Envy x360 15t-ed100 won’t turn on

[Alan_G24]

My Envy x360 won’t turn on. The power button has always been a bit finicky: I have often had to press it twice for it to turn on. Recently, however, it won’t turn on consistently and I have to try repeatedly over several minutes. Once on, it behaves normally. 
battery health is good. I’ve tried turning while plugged in, while unplugged with a full battery charge, long button press, short press, etc. Doesn’t seem to be predictable. 
Any ideas?

Hardware problem, e.g., bad key, a short in the circuit board?

If you've had issues with the button, you can replace the power button board:

Thanks! Now, I just need to find the part number! 😄
