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.)
- Laptop memory upgrades require Small Outline Dual In-line Memory Modules (SO-DIMMs) due to the restricted physical clearance of laptop expansion slots.Cevap
- Both the external AC power adapter and the internal primary battery must be completely disconnected before accessing internal motherboard components.Cevap
- CStandard full-sized desktop DIMM memory modules can be installed into laptop expansion bays as long as the memory bus clock speeds match.
- DUpgrading 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.
