Laptop Wi-Fi System: network power-state lockup. The adapter fails to resume after sleep or aggressive power saving.

The distinguishing clue

Connectivity returns after full shutdown but fails again after standby.

Checks before an assessment

Compare another authorised network and record whether the adapter disappears or merely loses connection. Keep the router, distance and task unchanged when comparing results.

Stop point: Antenna plugs are delicate and the battery should be isolated before handling them.

Workshop confirmation and repair

Device-level check: Compare firmware detection, another network and sustained traffic before replacing hardware.

Targeted check: Compare sleep states and review adapter power-management settings. If confirmed: Correct the driver, firmware or power policy causing the lockup.

Repair boundary: Repair the confirmed driver, antenna, module or board path.

Related cause to rule out

When the adapter shows an error or vanishes after Windows loads, also consider Laptop Wi-Fi System: network driver corruption before choosing a repair.

Checks after the work

After repair or replacement, check both Wi-Fi bands, sustained transfer, roaming and sleep.
