Difficulty: MediumLaptop Hardware Components and Upgrades

Match each laptop hardware servicing scenario on the left with the correct internal component or module required on the right.

  • Expanding system memory on a laptop requiring a compact form-factor memory module.SODIMM (Small Outline Dual In-line Memory Module)
  • Restoring power to a CCFL backlight on an older LCD panel showing a faint screen image.Display Inverter Board
  • Installing a high-speed internal solid-state drive directly into a motherboard key slot.M.2 NVMe Solid-State Drive
  • Upgrading internal WLAN connectivity using an expansion slot connected to antenna leads.M.2 / Mini PCIe Wi-Fi Card

Answer

Expanding system memory matches SODIMM; restoring power to CCFL backlight matches Display Inverter Board; installing high-speed SSD directly to motherboard matches M.2 NVMe Solid-State Drive; upgrading internal WLAN matches M.2 / Mini PCIe Wi-Fi Card.
Each laptop hardware scenario correctly maps to its respective component: SODIMMs provide compact system memory, display inverters convert DC to AC power for legacy CCFL LCD backlights, M.2 NVMe SSDs provide compact direct-attached storage, and internal M.2/Mini PCIe cards interface with wireless antenna leads for network connectivity.

Step-by-Step Solution

1
Identify memory module form factors for mobile hardware.
Laptops use SODIMM modules rather than full-size desktop DIMM modules.
Compact chassis design requires smaller footprint RAM modules.
2
Analyze display lighting failure symptoms.
Faint image visible with external light indicates missing backlight power provided by the display inverter on CCFL-based LCD screens.
The inverter supplies AC power to CCFL tubes; failure leaves the LCD matrix operational but unlit.
3
Select appropriate high-speed direct motherboard storage.
M.2 NVMe drives plug directly into M.2 slots for high performance.
M.2 form factor eliminates SATA data and power cabling.
4
Identify wireless adapter expansion interfaces.
Internal Wi-Fi adapters use M.2 or Mini PCIe form factors connected to antenna cables.
Provides modular Wi-Fi upgrading within internal chassis slots.
