Laptop Memory System: hardware compatibility mismatch. A part fits but its electrical specification or firmware support differs.

The distinguishing clue

The system is stable with the original part but not the replacement.

Checks before an assessment

Record the reported memory capacity, diagnostic code and last memory upgrade. Keep files protected and avoid repeated crashes to demonstrate the problem.

Stop point: Memory should be handled with all power removed and electrostatic precautions.

Workshop confirmation and repair

Device-level check: Test supported modules and channels in a controlled order while inspecting seating and firmware settings.

Targeted check: Compare supported revisions, capacity, timings and power requirements. If confirmed: Install a supported component and restore approved configuration.

Repair boundary: Repair the confirmed module, slot, channel or supporting board path.

Checks after the work

After repair or replacement, check cold boot, full memory test, sleep and restart.
