Why is there no sound from the audio system after the Boyue runs out of battery?
3 Answers
After the Boyue runs out of battery, there may be no sound from the audio system due to connection and setting issues, loose power cable connections to the audio system, uninstalled sound card drivers, or the audio volume being switched to mute. Solutions for the audio system not working: If there are connection and setting issues, first unplug the audio cable from the main unit and try listening with headphones. If there is sound, check if the settings are adjusted correctly. If the power cable connection to the audio system is loose, it may be because the cable is not properly inserted. Simply reconnect the power cable to the audio system. Solutions for the car running out of battery: Check if there are any long-term standby car appliances in the vehicle. If so, the wiring method needs to be changed. If it is not due to car appliances, it is recommended to drive to a local branded battery specialty store to connect to a computer for battery performance testing. If it is a battery level issue, charging will suffice. If it is a performance issue, the battery needs to be replaced.
A few days ago, I also encountered the issue of the audio system not working after my Boruiyue's battery drained, which was quite annoying. I believe the root cause is that the battery voltage was too low, and the audio system automatically cut off power to protect itself from damage. It's important to know that electronic devices like audio systems rely on stable voltage. Once the battery is drained, voltage fluctuations can trigger the amplifier module's protection mechanism, preventing sound output. Additionally, after a battery drain, the vehicle might enter an energy-saving mode, temporarily disabling the audio system until charging returns to normal. I also noticed that the system might perform a soft reset, requiring you to re-pair Bluetooth or check settings. The safest solution is to fully charge the battery first. If the issue persists, try manually rebooting the audio system or checking the relevant fuses in the fuse box. For daily use, it's best to develop a habit of regularly checking the battery and avoid frequent short trips that drain power.
Last month, my Boyue experienced a battery drain incident, and the audio system completely went silent. I suspect it was due to the system's safety design, where the audio is prioritized to shut down under low voltage to prevent damage to sensitive circuits. During actual troubleshooting, I found not only was there no sound from the audio system, but the dashboard also flashed warning signals, indicating insufficient voltage was affecting the vehicle's entire electronic architecture. Experience tells me that after a battery drain, don't rush to the dealership; first, try fully charging the battery with a charger. In most cases, the audio system will automatically recover. If that doesn't work, check the rear fuse box for any blown fuses, usually the one labeled F20 or F30. Additionally, Bluetooth connections may sometimes lose signal and require re-pairing with the phone. A preventive suggestion is to drive more frequently on long trips to maintain battery activity.
