Closest known fix
Written by AI from what people tried. Nobody has confirmed it works yet.
These reports don't share one cause, so there's no single guaranteed fix. Try these in order, starting with the cheapest:
1. **Reset the embedded controller.** Shut down, unplug the charger, and remove the battery if you can. Hold the power button for 30 seconds, then reconnect the battery and charger and boot.
2. **Test your charger.** Use the original adapter, or one with the same wattage, and check the cable and port for damage or looseness.
3. **Update the BIOS** from your manufacturer's support site. Many power and charging bugs are fixed this way.
4. **Recalibrate the battery.**
