Items

An older laptop with a cold cathode fluorescent lamp (CCFL) backlight displays a extremely faint image that is only visible under direct external light.
A technician needs to select the correct modular memory form factor to upgrade system memory inside a standard compact laptop chassis.
A field technician installs a high-speed internal solid-state drive directly into a small keyed slot on the laptop motherboard using NVMe protocols.
A high-end laptop display panel provides deep contrast and individual pixel illumination without utilizing an inverter or separate backlighting unit.

Matches

Show answer & explanation

Answer

Matching pairs: Faint image on CCFL display matches High-voltage display inverter; Compact laptop RAM upgrade matches SODIMM module; Direct slot NVMe drive matches M.2 PCIe SSD; Self-illuminated panel without backlight matches OLED display panel.
Each laptop hardware diagnostic description directly corresponds to its underlying technology: CCFL displays rely on high-voltage inverters, laptop memory uses the SODIMM form factor, NVMe storage utilizes M.2 slots, and OLED panels eliminate external backlighting components completely.

Step-by-Step Solution

1
Analyze the CCFL backlight power issue
Identify that CCFL tubes rely on a high-voltage display inverter board to convert DC battery power into high-voltage AC power.
A dim screen where an image is visible under light typically points to an inverter or backlight bulb failure.
2
Identify the standard laptop RAM form factor
Select SODIMM as the appropriate physical form factor.
Full-size desktop DIMM modules cannot physically fit into laptop memory slots.
3
Identify compact high-speed storage interfaces
Match direct motherboard slot NVMe installation to M.2 PCIe SSD.
M.2 form factor drives plug into dedicated M.2 slots for high-speed PCIe NVMe connectivity.
4
Analyze display technology without backlights
Match the self-illuminating display technology to OLED panel.
Organic LED displays emit light per pixel and do not use cold cathode fluorescent lamps, LED backlight strips, or inverter boards.
