Pattern to record: Power appears only at one plug angle and the centre contact feels abnormal.

Identify the input design

A gaming laptop may run normally at the desktop yet exceed the available adapter power during a combined CPU and GPU workload. Record the original adapter model and whether the failure occurs while gaming, charging, or both. One possible explanation is that the current-carrying pin is cracked internally or separated from its solder joint; this check applies only when the model actually uses a barrel connector with that contact arrangement.

Stop before further damage

Do not continue a graphics load when the plug, jack or cable is overheating. Bridging a broken pin can create a direct short.

Workshop checks

1. Use the correct wattage adapter, monitor input stability under a controlled load and inspect the jack and cable for heat damage.
2. Inspect the pin under magnification and check continuity without powering the device.

Repair and power verification

If the checks support this cause, replace the damaged jack or connector assembly with the exact supported part. Verification should cover idle charging, combined processor and graphics load, connector temperature and restart.

For an assessment of your gaming laptop, contact AEPC in Burswood or call 027 908 8880. Provide the model and the conditions that reproduce this problem. Workshop visits are by appointment.
