A field technician needs to replace an internal M.2 NVMe solid-state drive (SSD) in a thin-and-light corporate laptop equipped with a non-removable internal battery. In what sequence should the technician perform the hardware replacement procedure to ensure safety, ESD protection, and successful component installation?
- 1Disconnect the external AC power adapter and execute a full operating system shutdown.
- 2Remove the bottom enclosure screws, open the chassis, and attach an ESD wrist strap to a grounded surface.
- 3Disconnect the main internal battery cable connector from the system board.
- 4Remove the existing drive screw, insert the replacement M.2 SSD at a 30-degree angle into the drive key slot, and secure the drive retaining screw.
- 5Reconnect the internal battery cable, reattach the bottom chassis cover, and boot into UEFI/BIOS setup to verify drive detection.
Cevap
The correct service sequence begins with turning off power and removing the AC adapter, followed by opening the chassis and equipping ESD protection. Next, the internal battery cable must be disconnected from the motherboard before physically replacing the M.2 SSD module. Finally, reconnect the internal battery, assemble the chassis, and confirm drive detection in UEFI/BIOS.
Safe technician hardware procedures dictate completely isolating power sources first (AC power followed by internal battery connection) and establishing ESD grounding before touching sensitive internal components like M.2 NVMe SSDs. The drive must be installed mechanically at its designated angle before internal power is reconnected and system firmware detection is verified.
