The most likely causes are:

1. The 20V charger has malfunctioned or gone into a protective shutdown mode.
2. There is an issue with the Chromebook's charging port or circuitry, causing it to only charge with a lower voltage phone charger. Performing a hard reset by pressing Refresh + Power may resolve this.
3. The Chromebook's battery may be faulty or degraded, preventing it from accepting a full charge from the 20V charger. Checking the battery health through the diagnostics menu can confirm this.

If the above troubleshooting steps do not resolve the issue, you may need to replace the 20V charger or potentially the Chromebook's battery or charging port.
