Windows Laptop 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

Write down the exact screen or error reached at startup and the last update or software change. Confirm whether important files are backed up before considering recovery tools.

Stop point: Forced restarts and reinstall attempts can place data at risk.

Workshop confirmation and repair

Device-level check: Separate firmware, recovery, safe-mode and user-account behaviour while protecting local files.

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 only the affected Windows layer after storage and hardware health are checked.

Related cause to rule out

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

Checks after the work

After repair or replacement, check cold boot, sign-in, updates, devices, sleep and shutdown.
