Laptop Memory System: shorted board rail. A capacitor or semiconductor pulls a supply toward ground.

The distinguishing clue

Current draw is abnormal and protection may stop startup.

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: Isolate loads and locate the affected rail using controlled measurements. If confirmed: Replace the shorted component and verify resistance before power.

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

Related cause to rule out

When fans or lights start but the board never completes initialisation, also consider Laptop Memory System: incorrect power sequence before choosing a repair.

Checks after the work

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