Start with the pattern, not a guess
Charging failure can originate at the wall outlet, power adapter, cable, charging port, internal power circuitry, battery, or firmware. Record which indicator lights appear and whether the connector feels loose, but do not keep flexing the plug. A swollen battery, unusual heat, odor, or case separation changes this from troubleshooting to an immediate power-down decision.
Practical checks and decisions
Work from observation to one controlled change at a time. Stop when the next step could risk data, accounts, electrical safety, or additional hardware damage.
Test a known-good outlet and inspect the adapter
Record the exact model, charger, indicator lights, battery behavior, temperature, and whether the symptom changes when the lid or connector moves. Model-specific construction and parts affect the repair path.
Look for looseness, heat, smell, or visible port damage
Use one known-good outlet and the correct compatible adapter when it is safe. Do not keep flexing a loose charging plug or hinge; movement that briefly restores operation is useful evidence of physical damage.
Stop using a swollen battery
Power down immediately for battery swelling, unusual heat, odor, liquid, exposed glass, or case separation. Do not press a swollen case closed or continue charging to see whether it improves.
Use a correct compatible charger for testing
Protect important files before resets, storage work, or repeated startup attempts. Compare the complete repair—including parts and hidden-damage risk—with a suitable replacement.
When a professional diagnosis makes sense
Arrange diagnosis when charging, display, hinge, heat, battery, or startup symptoms return; when the case or battery is physically unsafe; or when model-specific parts and hidden damage must be evaluated. Bring the correct power adapter and the exact model information.
