Difficulty: MediumLaptop Hardware Components and Upgrades

Match each laptop internal hardware component with its correct description or key installation characteristic.

  • SODIMM ModuleCompact memory module designed for mobile systems with physical notch locations distinct from desktop DIMM form factors.
  • CCFL Inverter BoardConverts low-voltage DC system power into high-voltage AC to power cold-cathode fluorescent backlights in older laptop displays.
  • WWAN Expansion CardInternal cellular adapter requiring connection to integrated antenna wires routed through the laptop display hinge frame.
  • M.2 NVMe DriveProvides high-speed internal solid-state storage inserted into a keyed slot at a 30-degree angle and secured with a single screw.

Answer

SODIMM Module matches with compact memory for laptops with distinct pin notches; CCFL Inverter Board matches with converting low-voltage DC to high-voltage AC for older backlights; WWAN Expansion Card matches with cellular network adapters connected to display antenna wires; M.2 NVMe Drive matches with high-speed storage inserted into a keyed slot at an angle and secured with a screw.
Each component is correctly matched based on its primary function and installation requirements: SODIMM modules provide compact RAM; inverter boards convert DC to AC for legacy CCFL displays; WWAN cards connect to internal display antennas for cellular signal; and M.2 NVMe drives provide compact PCIe storage inserted at an angle and fastened with a single screw.

Step-by-Step Solution

1
Identify memory form factor requirements for laptops.
SODIMM modules are identified as laptop-specific RAM with specialized pin counts and notch placements.
Laptops use small-outline dual in-line memory modules (SODIMMs) rather than full-sized desktop DIMMs.
2
Analyze display power conversion components.
The CCFL inverter board is identified as responsible for DC-to-AC conversion.
Legacy CCFL backlights require high-voltage AC power derived from the laptop's lower-voltage DC system.
3
Determine wireless expansion card requirements.
WWAN expansion cards pair with internal antenna connections routed around the screen.
Cellular communication requires dedicated antenna leads positioned high up in the display frame for optimal signal strength.
4
Evaluate internal storage form factors and installation steps.
M.2 NVMe drives match the description of angled insertion into a keyed M-slot secured by a screw.
M.2 drives use a standardized insertion angle (approx. 30 degrees) and a single fastener.
