Motherboard Power System: damaged socket or pin. A bent contact prevents one processor, memory or peripheral signal from connecting.

The distinguishing clue

One channel or function fails after part removal or impact.

Checks before an assessment

Record existing lights, sounds and the point where startup stops. Keep the device off if there is liquid exposure, burning smell or repeated protection shutdown.

Stop point: Random voltage injection can destroy connected chips and stored data.

Workshop confirmation and repair

Device-level check: Isolate loads and measure resistance, enable signals and voltage sequence with controlled equipment.

Targeted check: Inspect alignment and compare the exact failure with pin function. If confirmed: Repair only where reliable contact can be restored; otherwise replace the socket or board.

Repair boundary: Repair the confirmed short, open circuit, regulator or sequencing stage.

Related cause to rule out

When the system is stable with the original part but not the replacement, also consider Motherboard Power System: hardware compatibility mismatch before choosing a repair.

Checks after the work

After repair or replacement, check standby draw, startup sequence, full load and temperature.
