How to Fix: Can't view laptop bios on external display even after disconnecting the bui

Troubleshooting laptop bios display issues on external monitor

The issue is likely due to the laptop's built-in screen being connected to the motherboard, which prevents the external display from receiving video signals. To resolve this, you need to disconnect the built-in screen from the motherboard.

🛠️ Step-by-Step Verified Fix:

  1. Disconnect the built-in screen from the motherboard.
  2. Connect the external display to a free port on the laptop's graphics card.
  3. Reboot the laptop and enter the BIOS settings by pressing the key indicated in your laptop's manual (usually F2, F12, or Del).
  4. In the BIOS settings, set the external display as the primary display and save changes.
