Internal display is not working and I am using external display only on clone display mode

[Gawihawk]

I had problem with the power jack and had to replace it. After replacement I could not read anything on display. I connect to the large screen on clone mode to operate the laptop. I don't know what to do next

Hi @Gawihawk,

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

If your internal display is not working and you're currently relying on an external display in clone mode, here are several steps you can take to diagnose and potentially resolve the issue.

Check Display Settings:

• Ensure that your laptop's display settings are correctly configured. Right-click on the desktop and select "Display settings" (or go to Settings > System > Display).
• In the display settings, ensure that the internal display is recognized. If it is not, try to detect it by clicking on the "Detect" button.

Check Hardware Connections:

• Since the problem started after replacing the power jack, it's possible that the internal display connector might have been disturbed. Carefully open the laptop (if you feel comfortable doing so) and check the connections to the internal display. Ensure that all cables are properly seated and secured.

Update or Rollback Graphics Drivers:

• Sometimes, updating or rolling back your graphics drivers can resolve display issues. Go to Device Manager, find your display adapter, and update the driver. Alternatively, if the issue started after a recent update, try rolling back the driver.

BIOS/UEFI Settings:

• Check the BIOS/UEFI settings to ensure that the internal display is enabled. Restart your laptop and enter the BIOS/UEFI setup (usually by pressing F2, F10, DEL, or ESC during startup). Look for display settings and ensure the internal display is not disabled.

Hardware Diagnostics:

• Run hardware diagnostics to check for any hardware issues with the display. HP laptops often have built-in diagnostics that you can access by pressing a specific key combination during startup (usually ESC or F2). Run the display test to check for any errors.

Test with a Different OS or Bootable Media:

• To rule out software issues, you can boot from a live USB drive with a different operating system (e.g., a Linux distribution) to see if the internal display works. If it does, the issue might be related to your current operating system or drivers.

By following these steps, you can systematically diagnose whether the issue is software or hardware-related and take appropriate action to fix the internal display on your HP laptop.

I hope this helps.

Take care and have a good day.
