Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 1000 Hz | ≤ 99 % brightness setting |  |
The display backlight flickers at 1000 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 99 % 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 8705 (minimum: 5 - maximum: 343500) Hz was measured. | |||

Contra
O Lenovo ThinkPad A485 realmente tinha um alto potencial: A série ThinkPad T, na qual o ThinkPad A se baseia, é extremamente popular, e há uma grande demanda por bons portáteis Ryzen. No entanto, este ThinkPad Ryzen nos decepciona no teste.
Por um lado, isso é porque a Lenovo desnecessariamente omite a tela QHD do ThinkPad A485, e o A485 também não tem Thunderbolt 3. Além disso, o desempenho da CPU permanece muito atrás do modelo irmão ThinkPad T480 da Intel. Pior ainda é o fato de que o consumo é muito alto, resultando em uma bateria extremamente ruim em comparação. Isso é apenas parcialmente culpa da Lenovo, já que os portáteis com a Ryzen geralmente enfrentam um consumo maior em comparação com os modelos baseados na Intel.
Claro que o Lenovo ThinkPad A485 também tem muitos lados positivos, levando à boa pontuação de avaliação. Estes incluem, por exemplo, a carcaça robusta, os excelentes dispositivos de entrada e o extenso equipamento de conexão. Mas você também pode conseguir tudo isso no ThinkPad T480. Apenas no desempenho gráfico o A485 está na frente, mas só comparado com o T480 com a iGPU. O modelo com a GeForce MX150 também é melhor neste aspecto.
Não recomendado: Tudo o que torna o ThinkPad A485 um bom portátil, o ThinkPad T480 também pode fazer, enquanto também proporciona um melhor desempenho da CPU e melhor duração da bateria do que o A485.
Então, finalmente, não podemos realmente dar uma recomendação para o ThinkPad A485. Na prática, o Lenovo ThinkPad T480 é realmente a melhor opção em todos os aspectos. Por outro lado, se você quiser evitar os processadores da Intel em geral, você deveria escolher o HP EliteBook 745 G5, que tem uma duração de bateria que não é tão ruim e o painel LCD também é melhor até certo ponto neste modelo.
Atualização UEFI versão 1.02: Conseguimos testar novamente o ThinkPad A485 com uma versão mais recente do BIOS UEFI. A duração da bateria agora melhorou um pouco, e o desempenho da CPU sob uso intenso também é maior com o firmware mais novo. Portanto, ajustamos a pontuação da avaliação e também queremos modificar um pouco nosso veredicto: Embora o ThinkPad T480 continue a superar o A485, o ThinkPad A485 pode ser uma opção interessante devido ao seu preço relativamente acessível, especialmente se você precisar de um pouco mais de desempenho da GPU.
