A field technician needs to safely replace an internal SODIMM memory module in a corporate laptop. Place the following hardware upgrade procedure steps in the correct order from first to last.
- 1Disconnect the external AC power adapter and perform a complete operating system shutdown.
- 2Remove the lower chassis enclosure screws and detach the bottom access panel.
- 3Disconnect the internal battery connector from the motherboard.
- 4Spread the side retaining metal clips outward to pop the existing SODIMM module up to a 45-degree angle and slide it out.
- 5Align the key notch, insert the new SODIMM module into the slot at a 45-degree angle, and push down until the side clips lock into place.
Answer
The correct order begins with disconnecting external power and shutting down the OS, followed by removing the chassis cover, disconnecting the internal battery, removing the old SODIMM at a 45-degree angle after releasing the clips, and finally inserting the new SODIMM at an angle and locking it down.
The proper sequence follows standard CompTIA hardware maintenance protocols: first isolate external AC power and shut down the device, remove the lower enclosure, disconnect the internal battery to eliminate residual voltage, release and tilt the existing SODIMM module out of its socket, and insert the new SODIMM at a 45-degree angle before locking it flat into the retaining latches.
