ERROR_ABANDON_HIBERFILE

windows invalidated a hibernation file and will no longer use it for resume.

ERROR_ABANDON_HIBERFILE indicates this condition: The saved hibernation image failed a validity check or no longer matches the machine state closely enough for safe restoration. Windows therefore abandons the file and continues with a normal boot or another recovery path.

Where the result appears

  • boot diagnostics after an unsuccessful hibernate or fast-startup resume.
  • firmware or boot configuration changes made while a hibernation image existed.
  • disk, encryption, or storage-layout changes that invalidate the saved image.
  • power-loss recovery where the hiberfile contents are incomplete.

What to collect

  • the preceding Kernel-Boot and Kernel-Power events.
  • whether firmware, memory, storage, BitLocker, or boot configuration changed.
  • free space and health of the system volume.
  • the sleep transition that created the image and the next boot identifier.

Handling and recovery

Allow Windows to discard the invalid image and boot normally. If the event repeats, disable and re-enable hibernation to recreate the file, verify system-volume health and capacity, and update storage or firmware components implicated in resume failures.

Common misinterpretation

Abandoning the hiberfile does not mean user files were deleted. The lost state is the saved memory image; unsaved application work may be affected, but ordinary disk files are separate.
