7. Solució De Problemes
If you encounter issues with your power adapter, refer to the following troubleshooting guide:
| Problema | Causa possible | Solució |
|---|---|---|
| El dispositiu no s'encén | Sense energia des de la presa Connexió fluixa Vol incorrectetage/actual Incorrect DC connector size/polarity Faulty adapter/device | Prova la presa de corrent amb un altre dispositiu. Assegureu-vos que totes les connexions siguin segures. Verify device's power requirements match adapter's output. Confirm DC connector size and polarity. Try a different compatible adapter or test the device with its original adapter if available. |
| L'adaptador s'escalfa | Funcionament normal (lleugera escalfor) Sobrecàrrega Poca ventilació | Una lleugera escalfor és normal. Si s'escalfa excessivament, desconnecteu-lo immediatament. Ensure device's current draw does not exceed 3A. Place adapter in a well-ventilated area. |
| Potència intermitent | Connexió fluixa Damaged cable/adapter | Comproveu i assegureu totes les connexions. Inspect cable and adapter for damage. Replace if damaged. |
