All-in-One Computer 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 distance from the access point and time since startup. Compare another device at the same location before attributing weak reception to the computer.

Stop point: All-in-one housings may contain mains-power sections and should be opened safely.

Workshop confirmation and repair

Device-level check: Compare distance, bands, temperature, driver state and a known external adapter.

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 module, antenna, software or board path confirmed by comparison.

Related cause to rule out

When the adapter shows an error or vanishes after Windows loads, also consider All-in-One Computer 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, restart and warm operation.
