Question
For several years, your laptop's monitor has worked perfectly. However, shortly after turning on your laptop today, you notice that the dimness has increased on the screen.
Which of the following is the MOST likely cause? (Select two.)
answer
The power adapter was accidently unplugged.
The brightness level was automatically reset to the default settings.
The monitor's inverter has gone bad.
The monitor's hertz rate is set too high.
The monitor's resolution was automatically reset to the default settings.
Solution
Para resolver esta pregunta, vamos a analizar cada una de las opciones proporcionadas:
-
The power adapter was accidently unplugged.
- Si el adaptador de corriente se desconecta, el laptop podría cambiar automáticamente a un modo de ahorro de energía, lo que puede reducir el brillo de la pantalla para conservar la batería. Esta es una causa probable.
-
The brightness level was automatically reset to the default settings.
- Es posible que la configuración de brillo se haya restablecido a los valores predeterminados, lo que podría resultar en una pantalla más tenue. Esta también es una causa probable.
-
The monitor's inverter has gone bad.
- El inversor del monitor es responsable de proporcionar la energía necesaria para iluminar la pantalla. Si el inversor falla, la pantalla puede volverse muy tenue o incluso completamente oscura. Esta es una causa probable.
-
The monitor's hertz rate is set too high.
- La tasa de hertz (frecuencia de actualización) no afecta directamente el brillo de la pantalla. Por lo tanto, esta opción es menos probable.
-
The monitor's resolution was automatically reset to the default settings.
- La resolución de la pantalla afecta la claridad y la cantidad de información que se puede mostrar, pero no afecta directamente el brillo. Por lo tanto, esta opción es menos probable.
Las dos causas más probables son:
- The power adapter was accidently unplugged.
- The monitor's inverter has gone bad.
