Hi @billhvac1967,

Welcome to The HP Support Community.  

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

I understand the issue you're describing with your HP Pavilion 17-f071nr Notebook PC, where the power button comes on, the caps lock button flashes, and there's a black screen with a beeping noise, indicates a hardware-related issue, often related to memory (RAM) or display problems. The flashing Caps Lock key and beeps usually correspond to a specific error code that can help identify the problem.
 

Troubleshooting Steps:

1. Check the Beep Code

• The number of beeps and the flashing pattern of the Caps Lock key represent a specific hardware error. Count the number of beeps or flashes (e.g., 2 beeps, 3 beeps, etc.) and refer to HP’s beep code guide to identify the issue.

2. Hard Reset the Notebook

• Turn off the notebook.
• Disconnect the power adapter.
• Remove the battery (if possible).
• Hold down the power button for 15 seconds to discharge any residual power.
• Reconnect the power adapter without the battery and try turning on the notebook.

3. Reseat the RAM

• Power off the laptop and unplug the AC adapter.
• Open the back cover of the laptop to access the RAM.
• Carefully remove the RAM sticks and reinsert them to ensure they are seated properly.
• If you have two RAM sticks, try booting with one stick at a time to identify if one might be faulty.

4. Check the Display

• Connect an external monitor to your laptop using an HDMI or VGA cable. If the external monitor shows a display, it indicates the issue might be with your laptop’s screen or display cable.

5. Battery and Power Issues

• Try booting the laptop with the battery removed, using only the AC adapter. If this resolves the issue, the battery may be faulty.

6. BIOS Reset

• Power off the notebook.
• Hold down the "Windows" + "B" keys simultaneously, then press and hold the power button for 3 seconds. Release the power button but continue to hold the "Windows" + "B" keys until the BIOS recovery screen appears. If this works, follow the prompts to reset the BIOS.
