Hi @Rae3111, Welcome to HP Support Community. 

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

That sounds like a catch-22! 
Let's try these steps:

Perform a Hard Reset

1. Disconnect the charger and remove any external peripherals (USB drives, external monitors, etc.).
2. If the battery is removable, take it out.
3. Press and hold the power button for 30 seconds to drain residual power.
4. Reinsert the battery (if applicable) and connect the charger.
5. Press the power button again and see if it turns on.

Check the Power Adapter & Charging Port

1. Ensure the charger is properly connected and check if the charging LED light is on.
2. Try using a different power outlet or charger if available.
3. Inspect the charging port for dust or damage.

Perform a BIOS Reset (Win + B Method)

1. Power off the laptop completely.
2. Press and hold the Win + B keys, then press the power button for about 3-5 seconds.
3. Release all keys and wait to see if the screen lights up.

Test With an External Display

• If you hear fans spinning but no display, connect an external monitor via HDMI or DisplayPort and check if you get an output.

Identify Any Blink Codes or Beeping Sounds

• If the power button blinks in a sequence or there are beeping sounds, they indicate specific hardware failures. 

I hope this helps. 

Take care and have a good day.
