Hey there! @himanisking, Thanks for stopping by HP forums!
I understand when you power on your PC you see a black screen.
Don't worry I'd like to help you out.
Did you make any software or hardware changes on your PC?
Do you see the light on caps lock and num lock light blinking on your PC?
Have you tried checking with a different adapter and wall outlet?
Please try the steps recommended below.
Turn off the computer.
Remove the computer from any port replicator or docking station.
Disconnect all external connected peripheral devices, such as USB storage devices, external displays, and printers.
Unplug the AC adapter from the computer.
Remove the battery from the battery compartment.
Press and hold the Power button for about 15 seconds to drain residual electrical charge from the capacitors that protect the memory.
Insert the battery and plug the AC adapter back into the notebook, but do not connect any of the peripheral devices.
Press the Power button to turn on the computer.
On the Options screen, select Continue and continue to Windows 10.
If a startup menu opens, use the arrow keys to select Start Windows Normally, then press the Enter key.
Reconnect each of the peripheral devices.
After you have completed these steps, run Windows Update and HP Support Assistant to update all device drivers.

I'll watch your reply!
Have a great day ahead! :)
