Docking Station Ethernet System: Bent Ethernet port contact | Auckland
Pattern to record: Link changes when the cable is reseated or one speed never negotiates.
Separate the adapter from the network
Dock Ethernet shares the dock’s host connection and power arrangement. Compare network-only use with displays and storage active, then distinguish a disappearing USB device from a live adapter with no Ethernet link. One possible explanation is that one spring contact no longer aligns with the cable plug.
Link and configuration checks
- Separate dock firmware, host USB-C link, power and the network side using controlled comparisons.
- Inspect all eight contacts and compare a known undamaged cable.
Before internal work
Use the dock's correct power supply during diagnosis. Probing a powered port with metal can short magnetics or power.
Verify the network path
If the checks support this cause, replace the connector or complete interface assembly. Verification should cover link speed, displays plus network load, sleep, undock, redock and restart.
For an assessment of your docked 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.
