220-1101 Question 177
Single answerTypesA user brings in a laptop and says the built-in display is cracked after being dropped. The laptop powers on and works normally when connected to an external monitor. You need to order the correct replacement part before disassembling the system. Which laptop display type should you verify first to make sure the replacement panel is compatible?
- A
The connector type and pin count used by the LCD panel
- B
The version of Windows installed on the laptop
- C
The amount of system RAM installed
- D
The type of SSD interface in the laptop
Show answer and explanation
Correct answer: A
Explanation
This question tests practical knowledge of laptop display types and replacement considerations in an A+ Core 1 hardware scenario. In real-world laptop repairs, technicians must confirm more than just screen size. They typically verify the exact display panel type, including connector type, pin count, supported resolution, backlight/interface standard, and sometimes touch vs. non-touch capability. Manufacturer service manuals and parts lists are best-practice sources for confirming compatibility. CompTIA A+ Core 1 expects candidates to recognize hardware component types and apply that knowledge to repair scenarios, especially with laptop-specific parts where seemingly similar components may not be interchangeable.
- A. Correct.
Correct. When replacing a laptop screen, one of the most important compatibility checks is the panel connector type and pin count, such as whether the display uses a particular eDP connector layout. Even if the screen is the same size, resolution, and mounting style, an incompatible connector can prevent installation or proper operation. In real repair work, technicians commonly verify the exact panel model or hardware maintenance documentation before ordering.
- B. Incorrect.
Incorrect. The Windows version does not determine physical LCD panel compatibility. A cracked laptop display is a hardware issue, and the replacement must match the laptop's supported display specifications rather than the operating system installed.
- C. Incorrect.
Incorrect. System memory capacity has no direct relationship to which replacement laptop display panel is required. Someone might choose this if they are thinking broadly about hardware specifications, but RAM does not affect LCD fitment or connector compatibility.
- D. Incorrect.
Incorrect. The SSD interface, such as SATA or NVMe, is unrelated to the type of replacement display panel needed. This distractor reflects a common mistake of focusing on unrelated internal components instead of the specific hardware subsystem being repaired.
