Hi @Phantomx230,

Welcome to HP Support Community.

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

It sounds like your laptop's screen might have been damaged by the tap. The rainbow screen glitch could indicate a variety of issues, ranging from a loose connection to actual damage to the display. Here are some steps you can try to troubleshoot the issue.

• Restart the Laptop: Sometimes, a simple restart can resolve software-related glitches.
• Check External Connections: Ensure that all cables (if any) connecting your laptop to an external monitor or other devices are secure. If you're using an external monitor and it's displaying fine, the issue might be with your laptop's screen specifically.
• Update Graphics Drivers: Outdated or corrupted graphics drivers can cause display issues. Go to the HP website and download the latest drivers for your graphics card.
• Check for Physical Damage: If you're comfortable doing so, carefully inspect the laptop's screen for any visible signs of damage, such as cracks or dents.
• Connect to an External Monitor: If possible, connect your laptop to an external monitor to see if the issue persists. If the external monitor displays normally, the problem likely lies with your laptop's screen.
• Run Diagnostics: Many laptops come with built-in diagnostic tools that can help identify hardware issues. Check your laptop's user manual or HP website for instructions on how to run diagnostics.

I hope this helps.

Take care and have a good day.
