A field technician is replacing a swollen internal Lithium-ion battery and a damaged internal DC power jack inside an enterprise laptop. Which TWO of the following actions should the technician take to perform this repair safely and correctly?
- Disconnect the external AC power adapter and disable or disconnect the battery before handling internal components.Cevap
- BFully drain the swollen battery to 0% using a continuous hardware stress test prior to removal to calibrate the chemical cells.
- Carefully route internal power wiring along chassis cable guides to prevent wire pinching when securing the bottom panel.Cevap
- DUpgrade the laptop system memory using standard 288-pin desktop DIMM modules while the chassis is open.
Cevap
The technician must disconnect the AC power adapter and internal battery before handling hardware, and route internal cabling cleanly along designated chassis channels to prevent pinching during reassembly.
Servicing internal laptop components safely requires removing all power sources (external AC power and the internal battery) to avoid electrical short circuits. Additionally, internal power wiring must be routed cleanly through chassis channels to prevent pinched or cut wires during reassembly.
