Difficulty: MediumLaptop Hardware Components and Upgrades

A field technician is preparing to upgrade the system memory and service internal hardware on an enterprise laptop. Which of the following specifications and procedures correctly applies to servicing this laptop's internal hardware?

  1. Install SO-DIMM memory modules into the internal expansion slots after disconnecting the power source.Answer
  2. B
    Install standard full-sized DIMM memory modules into the motherboard expansion slots.
  3. C
    Replace the high-voltage backlight inverter board when servicing the integrated OLED display panel.
  4. D
    Perform several complete zero-percent deep discharge cycles on the Lithium-ion battery prior to hardware removal.

Answer

Install SO-DIMM memory modules into the internal expansion slots after disconnecting the power source.
The correct action is to install SO-DIMM memory modules after removing power sources. Laptop computers utilize SO-DIMMs due to tight space requirements, and disconnecting power (AC adapter and battery) prevents accidental short circuits during maintenance.

Step-by-Step Solution

1
Identify the proper form factor for laptop RAM expansion.
Laptops require SO-DIMM (Small Outline DIMM) modules rather than full-sized desktop DIMMs.
Compact mobile motherboard designs demand a smaller physical RAM footprint.
2
Verify safety measures before handling internal components.
Disconnect external AC power and the internal battery prior to touching components.
Prevents electrical shorts and damage to sensitive microelectronics during maintenance.
