Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 544 Hz |  | |
The display backlight flickers at 544 Hz (worst case, e.g., utilizing PWM) . The frequency of 544 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 8715 (minimum: 5 - maximum: 343500) Hz was measured. | |||

Contra
Fino e leve é o nome do jogo com o IdeaPad 730S, e a Lenovo certamente tem a vantagem competitiva nesse quesito. Seu formato minúsculo e sua construção peso pena (apenas 1,094 kg) são acompanhadas por uma espessura de apenas 11,9 mm, que está entre os ultraportáteis mais finos atualmente disponíveis. A estabilidade é preservada, tanto quanto possível, graças a uma carcaça de alumínio e uma tela coberta de vidro - embora esta última seja um pouco mais suscetível a torções do que nos sentimos confortáveis.
Embora decepcione principalmente em termos de desempenho e conectividade da CPU, o IdeaPad 730S de 870 dólares é uma alternativa razoável e acessível aos líderes de categoria ultraportáteis bem estabelecidos.
O 730S também possui uma tela FHD atraente, com bom brilho e contraste, e renderização de cor surpreendentemente precisa (embora a gama ainda seja apenas 61% do AdobeRGB). Os dispositivos de entrada são de alta qualidade, considerando o tamanho e o preço da máquina. O desempenho geral do sistema é potente graças ao muito rápido SSD NVMe e à falta geral de gargalos significativos em outros lugares. A máquina é muito silenciosa e esquenta desconfortavelmente. Finalmente, ficamos agradavelmente surpresos com os alto-falantes, que são bastante fortes e funcionam bem na maior parte do espectro.
As maiores decepções com a unidade de teste de hoje começam com o desempenho sustentado da CPU, que está bem abaixo do de seus pares e limitado fortemente por restrições térmicas. A nova abordagem de resfriamento incorporada pela Lenovo (que engloba tanto a cavidade do teclado quanto a grade inferior) em conjunto com a única ventoinha pequena não parece acompanhar as demandas do Core i5 na unidade de teste de hoje - então temos sérias reservas sobre considerar uma atualização para o Core i7, que custa um pouco mais, mas que provavelmente ainda funcionaria abaixo da maioria das máquinas concorrentes equipadas com Core i5. Mesmo desde o início, o desempenho da CPU é menor do que o de concorrentes equipados de forma semelhante, mas continua a cair ainda mais sob estresse de longo prazo até chegar a 20 a 30% abaixo de alguns concorrentes (veja: Microsoft Surface Laptop 2, Dell XPS 13 9380).
A seleção de portas também é um pouco chata, sem espaço para nada além de algumas portas Thunderbolt 3 reconhecidamente versáteis, uma porta USB tipo C Gen 1 e uma porta de áudio combinada. Além disso, gostaríamos de ver uma opção de tela anti refletiva, embora a estabilidade da tampa da tela possa estar na raiz dessa escolha de design (graças ao aumento da rigidez do vidro, que está ausente nos modelos anti-reflexo).
Ainda assim, se a portabilidade estiver no topo da lista de prioridades, o desempenho da CPU não é uma grande preocupação, e as restrições de refletividade da tela/conectividade não são um fator decisivo, o IdeaPad 730S é uma ótima alternativa acessível aos líderes de categoria dos ultraportáteis bem estabelecidos.
