HP Envy x360 I5 now powering on

[behunk]

My HP ENVY x360 I5 laptop just died. I tried all the recommended solutions (uinplug and hold power for 20 secs and replug, also hit Windows + B + Power button for 3 to 4 secs + release Power Button and hold Windows + B for additional 3 to 4 secs)

"Windows + B + Power button for 3 to 4 secs"

That is incorrect.  This bit takes patience.

Make sure you have the power adapter plugged in.

It can take up to a minute for the PC to respond and how a recovering BIOS message on screen.

Is there a lit power LED when the power adapter is plugged in?

Thanks for your response Erico.

I retried again and waited the full minute as you suggested. I still get no results. 

There is no lit LED when the power adapter is plugged in. No fan running. Absolutely no power or boot up when plugged in nor when unplugged. It was literally all working an hour ago

You're welcome.

No lit power/charge LED means there is either a problem with the power adapter or the system board has damaged components.

Another possibility is that the header where the power adapter plugs into the laptop has a damaged pin.

Use a flashlight and take a close look.

I would try a known working compatible power adapter if I were you. 

If it still does nothing, now you know that your system board has damaged components.

Looks like a dead mother board. Thanks for all your help
