All-in-One Computer Ethernet Interface: Network driver power-state fault | Auckland
Pattern to record: Network works after restart but disappears after sleep or undocking.
Separate the adapter from the network
Identify whether Ethernet is built into the all-in-one or supplied through an external adapter. Compare the rear connector with a known cable and switch port before opening the display assembly. One possible explanation is that the adapter does not resume correctly from a low-power state.
Link and configuration checks
- Compare link before Windows loads, inspect the rear port and test another switch connection.
- Compare driver history, power settings and cold versus resumed operation.
Before internal work
All-in-one internal mains sections require trained handling. Disabling every power feature can reduce battery life without fixing firmware.
Verify the network path
If the checks support this cause, install the correct stable driver or firmware and adjust only supported power settings. Verification should cover link speed, sustained traffic, camera or video workload, sleep and restart.
