• To replace, power off and unplug the system. Locate the battery holder (near the M.2 slot in Figure 3), gently remove the old battery, and insert a new CR2032 V3 battery with the positive side facing up.

7. Troubleshooting

• No Power:
  • Ensure all power cables (24-pin ATX, 4-pin CPU) are securely connected.
  • Verify the power supply is switched on and functioning correctly.
  • Check front panel power switch connection.
• No Display:
  • Ensure monitor cables are correctly connected to the motherboard's integrated graphics ports (VGA, DVI, HD) or a dedicated graphics card.
  • Reseat the RAM modules. Try booting with one RAM stick at a time.
  • Reseat the CPU.
  • Ensure the CPU cooler fan is spinning.
• System Instability/Crashes:
  • Verify all components are properly seated.
  • Check CPU and GPU temperatures.
  • Ensure your power supply is sufficient. A minimum of a 500W brand power supply is recommended for this platform.
  • Update BIOS/UEFI to the latest version (contact customer service for files).
• Peripheral Issues:
  • Try different USB ports.
  • Ensure drivers for devices are installed correctly.

8. User Tips

• Power Supply: This motherboard platform requires a robust power supply. Ensure you use at least a 500W power supply from a reputable brand for optimal stability and performance.
• BIOS/Drivers: If you encounter any compatibility or performance issues, contact customer service to obtain the latest BIOS files and drivers for your motherboard.
• TPM 2.0 Support: A user inquired about TPM 2.0 support. While the B75 chipset itself might not natively support TPM 2.0, some motherboards can have a TPM header for an add-in module. Please check the motherboard for a TPM header or consult JINGSHA support for specific TPM 2.0 compatibility with this model.
