A field technician is preparing to perform hardware upgrades and routine maintenance on several corporate laptops. Which TWO of the following statements correctly describe laptop hardware component specifications and replacement requirements?
- SO-DIMM modules must be specified for internal memory upgrades due to their compact form factor compared to desktop DIMMs.Cevap
- OLED display panels do not require a separate backlight inverter board because individual pixels emit their own light.Cevap
- CFull-sized desktop DIMM modules can be installed into modern laptop expansion slots if low-profile heat spreaders are used.
- DOLED laptop screens require a high-voltage CCFL inverter board to illuminate the display background.
Cevap
The correct statements are that SO-DIMM modules are required for laptop memory upgrades due to form factor constraints, and OLED display panels do not use backlight inverter boards because OLED pixels emit their own light.
Laptops strictly require SO-DIMM memory modules because their physical footprint is approximately half the length of standard desktop DIMMs. Additionally, OLED displays feature self-emissive pixels, eliminating the need for CCFL backlights and high-voltage inverter boards commonly associated with older LCD panels.
