Zorluk: Çok zorLaptop Hardware Components and Upgrades

A field technician is servicing several enterprise laptops to upgrade internal hardware and service display and power components. During hardware inspection and pre-upgrade evaluation, which of the following statements correctly describe the hardware compatibility, design characteristics, and safety procedures required for these laptop servicing operations? (Select TWO.)

  1. Laptop memory upgrades require Small Outline Dual In-line Memory Modules (SO-DIMMs) due to the restricted physical clearance of laptop expansion slots.Cevap
  2. Both the external AC power adapter and the internal primary battery must be completely disconnected before accessing internal motherboard components.Cevap
  3. C
    Standard full-sized desktop DIMM memory modules can be installed into laptop expansion bays as long as the memory bus clock speeds match.
  4. D
    Upgrading a laptop to an organic light-emitting diode (OLED) display panel requires installing an integrated high-voltage display inverter board.

Cevap

The correct statements are that laptop memory upgrades require SO-DIMM modules due to physical form factor constraints, and all power sources (both external AC power and internal batteries) must be completely disconnected before accessing internal motherboard components.
Laptop hardware upgrades require SO-DIMM form-factor modules because space constraints prevent the use of standard desktop DIMMs. Additionally, disconnecting both the AC adapter and internal battery before disassembling the unit ensures the system is completely depowered, eliminating the risk of electrical shorting or component damage during hardware installation.

Adım Adım Çözüm

1
Analyze RAM physical form factor requirements for laptops.
Laptops require SO-DIMM memory modules because standard desktop DIMM modules are physically too large to fit in laptop chassis.
Compact mobile hardware uses standardized SO-DIMM architecture.
2
Determine safety precautions prior to opening laptop chassis.
Disconnect both external power supplies and internal batteries.
Residual power on the motherboard can short sensitive components when replacing parts.
3
Evaluate display technology power mechanisms.
Recognize that OLED screens do not use high-voltage inverters.
OLED pixels produce their own light directly, eliminating the need for cold-cathode fluorescent lamp (CCFL) backlight inverters.
