It certainly looks like a hardware issue with the unit and it may need to be serviced.

Hi thanks for replying!

So my model is the HP ENVY NOTEBOOK 15t-ae100
Serial # cnd5493nr3
Product # L8y93av

And no my warranty ran out about 2 weeks ago. I do not think there was a recent bios update. Before this all was happening i was having some HDMI problems where my laptop would not detect any sort of external monitor via HDMI port. So i did a rollback
And when i was restarting i did some bios test and thats when thr computer blanked out and shutdown. Now it wont turn in properly. As of this morning now only thr power button LED turns on but only for a second then turns off. And the computer stays off
