CompTIA A+ Core 1 (220-1101) — Question 313

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?

Answer options

• A. LCD
• B. Video card
• C. Digitizer
• D. Inverter

Correct answer: D

Explanation

The inverter is responsible for powering the backlight of the LCD screen; if the screen is dim, it likely indicates that the inverter is malfunctioning. The LCD itself may be functional, and the video card and digitizer are not directly related to screen brightness issues. Therefore, replacing the inverter is the most appropriate solution.
