@Age_of_myth Welcome to HP Community!

I understand that you are unable to access the boot menu.

Do not worry. I will try to fix the issue.

Please let us know when you connect the adapter to laptop you are getting any lights.

Please try connecting another adapter and check for the issue.

Please perform the hard reset and check for the issue.

Hard Reset:

1) Shutdown the computer.  

2) Unplug all the Adapter and peripherals connected.  

3) Remove the Battery. ( not for Built-in Battery computer ) 

4) Press and hold down the power button for 15 to 20 seconds.  

5) Plug-in the Adapter and put the Battery back into the computer if it's a (removable battery)

6) Try to turn on the computer and check, If the issue persists continue next step
