## 故障排除

### 风扇在系统关机后仍然开启

有用户报告 Penta SATA HAT 的风扇在系统关机后仍然保持开启状态。这可能是由于以下原因：

1. **电源管理问题**：某些电源配置可能导致风扇在关机后继续供电
2. **软件配置问题**：`rockpi-penta` 服务可能未正确停止
3. **硬件设计**：风扇可能由独立的电源电路供电

**解决方案**：

1. **检查电源连接**：确保系统完全断电，而不是进入待机状态
2. **停止服务**：在关机前手动停止 `rockpi-penta` 服务：
```bash
sudo systemctl stop rockpi-penta.service
```
3. **修改配置**：如果不需要风扇功能，可以禁用风扇或降低温度阈值：
```ini
[fan]
lv0 = 60 # 提高温度阈值，使风扇更少启动
lv1 = 65
lv2 = 70
lv3 = 75
```
4. **物理断开**：如果问题持续存在，可以考虑物理断开风扇连接

**注意**：风扇在关机后短暂运行可能是正常现象，特别是在高温环境下。如果风扇持续运行，建议检查系统是否完全关机。

## Troubleshooting

### Fan remains on after system shutdown

Some users have reported that the Penta SATA HAT fan remains on even after system shutdown. This could be due to:

1. **Power management issues**: Certain power configurations may keep the fan powered after shutdown
2. **Software configuration problems**: The `rockpi-penta` service may not be stopping properly
3. **Hardware design**: The fan may be powered by an independent power circuit

**Solutions**:

1. **Check power connection**: Ensure the system is fully powered off, not just in standby mode
2. **Stop service**: Manually stop the `rockpi‑penta` service before shutdown:
```bash
sudo systemctl stop rockpi‑penta.service
```
3. **Adjust configuration**: If fan functionality isn’t needed, disable the fan or raise its temperature thresholds:
```ini
[fan]
lv0 = 60 # Raise thresholds so the fan runs less often
lv1 = 65
lv2 = 70
lv3 = 75
```
4. **Disconnect physically**: If the problem persists, consider physically disconnecting the fan

**Note**: A brief fan run after shutdown may be normal, especially in hot environments. If the fan continues to run, check whether the system is completely powered down.
