Fix Stop 0xA0 After Resuming Windows 8 from Hibernate (Historical)

Historical support note: Windows 8 is out of support. This article documents a specific Microsoft-confirmed Windows 8 hibernation issue from 2013.

A blue screen with STOP 0x000000A0 is INTERNAL_POWER_ERROR. Microsoft defines it as a fatal error in the power policy manager.

Importantly, Microsoft also documented one specific Windows 8/Windows Server 2012 hibernate-resume problem that produced 0xA0.

Microsoft-documented Windows 8 scenario

The documented scenario involved a Windows 8/Server 2012 system with high-performance disks combined with a low-performance or single-core processor. The crash occurred when resuming from hibernation (S4).

Microsoft’s resolution for that specific issue was the Windows 8 and Windows Server 2012 cumulative update 2822241 (April 2013).

Not every 0xA0 crash is caused by that defect. The stop-code parameters matter.

If the documented update does not match your case

For a different 0xA0 pattern:

1. Note whether the crash occurs only after hibernate or also after sleep/shutdown.
2. Update chipset, storage/AHCI, graphics, and power-management drivers from the PC manufacturer.
3. Check the manufacturer’s firmware/BIOS release notes for resume or power fixes.
4. Review the crash dump to identify the 0xA0 parameter values.

The original article advised enabling the S4 state in BIOS as a generic fix. Do not change firmware power-state settings blindly; use the hardware manufacturer’s documented configuration.
