Hi there,
Based on the information provided, it seems like your Blackshark 04 has completely shut down and is not responding to any attempts to power it on or charge it. There could be several possible reasons for this issue, including a faulty battery, a damaged charging port, or even a software-related issue.
Here are some troubleshooting steps that you can try to determine the cause of the problem:
1. Check the Charging Cable and Adapter: Sometimes, the issue may be with the charging cable or adapter. Try using a different cable and adapter to see if that works.
2. Check the Battery: If the battery is faulty, it may not hold a charge or power on the device. You can try replacing the battery to see if that resolves the issue.
3. Check the Charging Port: The charging port may be damaged, preventing the device from charging properly. Try cleaning the charging port with a soft brush to remove any dirt or debris that may be blocking it.
4. Try a Hard Reset: Sometimes, a hard reset can resolve software-related issues. To do this, press and hold the power button and volume down button simultaneously for about 10 seconds or until the device restarts.
If none of these troubleshooting steps work, the issue may be more serious and require professional repair. You can contact the manufacturer or a certified repair technician for further assistance.
I hope this helps! Let me know if you have any other questions.
