What to do
- Confirm the charger's wattage meets or exceeds the laptop's original charger rating.
- Inspect the cable and connector for fraying, bends, or a burnt smell.
- Unplug the charger, hold the power button for 15–30 seconds with the laptop off, then reconnect.
- On Windows, check Device Manager for a battery driver issue and try uninstalling and reinstalling it.
- On a Mac, check System Settings battery health for a service warning.
- Try a different, compatible charger if you have access to one.
- If the laptop runs fine plugged in but the battery never rises above its current level, the battery itself is likely the issue.
