Hi @Pingping1 

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

I understand how concerning this can feel, especially when the laptop powers on but the display remains blank. Since the Caps Lock LED is blinking in a pattern, the notebook is detecting a hardware-level startup issue and the blink code can help identify the affected component.

Please try the following troubleshooting steps:

1. Turn the laptop off completely.
2. Disconnect the charger and any USB devices.
3. Press and hold the Power button for 15 seconds.
4. Connect only the charger and turn the laptop back on.

If the display is still blank:

1. Press and hold the Windows key + B.
2. While holding those keys, press and hold the Power button for 2-3 seconds, then release the Power button but continue holding Windows + B for a few more seconds.
3. If the BIOS recovery screen appears, follow the on-screen instructions.

The blink pattern is important. When you mention "1 to 5 blinks, then 3 fast blinks," please confirm:

• The exact HP Pavilion model number.
• Whether the Caps Lock blinks 5 times followed by 3 quick blinks, or another sequence.
• Whether the fan spins and you can hear any sounds from the laptop.

With the exact blink sequence, we can help identify the next troubleshooting step more precisely.

Take care, and have an amazing day!
