes dispositivos, mas com o T480s, a Lenovo claramente tem um vencedor em suas mãos.
