Before You Touch the Device
- Write down the device model, charger type, and the exact symptom.
- Note whether the issue began after a drop, liquid exposure, heat event, update, or battery swell.
- Back up important files first when the device still powers on safely.
Low-Risk First Checks
- Test the power source, outlet, charger, or cable before opening the device.
- Look for loose connectors, dirt, broken plugs, or obvious settings mistakes.
- Check for simple pattern clues such as no sound on every input, only on Bluetooth, or only when the battery is low.
- Use the shortest test that confirms the next decision instead of repeating the same trial.
Stop Immediately If You See These
- Swelling, smoke, spark, burning smell, or unusual heat.
- Liquid residue, corrosion, or repeated short power cycles.
- A repair path that now needs soldering, board probing, or battery removal you cannot control safely.
What to Bring Into a Diagnostic Request
- The model name and any known storage or battery history.
- What you already tested and what changed the symptom.
- Whether the device contains important school, work, or customer files.
