A user has been having issues charging a laptop after turning it on and has noticed the laptop screen is dim. Which of the following components most likely needs to be replaced?
Given the symptoms described (dim laptop screen and charging issues after turning it on), the most likely component that needs to be replaced is:
D. Inverter
Explanation:
The inverter is a component in a laptop that is responsible for providing power to the backlight of the LCD screen. If the inverter is malfunctioning, it can result in a dim or completely dark screen.
Issues with the inverter can also impact the laptop's ability to charge, as power-related problems may affect various components.
While it's possible to find older laptops or specific models that still use inverters, it's not common in today's market. (So another outdated question that is not applicable going into 2025)
D
An inverter is a component that converts DC power to AC power for the backlight of an LCD (liquid crystal display) screen. If the inverter is faulty, the screen may appear dim or dark, even if the brightness settings are adjusted. Replacing the inverter may fix the issue. The LCD itself, the video card, and the digitizer are not related to the screen brightness problem.
