A+ laptop hardware replacement: safe first steps
Before opening a laptop, identify its exact model and service procedure. Shut it down, remove external power, and disconnect the internal battery at the point specified by the manufacturer. Small ribbon connectors and antenna sockets can be damaged by force. Photograph or label connections, use appropriate ESD precautions, and check whether RAM or storage is actually replaceable before ordering parts.
How to read the scenario
Separate a compatibility question from a fault diagnosis. A soldered component is not upgraded by purchasing a larger removable module.
Identify the required outcome, the evidence already provided, and the limits on the technician’s action. Compare every option against those details before deciding. Record why the closest alternative does not meet the stated need.
