@Rut27, Hello and welcome to the HP Support Community!

Thanks for posting your question. I'm here to help you get things back on track.

If your HP laptop powers on but shows a black screen and the Caps Lock key is unresponsive, it could indicate a hardware issue or a BIOS/firmware-related problem. Here are some steps you can try to resolve it:

Perform a Hard Reset

This helps clear any residual power and reset hardware connections.

• Turn off the laptop completely.
• Disconnect the power adapter and remove the battery (if removable).
• Press and hold the Power button for 15 seconds.
• Reconnect the power adapter (without the battery) and try turning it on.

Check for LED Blink Codes

If the Caps Lock or Num Lock LED blinks, it may indicate a specific hardware failure.

• Count the number of blinks and refer to this guide: HP Notebook PCs - Computer beeps or a light blinks during startup | HP® Support

Try an External Display

To check if the issue is with the laptop screen:

• Connect your laptop to an external monitor or TV using HDMI or VGA.
• Power on the laptop and press F4 (or Fn + F4) to switch display modes.

If the external display works, the issue may be with the laptop’s internal screen or display cable.

BIOS Recovery

If the screen remains black, try recovering the BIOS:

• Turn off the laptop.
• Press and hold Windows key + B, then press and hold the Power button for 2–3 seconds.
• Release all keys and wait. You may hear beeps and see the BIOS recovery screen.

If none of the above steps work, it may be a hardware failure, please visit the nearest HP authorized service center, the service team will check and assist you.
