Business 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

Record the office network, dock state and authentication message. Compare only authorised networks and leave managed security settings in place.

Stop point: Preserve managed-network and encryption settings during diagnosis.

Workshop confirmation and repair

Device-level check: Compare another approved network, direct and docked use, power state and authentication behaviour.

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 configuration, antenna, module or driver path without weakening security.

Related cause to rule out

Checks after the work

After repair or replacement, check office network, hotspot, meetings traffic, dock transition and sleep.
