Defective Display Cable
If the external monitor works but the laptop screen remains black, the issue may be with the laptop screen itself.

Proper cooling is essential to prevent overheating and ensure optimal performance. Also ensure that your device's cooling fan is plugged in and working and spinning freely in its housing.
- Remove any accumulated dust or debris from the internal components of your device. It is crucial to maintain proper airflow within your device. Dust or debris can hinder the cooling process, potentially causing issues with the operating system. Regularly cleaning the internals of your device helps prevent excessive heat generation and ensures optimal performance.
- Reset your device's BIOS Settings. To reset your motherboard's BIOS settings, you can try uninstalling and then reinstalling the CMOS battery. By doing so, any stored settings or configurations that may have become corrupted will be cleared, and the system will start with default settings. This helps eliminate potential conflicts or misconfigurations that could be causing the issue you're experiencing.
- Perform a thorough visual inspection of the circuit boards for any signs of burns or damaged components. If you observe any visible damage, such as burns or parts that appear to be physically damaged, the board likely needs to be replaced, especially if it's the board carrying the display cable connector.
