DIAGNOSTIC WALKTHROUGHS

What changes the repair decision

Illustrative technical scenarios show how measurements and platform checks guide the next step. They demonstrate repair logic and are not presented as completed Tokdraw customer jobs.

EXAMPLE 01 · H100

A GPU that does not initialize

  1. 01

    Reported behavior

    A compatible host does not detect the module, with no obvious external damage.

  2. 02

    Assessment & repair option

    Electrical findings may identify a localized power fault. A confirmed component failure can support targeted replacement.

  3. 03

    Validation

    Repeat recognition, functional and load tests in a compatible configuration.

The symptom alone does not establish a failed GPU core.

EXAMPLE 02 · A100

A timeout with several possible causes

  1. 01

    Reported behavior

    Device queries or workloads time out.

  2. 02

    Assessment & repair option

    Compare logs, power, cooling and software conditions. Confirmed findings determine the repair or configuration change.

  3. 03

    Validation

    Repeat the affected query or workload and record whether the timeout returns.

A timeout can have several causes; repeatable evidence guides the next step.

EXAMPLE 03 · PCIe CARD

A damaged card edge

  1. 01

    Inspect the damage

    Review contacts, pads and surrounding board material.

  2. 02

    Compare repair options

    Accessible damage may support local repair. Deeper damage may require PCB replacement and component-transfer assessment.

  3. 03

    Confirm feasibility

    Review component condition, replacement-board compatibility and the validation plan.

A replacement PCB does not establish that the original GPU and memory are usable.
