@smumar143,

 

Welcome to the HP Forums 🙂 I would like to take a moment and thank you for using this forum, it is a great place to find answers. For you to have the best experience on the HP forum, you could also visit our HP Forums Guide for First Time Here? Learn How to Post and More. I understand your PC boots into a black screen and light on caps lock is blinking. Don't worry I'll be glad to help you.

 

To provide you with an accurate solution, I'll need a few more details: 

Have you recently made any software or hardware changes on the PC before the issue started?

Did this happen after a power surge or power outage? Did this happen after a software or windows update?

Did you perform a Bios update by any chance?

 

In the meantime, let's try these steps here: 

 

Perform a Hard reset on the notebook

Many startup errors and other problems can be resolved by decreasing the amount of power stored in hardware components. Decreasing stored power is sometimes referred to as a "Hard Reset". Use the following steps to perform a hard reset on a computer:

  1. If Windows is open, click Start and then Shutdown.

    If Windows is not open and the computer has power, press and hold the power button on the computer until the computer shuts off.

  2. With the power off, disconnect the power cord from the back of the computer.

  3. With the power off and the power cord disconnected, press the power button on the computer for 5 seconds. The power light indicator on or near the power button might turn on briefly but then go out.

  4. Reconnect the power cord and turn on the power.

For starters please try to roll back the bios from this link: http://support.hp.com/us-en/document/c02693833

Please try both the steps mentioned in the link.

 

If this does not do the trick, please try all the steps from this link: HP Notebook PCs - Computer Does Not Start (Windows 10)

 

Alternatively, you can also go through this support document: If the LEDs blink, or the computer beeps, but it does not start, go to HP Notebook PCs - Troubleshooting LED Blink Codes or Beep Codes During Startup or Boot

 

Could you please respond to this post with the details and with the results of the troubleshooting as this will help me in further assisting you.

Eagerly waiting for your response!

that said, If the information I've provided was helpful, 

give us some reinforcement by clicking the solution and kudos buttons, 

that'll help us and others see that we've got the answers!

Good Luck.
