A field technician is preparing to replace a failed internal M.2 NVMe SSD in an enterprise laptop. Arrange the technician's procedure steps in the correct chronological order from first to last.
- 1Shut down the operating system completely and unplug the AC power adapter from the laptop.
- 2Remove the bottom enclosure retaining screws and carefully detach the access panel.
- 3Disconnect the internal battery cable connector from the motherboard socket.
- 4Unscrew the M.2 drive retaining fastener, pull out the faulty SSD, insert the replacement SSD, and secure it.
- 5Plug the internal battery connector back into the motherboard, reattach the enclosure cover, and secure the screws.
Answer
The proper sequence is: 1) Shut down the operating system and unplug the AC power adapter, 2) Remove the bottom enclosure screws and detach the access panel, 3) Disconnect the internal battery cable from the motherboard, 4) Replace the M.2 SSD module and tighten the retaining screw, and 5) Reconnect the internal battery, reinstall the bottom cover, and secure the chassis screws.
Standard CompTIA hardware service safety dictates isolating external power first by shutting down the laptop and removing the AC adapter, removing the back panel to access internals, disconnecting the internal battery cable from the motherboard to eliminate standby voltage, swapping and securing the M.2 SSD, and finally reconnecting internal power and securing the chassis cover before powering on the laptop.
