The screen shows relatively slow response rates in our tests and may be too slow for gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 76 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (21 ms). | ||

The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.165 (minimum) to 636 (maximum) ms. » 40 % of all devices are better. This means that the measured response time is similar to the average of all tested devices (32.9 ms). |
Screen Flickering / PWM (Pulse-Width Modulation)
Screen flickering / PWM detected | 200 Hz | ≤ 20 % brightness setting | |
The display backlight flickers at 200 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 20 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 200 Hz is relatively low, so sensitive users will likely notice flickering and experience eyestrain at the stated brightness setting and below. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8774 (minimum: 5 - maximum: 343500) Hz was measured. |

O LapBook Air se vê e se sente incrível considerando o baixo preço de $400. A tela IPS de 1080p é nítida, a opção de armazenamento interno secundária é rara e inclusive o teclado é iluminado. Infelizmente, o fabricante teve que fazer alguns cortes profundos em quase todos os outros lugares para atingir o preço impossivelmente baixo.
Para começar, a garantia de qualidade não está à altura das alternativas mais conhecidas. Nossa unidade de teste sofre de "bleeding" moderado da iluminação de fundo da tela, iluminação do teclado irregular, uma tecla Ctrl quebrada, uma porta USB defeituosa, falhas múltiplas e uma borda dobrada. Recomendamos que os novos proprietários testem cada porta e tecla para garantir que não haja nada danificado fisicamente. Em segundo lugar, o processador Celeron passivamente resfriado, o SSD primário e o carregador de CA são todos muito lentos. Os usuários que querem algo um pouco mais poderoso estariam melhor com um portátil ULV Haswell mais antigo que provavelmente terá teclas mais firmes e trackpads mais precisos. Se usado principalmente para streaming e reprodução de vídeos em movimento, no entanto, o LapBook Air não é ruim.
O LapBook deve ser útil para aqueles que planejam somente navegar na web, processamento de texto e transmissão de conteúdo de vídeo.
