Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 25510 Hz | ≤ 50 % brightness setting |  |
The display backlight flickers at 25510 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 50 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 25510 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 8743 (minimum: 5 - maximum: 343500) Hz was measured. | |||

O Lenovo ThinkPad A285 finalmente oferece aos usuários a chance de adquirir um portátil ThinkPad compacto baseado em um processador AMD. Além de três modelos básicos, o dispositivo compacto de 12,5 polegadas pode ser ainda mais configurado e está disponível com recursos úteis, como um leitor de cartão inteligente ou scanner de digitais. O fabricante também oferece um módulo WWAN opcional, para que você possa usar Internet na estrada.
O Ryzen 5 Pro 2500U da AMD é um bom processador para o A285 e oferece bastante desempenho para tarefas comuns. O processador é comparável a um Intel Core i5-8250U, mas não para cargas de trabalho contínuas. O X280 com a CPU Intel é mais rápido, mas isso também é resultado de diferentes configurações do TDP, que foram definidas pela Lenovo.
A maior diferença entre os dois chips é o adaptador gráfico integrado. A Radeon Vega 8 da AMD é uma unidade muito mais rápida e pode facilmente superar o Intel UHD Graphics 620 nos benchmarks.
Nosso modelo de teste do Lenovo ThinkPad A285 é vendido por 1439 Euros (~$1640). Gostamos particularmente dos excelentes dispositivos de entrada, e o SSD PCIe de 256 GB garante altas taxas de transferência para um bom desempenho do sistema. O chassi robusto e de alta qualidade completa o pacote. Ele inclina a balança em apenas 1,1 kg (~2,4 lb), para que você possa carregá-lo facilmente ou colocá-lo em sua bolsa.
O Lenovo ThinkPad A285 é um bom dispositivo de escritório baseado em um processador AMD e se beneficia do preço mais baixo comparado ao X280. O A285 é uma boa opção se você não precisar do desempenho adicional da CPU do X280 ou dos tempos de duração mais longos da bateria.
Ainda existem algumas desvantagens, como o aumento do consumo no modo inativo, que afeta o tempo de duração da bateria em comparação com o X280. A tela em nosso modelo de teste também é um pouco pior, mas isso é resultado da loteria de paineis da Lenovo. O fabricante conta com diferentes fornecedores e você nunca sabe qual painel você obterá antes da compra.
A memória soldada é definitivamente um mau desenvolvimento para dispositivos comerciais e você não pode atualizá-la mais tarde. O A285 também não possui suporte para Thunderbolt 3 do X280. Ainda assim, a impressão geral do dispositivo é boa e podemos recomendá-lo. Ainda vamos ver se os usuários estão dispostos a mudar para um sistema AMD para seu dispositivo de negócios, mas o preço mais baixo é
