ERROR_GRAPHICS_CHAINLINKS_NOT_POWERED_ON

Interpret the result in its owning layer: graphics chainlinks not powered on

The useful interpretation of ERROR_GRAPHICS_CHAINLINKS_NOT_POWERED_ON (0xC0262435) starts at the linked boundary: the lead was powered while one or more chain members remained in a low-power state. In practical terms, inspect linked-adapter power ordering before changing application-wide graphics settings.

Capture before recreating objects

Capture itemWhy it matters
Object identitylinked-adapter power ordering
Rejected conditionthe lead was powered while one or more chain members remained in a low-power state
What to captureDx power state per member, resume order, power IRPs and lead operation
Current graph statelead adapter, chain members and their PnP/power transitions
Supporting tracedevice-instance IDs, lead/chain role, PnP problem codes, Dx states and start/power IRP ordering

Reproduce one variable at a time

  1. Resume the chain members first and repeat the lead power-up.

The comparison with ERROR_GRAPHICS_CHAINLINKS_NOT_STARTED is especially useful: ERROR_GRAPHICS_CHAINLINKS_NOT_STARTED concerns PnP start, not device power.

Recovery contract

Coordinate power transitions across the linked set and handle partial-resume rollback.

  • debug-layer, ETW or driver diagnostics no longer report the rejected linked-adapter power ordering contract during the same scenario.
