Windows Desktop 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

Record whether the PC stops before the Windows logo, during sign-in or after the desktop appears. This separates an operating-system symptom from failure to complete hardware startup.

Stop point: Disconnecting power during updates can corrupt system files.

Workshop confirmation and repair

Device-level check: Compare minimum hardware, safe mode, another account and event history before reinstalling Windows.

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 boot, driver, service or profile layer without erasing recoverable data.

Related cause to rule out

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

Checks after the work

After repair or replacement, check cold boot, user accounts, peripherals, updates and sustained desktop use.
