Windows Stop Code 0x000000BD (INVALID_HIBERNATED_STATE): Causes and Troubleshooting

Quick Answer

Windows Stop Code 0x000000BD (INVALID_HIBERNATED_STATE) is a Blue Screen of Death (BSOD) error that occurs when Windows detects that the saved hibernation memory image does not match the computer's current hardware configuration.

According to Microsoft, this bug check can occur when a computer resumes from hibernation and Windows detects that the hardware configuration has changed while the system was hibernated. The documented parameter information specifically identifies a reduction in the number of installed processors as one condition.

The safest initial troubleshooting approach is to perform a complete restart, check for recent hardware or firmware changes, and investigate the hibernation configuration. If the error continues, examine the Windows crash dump and hardware configuration before attempting more advanced repairs.

1. What Is INVALID_HIBERNATED_STATE (0x000000BD)?

INVALID_HIBERNATED_STATE is a Windows kernel bug check, commonly known as a Blue Screen error or BSOD. Its hexadecimal bug check value is 0x000000BD.

Windows uses hibernation to save the current system state to a file on the storage drive so that the computer can restore its previous working state when it starts again.

During the resume process, Windows expects the saved hibernation information to be compatible with the computer's current hardware configuration. If the expected hardware state does not match the actual configuration, Windows can stop the resume operation and generate the INVALID_HIBERNATED_STATE bug check.

This error is associated with the Windows power-management and hibernation-resume process. It does not automatically indicate that the RAM, hard drive or processor is physically defective.

2. Understanding Windows Hibernation

Hibernation is a power-saving feature that allows Windows to preserve the system state when the computer is switched off.

When hibernation is activated:

1. Windows saves the required system memory contents to a hidden system file named hiberfil.sys.
2. The computer enters a low-power state and can be switched off without losing the saved session.
3. When the computer is powered on again, Windows reads the saved information and attempts to restore the previous system state.
4. Windows verifies that the saved state is compatible with the current hardware configuration before completing the resume process.

If the hardware configuration has changed in a way that makes the saved state invalid, Windows may generate a bug check.

Hibernation and Fast Startup

Windows also uses hibernation technology for Fast Startup. Fast Startup saves the Windows kernel session and device-driver state to the hibernation file during shutdown to reduce startup time.

Therefore, hibernation-related troubleshooting can also be relevant when an error occurs after shutting down and subsequently starting the computer, even if the user did not manually select Hibernate.

For additional technical information, refer to Microsoft's documentation on Windows system power states.

3. Causes of INVALID_HIBERNATED_STATE

Microsoft documents this bug check as a mismatch between the saved hibernation memory image and the current hardware configuration.

The following situations are relevant when investigating this error.

3.1 Hardware Configuration Changed During Hibernation

This is the documented condition associated with bug check 0x000000BD.

For example, if the hardware configuration changes while the computer is hibernated, the previously saved system state may no longer be compatible with the current configuration.

3.2 Processor Configuration Changed

Microsoft specifically documents a processor-count condition in the bug check parameters. If the number of installed processors is lower than it was before hibernation, Windows can identify this as an invalid hardware state.

Changes to processor availability or hardware configuration should therefore be investigated, particularly when they occur between hibernation and resume.

3.3 Hardware Replacement or Modification

Recent hardware maintenance can be relevant to the investigation. For example, consider whether the computer underwent motherboard or processor replacement, hardware servicing, or a configuration change while it was in a hibernated state.

These events are investigation points, not proof that a particular component caused the crash.

3.4 Firmware or BIOS Configuration Changes

BIOS or UEFI firmware controls important hardware initialization and configuration settings. Changes to processor-related settings or firmware configuration may be relevant when investigating a hardware-state mismatch.

However, Microsoft does not identify a particular BIOS setting or firmware version as a universal cause of this bug check.

3.5 Repeated Hibernation or Resume Failures

If the error occurs repeatedly, the saved hibernation state and the sequence of hardware configuration changes should be investigated.

Disabling and re-enabling hibernation can be used as a controlled troubleshooting test. It should not be treated as proof of the underlying hardware cause.

4. Symptoms of Error 0x000000BD

A computer experiencing INVALID_HIBERNATED_STATE may display one or more of the following symptoms:

• A Blue Screen of Death appears during startup or resume from hibernation.
• Windows unexpectedly restarts after attempting to restore a previous session.
• The computer fails to resume its previous working state.
• The system repeatedly crashes during a particular power-state transition.
• The error message displays the stop code INVALID_HIBERNATED_STATE.
• The blue screen displays the bug check value 0x000000BD.

The exact symptoms depend on the system configuration and the circumstances under which the failure occurs.

5. How to Troubleshoot INVALID_HIBERNATED_STATE

Follow the troubleshooting steps below in order. Begin with non-disruptive checks before changing power settings or firmware configuration.

Step 1: Perform a Complete Restart

If Windows successfully starts after the blue screen, perform a normal restart.

1. Save any open work.
2. Open the Start menu.
3. Select Power.
4. Select Restart.
5. Allow Windows to complete the restart process.
6. Check whether the system operates normally.

A restart performs a fresh Windows boot rather than restoring the previous hibernated session. This helps determine whether the problem is limited to restoring the saved state.

Important: If Windows cannot start normally, use the Windows Recovery Environment or Safe Mode as appropriate. Do not repeatedly force shutdowns if important data is at risk.

Step 2: Check for Recent Hardware Changes

Review whether any hardware changes were made before the error appeared.

Check the following:

• Was the processor recently replaced?
• Was the motherboard replaced or serviced?
• Were any hardware components added or removed?
• Were processor-related BIOS or UEFI settings changed?
• Did the problem begin immediately after hardware maintenance?

If new external hardware was connected recently, safely disconnect the non-essential device and test the computer again.

For internal hardware, use a qualified technician when inspection or replacement is necessary. Avoid removing or reseating processor-related components without appropriate technical knowledge.

Step 3: Check the Hibernation Configuration

Windows includes the powercfg command-line utility for managing power settings.

To inspect the available power states:

1. Press Windows + X.
2. Select Terminal (Admin) or Command Prompt (Admin), depending on the Windows version.
3. Approve the User Account Control prompt if displayed.
4. Execute the following command:

powercfg /a

This command displays the sleep states available on the computer and helps identify whether hibernation is supported and enabled.

Review the output before making any changes.

Step 4: Temporarily Disable Hibernation

If the computer continues to experience hibernation-related failures, temporarily disabling hibernation can help determine whether the problem is associated with the hibernation or Fast Startup path.

Warning: Disabling hibernation removes the ability to use standard hibernation and hybrid sleep. It also affects Fast Startup. Microsoft warns that making hibernation unavailable can result in data loss if power is lost while hybrid sleep is enabled.

Before proceeding, save your work and ensure that the computer is not relying on an active hibernated session.

1. Open Command Prompt or Windows Terminal as Administrator.
2. Execute the following command:

powercfg.exe /hibernate off

3. Wait for the command to complete.
4. Restart the computer.
5. Test the system under normal operating conditions.

This operation disables hibernation and removes the associated hibernation file managed by Windows. It is a diagnostic step, not a guaranteed repair for every instance of error 0x000000BD.

Step 5: Re-enable Hibernation After Testing

If you want to restore the hibernation feature after testing, open an elevated Command Prompt and execute:

powercfg.exe /hibernate on

After the command completes:

1. Restart Windows.
2. Run powercfg /a again.
3. Check whether hibernation is available.
4. Test hibernation and resume under normal conditions.

If the error returns after re-enabling hibernation, further investigation is necessary. Do not repeatedly toggle the feature without identifying the circumstances of the failure.

For official instructions, refer to Microsoft's guide: How to disable and re-enable hibernation.

Step 6: Review BIOS or UEFI Configuration

If the error appeared after a firmware update, BIOS configuration change or hardware replacement, investigate the firmware settings.

1. Restart the computer.
2. Enter the BIOS or UEFI setup using the manufacturer's designated key.
3. Review processor-related settings and any recently modified hardware configuration options.
4. Compare the current configuration with the manufacturer's recommended settings.
5. Save changes only when they are understood and appropriate.

Important: Do not randomly change BIOS settings or load default settings on a business-critical computer. Firmware changes can affect boot configuration, storage-controller settings, security features and operating-system startup.

If a BIOS update is necessary, obtain the correct firmware from the computer or motherboard manufacturer's official support website and follow its installation instructions.

Step 7: Check Device Drivers and Windows Updates

Although Microsoft documents 0x000000BD as a hardware-configuration and hibernation-state mismatch, driver and Windows maintenance can be useful when investigating repeated system crashes.

Perform the following checks:

1. Open Device Manager.
2. Check for devices displaying a warning symbol.
3. Review recently installed or updated hardware drivers.
4. Obtain appropriate drivers from the computer or component manufacturer's official website.
5. Check Windows Update for applicable updates.
6. Restart the computer after installing necessary updates.

Give particular attention to recent changes involving platform, chipset and power-management components when they are relevant to the system configuration.

Do not uninstall working drivers or install unrelated driver-update utilities merely because this stop code appeared.

Step 8: Analyze the Windows Crash Dump

If the error occurs repeatedly, analyzing the crash dump is a useful advanced diagnostic procedure.

Windows may create crash dump files containing information about the system state at the time of the bug check.

Common dump-file locations include:

• C:\Windows\Minidump\ - Small memory dump files, when configured and generated.
• C:\Windows\MEMORY.DMP - A memory dump file, when configured and generated.

To examine a dump file, an IT professional can use Microsoft's WinDbg debugger.

1. Install WinDbg using Microsoft's official distribution.
2. Open WinDbg.
3. Select File and then Open Dump File.
4. Browse to the relevant dump file.
5. Allow the debugger to load the required symbols and analyze the dump.
6. Execute the following command in the debugger:

!analyze -v

Review the bug check code, parameters and available diagnostic information.

For this specific error, the bug check parameters can help establish whether the documented processor-count condition was involved.

Dump analysis requires technical knowledge. A module name or driver appearing in a dump does not automatically prove that the component is defective.

Refer to Microsoft's documentation: Analyze a Kernel-Mode Dump File by Using WinDbg.

6. Understanding Bug Check Parameters

Microsoft documents four parameters for INVALID_HIBERNATED_STATE. These parameters provide additional information about the hardware condition associated with the bug check.

Parameter	Description
Parameter 1	Identifies the hardware condition that was invalid. A value of 1 indicates that the number of installed processors is lower than before hibernation.
Parameter 2	When Parameter 1 is 1, indicates the number of processors before hibernation.
Parameter 3	When Parameter 1 is 1, indicates the number of processors after hibernation.
Parameter 4	Reserved.

Example of Processor-Count Mismatch

Consider a hypothetical system with the following configuration:

• Number of processors before hibernation: 8
• Number of processors after hibernation: 4
• Parameter 1: 1
• Parameter 2: 8
• Parameter 3: 4

This example illustrates the documented processor-count mismatch condition. It does not mean that every INVALID_HIBERNATED_STATE crash has these parameter values.

For the complete parameter definitions, refer to Microsoft's official Bug Check 0xBD: INVALID_HIBERNATED_STATE documentation.

7. When Should You Contact Technical Support?

Professional technical assistance may be necessary when:

• The computer repeatedly crashes with the same stop code.
• The error started after motherboard or processor replacement.
• The system fails to start normally.
• BIOS or UEFI configuration changes do not resolve the issue.
• The crash dump indicates a more complex kernel or hardware problem.
• The computer is part of a business-critical environment.
• Important data or unsaved business operations may be at risk.

When contacting the computer manufacturer or an IT professional, provide the following information:

• Exact Windows version and build number.
• Computer manufacturer and model.
• Processor and motherboard details.
• Recent hardware or firmware changes.
• Whether the error occurs during hibernation, resume or normal startup.
• Bug check parameters, if available.
• Relevant Windows crash dump files.

This information can help narrow down the problem without unnecessary hardware replacement or operating-system reinstallation.

8. How to Prevent INVALID_HIBERNATED_STATE

The following practices can help reduce the risk of hibernation-related system failures:

• Complete a normal shutdown or restart before performing hardware maintenance.
• Avoid changing processor or motherboard configurations while the computer is in a hibernated state.
• Use manufacturer-approved BIOS and firmware updates.
• Maintain compatible and supported device drivers.
• Investigate repeated resume failures instead of repeatedly forcing the computer to restart.
• Keep important business data backed up.
• Document hardware and firmware changes in business environments.
• Test hibernation and resume after significant hardware maintenance.

For computers used in business-critical environments, administrators should evaluate whether hibernation is appropriate for their hardware and operational requirements.

9. Frequently Asked Questions

What does Windows error 0x000000BD mean?

Error 0x000000BD means Windows detected an invalid hibernated state. The saved hibernation memory image does not match the current hardware configuration, preventing Windows from safely restoring the previous system state.

Is INVALID_HIBERNATED_STATE a hardware or software problem?

The documented bug check is related to a mismatch between the saved hibernation image and the current hardware configuration. However, the stop code alone does not establish whether a physical component is defective. The actual circumstances and crash-dump information must be examined.

Can disabling hibernation fix error 0x000000BD?

Temporarily disabling hibernation using powercfg /hibernate off can help determine whether the problem is associated with the hibernation or Fast Startup path. However, this is a diagnostic measure and is not a guaranteed solution for every cause of the error.

Does INVALID_HIBERNATED_STATE mean that RAM is faulty?

No. This error does not automatically indicate defective RAM. Microsoft specifically describes a mismatch involving the saved hibernation image and hardware configuration. Memory diagnostics may be appropriate if additional evidence indicates a memory-related problem.

Can Fast Startup be related to this error?

Yes, Fast Startup uses hibernation technology to preserve the Windows kernel session and device-driver state during shutdown. Therefore, investigating Fast Startup may be relevant when the error occurs after a shutdown and subsequent startup.

Will updating the BIOS fix INVALID_HIBERNATED_STATE?

Not necessarily. A BIOS update may be relevant if the problem is associated with firmware or hardware configuration changes, but Microsoft does not document a BIOS update as a universal solution. Update firmware only when there is a relevant manufacturer recommendation or a clearly identified compatibility issue.

Is reinstalling Windows necessary to fix error 0x000000BD?

Usually, reinstalling Windows should not be the first troubleshooting step. Start by investigating hardware changes, hibernation configuration, firmware settings and crash-dump information. Reinstallation should only be considered when there is sufficient evidence that Windows installation damage is involved and less disruptive recovery options are unsuitable.

Where can I find the Windows crash dump file?

When configured and successfully generated, small memory dumps are generally stored in C:\Windows\Minidump\, while a system memory dump may be stored as C:\Windows\MEMORY.DMP.
