@Sahilm06. Welcome to HP Support Community,

 

Thank you for posting your query; I’m here to help by guiding you through steps to resolve this issue

 

Basic Power Reset

Unplug the charger.

Take out the battery (If removable).

Hold the power button for 30 seconds.

Put the battery back in, plug in the charger, and try to turn it on.

 

Check for Signs of Power

Plug in your charger and look or listen for signs: fan movement, keyboard lights, caps lock LED blinking, etc.

If absolutely nothing happens (no sound, no lights), the motherboard may not be booting at all.

Try a BIOS Recovery

CMOS Reset

I hope this helps.
