Hi @V-_1,

Welcome to HP Support Community.  

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

If your HP laptop's screen is partially black and occasionally displays lines of different colors, it may indicate a hardware issue with the display. Here are a few troubleshooting steps you can try to diagnose and potentially resolve the problem.

• Check for loose connections: Ensure that the video cable connecting the display panel to the motherboard is securely plugged in. If it's loose, reseat the cable and see if the issue persists.
• Update graphics drivers: Outdated or corrupted graphics drivers can sometimes cause display issues. Visit the HP support website and download the latest graphics drivers for your laptop model. Install them and restart your laptop to see if it resolves the problem.
• Test with an external monitor: Connect your laptop to an external monitor using an HDMI or VGA cable. If the external monitor displays correctly without any black areas or lines, it suggests that the issue is specific to your laptop's built-in display.
• Run built-in hardware diagnostics: Many HP laptops have built-in hardware diagnostic tools that can help identify potential issues. Restart your laptop and repeatedly press the appropriate key (often F2 or F10) during startup to access the diagnostic utility. Run a comprehensive test, including the display test, to see if any errors are detected.

I hope this helps. 
 

Take care and have a good day.
