Hi @Kay379,

Welcome to the HP Support Community.
 

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

Thank you for reaching out. If your HP laptop powers on but the screen remains black, please try the following steps:
 

1. Perform a Hard Reset

• Turn off the laptop.
• Disconnect the AC adapter.
• Disconnect all external devices (USB drives, printers, docks, etc.).
• Press and hold the Power button for 15 seconds.
• Reconnect the AC adapter and turn the laptop on.
   

2. Increase the Screen Brightness

• Press the brightness increase key on the keyboard several times to make sure the display is not dimmed all the way down.
   

3. Test with an External Monitor

• Connect the laptop to an external monitor or TV.
• Turn on the laptop.
• Press Windows + P several times to cycle through the display modes.
• Check whether an image appears on the external display.
   

4. Check for LED Blink Codes

When you press the Power button:

• Does the Caps Lock or Num Lock key light blink?
• If so, count the number of blinks and let us know the pattern.
   

5. Run HP Hardware Diagnostics

• Turn the laptop off.
• Turn it on and immediately tap F2 repeatedly.
• If HP PC Hardware Diagnostics opens, run the Memory Test and System Tests.
   

6. Try HP BIOS Recovery

• Turn the laptop off.
• Press and hold Windows + B.
• While holding those keys, press and hold the Power button for 2–3 seconds.
• Release the Power button but continue holding Windows + B until the BIOS Recovery screen appears.
• Follow the on-screen instructions if the recovery starts.

I hope this helps.

Take care and have an amazing day!
