Welcome to HP Forums,  

This is a great place to get support, find answers and tips,
Thank you for posting your query, I'll be more than glad to help you out 🙂

I see that HP Envy notebook is not booting up,
Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details:

• When was the last time it worked fine?
• Have you tried any troubleshooting steps? 
• Have you made any hardware/software changes?
• What happens when the computer is powered on?

While you respond to that, I recommend you to perform the following steps to isolate the issue and arrive at a fix:

Let's perform a hard reset: Remove all externally connected devices, 

1) Shutdown the computer.  

2) Unplug all the Adapter and peripherals connected.  

3) Remove the Battery.  

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.  

6) Try to turn on the computer. 

Hope this helps! Keep me posted for further assistance.
