Capture the full fault context
Record the full app or on-device code and message, the active task, dock state and recent maintenance. Do not search a bare number and transfer an answer across models.
Use only low-risk official steps
Check power, placement, visible obstruction, cleanable sensors and charging contacts in the official order, retesting after each step. Do not repeatedly reset at random or open the device.
When to escalate
Stop and contact the manufacturer when an alert repeats, odor or abnormal heat appears, charging parts are damaged, liquid ingress is possible, or the official steps do not work.
Where the evidence stops
If the official source does not explicitly cover the full model, sales region, dock variant or accessory SKU, keep the result Unknown and ask the manufacturer with the exact label information.
- Do not infer compatibility from appearance.
- Do not transfer electrical or warranty rules across regions.
- Do not perform steps that open the battery or dock electronics.
