A systems administrator is reviewing hardware service guidelines for upgrading and maintaining a corporate fleet of laptops. Which of the following technical considerations regarding laptop hardware components and upgrades are accurate? (Select TWO.)
- Thin-and-light laptops often feature soldered LPDDR memory on the system board, which prevents post-purchase RAM upgrades.Cevap
- OLED laptop displays emit light directly from individual pixels, eliminating the need for a separate fluorescent backlight inverter board.Cevap
- CIf a laptop requires memory expansion, standard 288-pin desktop DIMM modules can be installed directly into internal expansion slots.
- DWhen an OLED laptop screen displays a dark image, replacing the display inverter board is the primary repair action to restore screen illumination.
Cevap
The accurate statements are that thin-and-light laptops often feature soldered LPDDR memory on the system board preventing RAM upgrades, and OLED laptop displays emit light directly per pixel without needing a separate backlight inverter board.
Soldered LPDDR RAM prevents physical memory replacement or expansion, which is standard in many thin laptop designs. OLED displays generate illumination at the pixel level and do not use backlights or backlight inverters.
