All-in-One PC Windows System: power-management state fault. A driver or firmware component fails to restore hardware after low power.

The distinguishing clue

The problem appears after sleep and clears only after full shutdown.

Checks before an assessment

Note whether the built-in display, camera and audio fail together or whether Windows itself stops loading. Remove only nonessential external accessories with the computer shut down.

Stop point: All-in-one hardware can contain mains-power sections, so software diagnosis should precede opening.

Workshop confirmation and repair

Device-level check: Compare firmware, recovery, another account and external peripherals before opening the display housing.

Targeted check: Compare restart, full power removal and sleep while reviewing wake events. If confirmed: Update or reconfigure the confirmed power-management component.

Repair boundary: Repair the confirmed software layer after internal hardware and storage checks agree.

Related cause to rule out

When controls vanish even though the device and driver are present, also consider All-in-One PC Windows System: disabled system service before choosing a repair.

Checks after the work

After repair or replacement, check startup, display, camera, audio, updates, sleep and shutdown.
