- Thermal Paste: If the CPU or GPU temperatures are consistently high, consider reapplying fresh thermal paste to the heatsink.
- Software Updates: Keep your operating system and drivers updated to ensure optimal performance and stability.
6. Troubleshooting
If you encounter issues after installing the motherboard, consider the following troubleshooting steps:
6.1 Common Issues and Solutions
- Laptop does not power on:
- Double-check all power connections, including the AC adapter and internal power cables to the motherboard.
- Ensure the laptop battery is properly connected or removed for testing with AC power only.
- Verify the power button cable is correctly attached to the motherboard.
- No display on screen:
- Ensure the display cable (LVDS or eDP) is securely connected to both the motherboard and the screen.
- Test with an external monitor if possible to rule out a faulty laptop screen.

- Ensure the hard drive/SSD is properly connected and detected in the BIOS/UEFI.
- Reset the BIOS to default settings.
- System instability or crashes:
- Verify that all drivers are correctly installed and up to date.
- Check for overheating issues; ensure the fan is spinning and heatsink is clean.
- Run memory diagnostic tools to check RAM integrity.
6.2 Compatibility Questions
Q: Is this motherboard compatible with my laptop?
