Thanks for taking an interest in the HP Support Forums! After reading your post I see that your HP spectre x360 notebook is not powering on. I would like to help you out with this issue today.
Examine the adapter and power cord for physical damage
Test the power from the AC wall outlet to the notebook connector.
Start computer using the battery only
Check that the lid switch moves freely
When you have completed the troubleshooting steps, there should be power available to the computer. When you press the power button, the LEDs should glow, and you should hear the sounds of the fan and the hard drive spinning.
If the battery does not accept the charge or the notebook does not turn on without the AC adapter, contact HP to order a replacement battery.
Let me know how it goes.
I hope it helps and if you feel I have answered your question and concerns,
Please mark this post as a solution accepted and Kudos would also be appreciated.
