Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 1000 Hz | ≤ 90 % brightness setting |  |
The display backlight flickers at 1000 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 90 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 1000 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 8747 (minimum: 5 - maximum: 343500) Hz was measured. | |||

Contra
Nenhuma mudança fundamental foi feita no ThinkPad X380 Yoga, quando comparado ao seu antecessor (Thinkpad Yoga 370). Além de um novo nome, a Lenovo também apresenta um novo processador ULV quad-core da Intel.
O processador Core i7-8550U incorporado oferece desempenho mais que suficiente para trabalho de escritório e navegação na Internet. O processador pode utilizar seu Turbo boost apenas de forma limitada e por um curto período de tempo.
Tudo somado, o Lenovo ThinkPad X380 Yoga pode ser descrito como um sucesso. É por isso que as falhas (cintilação PWM, garantia de um ano, sem antenas WWAN) parecem ainda mais irritantes. De fato, nessa faixa de preços, essas falhas não devem surgir em primeiro lugar.
Um SSD NVMe muito veloz, possibilita um sistema muito responsivo. O SSD pode ser substituído. Para isso, você terá que abrir a carcaça, o qual não deve apresentar nenhum problema. Quando a carcaça estiver aberta, você terá acesso ao slot do modem LTE. O slot do cartão SIM também é fornecido. No entanto, a instalação de um modem LTE está fora de questão, porque nosso dispositivo de teste não possui antenas WWAN.
O teclado iluminado deixou uma boa impressão. Não admira: Já conhecemos este teclado do ThinkPad Yoga 370. Além disso, precisamos mencionar a boa duração da bateria. A tela táctil baseada em IPS oferece ótimos ângulos de visão, bom contraste e alto brilho. No entanto, não esperamos ver a cintilação PWM em um dispositivo com esse preço.
A Lenovo deve realmente repensar sua política de garantia de um ano. É óbvio que os compradores atacadistas negociam seus próprios termos de suporte. Mas este fato não serve para os compradores varejistas. Os modelos do ThinkPad X380 Yoga vendidos em lojas de varejo ou online deveriam ter, no mínimo, uma garantia de três anos. O preço do conversível e os propósitos que a Lenovo alega que o dispositivo deve atender demandam tal garantia.
