Code 54: This device has failed and is undergoing a reset

Microsoft describes Code 54 as an intermittent ACPI reset state; if the reset never completes the device can remain stuck.

First action

Restart the computer if the device does not recover.

Use the error code as a Windows device-state clue. It does not by itself identify the exact failed component inside the hardware.

Then verify

Do not stop at the code disappearing

  1. 1

    Check whether the code clears after restart.

  2. 2

    If it repeatedly returns, investigate the device/firmware/driver with official support.

After Windows reports the device normally, run the matching DeviceOK test when one exists—for example camera, microphone, keyboard, mouse, controller or audio—to confirm the user-facing function works.
