Hi @MUNS777 

Welcome to the HP Support Community! We're here to help you get back up and running.

I understand that the laptop is not displaying anything on the screen, and the power LED is blinking in a repeating pattern. Thank you for clearly describing the LED behavior, as that can help narrow down the cause.

To provide the appropriate troubleshooting steps, could you please confirm:

1. The exact HP laptop model (or product number).
2. Does the Caps Lock LED or Num Lock LED blink as well? If yes, how many times does it blink before pausing?
3. When you press the power button, can you hear the fan spinning or any other sounds from the laptop?
4. Have there been any recent events before this started, such as a BIOS update, Windows update, battery replacement, drop, or liquid exposure?
5. Have you already tried a hard reset or connecting an external monitor?

Once these details are available, I can guide you with the most relevant HP troubleshooting steps.

We're looking forward to helping you get back up and running! 

Regards,
