Shut down the laptop completely.
- Disconnect the charger and any connected accessories.
- Press and hold the power button for 20–30 seconds.
Reconnect the charger directly to a wall outlet, or try a different outlet.
Leave the laptop turned off and charging for 30 minutes, then check whether the battery percentage increases.
If it still doesn't work after that, you need to troubleshoot this with the manufacturer instead because it is not a Windows/Software issue.
