A field technician is servicing an enterprise laptop to replace a failing internal M.2 NVMe solid-state drive (SSD). Place the technician's repair steps in the correct sequence from first to last.
- 1Completely power off the laptop and disconnect the AC power adapter.
- 2Remove the bottom base cover screws and carefully detach the chassis cover.
- 3Disconnect the internal battery cable from the motherboard connector.
- 4Remove the M.2 drive retaining screw, swap the drive, and re-secure the screw.
- 5Reconnect the internal battery connector and reinstall the bottom chassis cover.
Cevap
The correct sequence is: Completely power off the laptop and disconnect the AC power adapter, followed by removing the bottom base cover, disconnecting the internal battery cable from the motherboard, removing and replacing the M.2 drive, and finally reconnecting the internal battery cable and reinstalling the chassis cover.
Safe laptop hardware servicing requires eliminating all power sources before touching sensitive internal circuitry. Disconnecting external AC power comes first, followed by opening the chassis to disconnect the internal battery cable. Once internal power is isolated, the M.2 drive can be safely unfastened and replaced. Finally, the battery is reconnected and the enclosure is fastened back together.
