HP envy 4 won't turn ON, F12 keeps on blinking

[qzyDO]

I was watching something in Netflix when my laptop just went blank and F12(the wifi button) keeps on blinking White. The caps lock key is not lighting up and there is no beep sound too. Just the F12 blinking, and I cant even charge as the charging indicator won't turn on. My battery is non-removable and hence can't reset that way. What can I do ? I saw the led blinking erorecode sheet, my case was not listed. I brought this laptop on 2014.

Try the hard reset/power reset for non-removeable battery:

Immediately after powering on start tapping the Esc key. This will open a menu where F2 System Diagnostics is an option. Tap F2 key and run the tests.

I did it with no avail. Pressing down the power button (and it's different variations) doesn't seem to work. Also when I connect the AC power adapter, the charging indicator in not coming on. (Usully it turns orange). I am pretty sure the Adapter is alright, I will check it with a multimeter now. Still battery power is there as the F12  keeps on blinking..

Have you tried to get into F2 System Diagnostics? Immediately after pressing the power button start tapping the Esc key. This should open a menu where F2 System Diagnostics is an option. Tap F2 key and run the tests.
