@Corest, Welcome to the HP Support Community! 

Thanks for reaching out about your query regarding black screen!  
We're thrilled to have the opportunity to assist you and provide a solution.

It sounds like your HP Pavilion 16 is displaying a BIOS beep code, indicating a hardware issue. The blinking pattern of 5 slow and 3 fast blinks typically points to a specific issue, and it seems like a failure related to the system's motherboard, or possibly an issue with the RAM or graphics.

Here's what you can try to troubleshoot the issue:

Power Cycle:

• Power off the laptop completely by holding the power button for 10-15 seconds.
• Unplug the charger, remove the battery if possible (for models with removable batteries), and press and hold the power button for 15 seconds again to discharge any residual power.
• Reconnect the battery and charger, then try powering it on.

Check RAM:

• If you're comfortable opening the laptop, remove and re-seat the RAM modules to ensure they’re properly connected.
• If the laptop has more than one RAM module, try booting with only one module at a time to see if one might be faulty.

External Display:

• Try connecting your laptop to an external monitor or TV to see if there’s any display output. If the external monitor shows the screen, the issue might be with the internal display or graphics card.

BIOS Reset:

• Some HP laptops allow you to reset the BIOS by pressing a key combination when powering on. You can try pressing Esc or F2 as soon as you turn the laptop on to access the BIOS or recovery options.

Let me know if you need further assistance!

Take care, and have an amazing day!
