I. Warranty Period

The following situations are covered under normal use conditions:

• The main hardware of the product fails due to non‑human factors.
• The device fails to start normally and the failure is confirmed to be hardware‑related.
• Quality issues of core components such as chips, mainboards, or fans under normal operation.
• Other faults confirmed by StarMiner after‑sales as product‑quality related.

III. Exclusions (Not Covered by Warranty)

The following situations are NOT covered by the free warranty service:

• Products exceeding the 6‑month warranty period.

• During repair, components may be replaced with equivalent or similar performing parts.
• Replaced parts become the property of StarMiner.
• If the product cannot be repaired, StarMiner may offer a replacement of the same model or of equivalent value.

• Use the original power adapter or a certified equivalent that meets the specifications.
• Keep the device in a well‑ventilated area, away from high temperature, humidity, and dust.
