So I got a prompt to update my Win 10 version, I left it to update overnight, I must have not plugged it in and the battery was low during the time of the updates, So I woke up to a dead laptop, plugged it in and now it does not display anything but the fans run at full RPM.

HP Notebook - 15-af114au

(Please un-mute the audio to listen to the fans)

I also tried replacing the RAM but it still does not work.

Thanks
 
Solution
Try a motherboard reset, remove the main and CMOS battery, hold in the power button for about 30 seconds. Plug in the batteries again, plug in the wall power, leave it for about 30 mins, see if it turns on after that. It may take a few attempts to power on. If that does not work, then motherboard may be bad.

I guess the motherboard works since it beeps when I remove the RAM.

Yes the error beeps with no RAM shows the motherboard has life, but from my experience the fans running at full speed is a motherboard failure. Did you try that reset with removing the batteries and hold in the power button (it's called "flea power")?
Yup, It doesn't work unfortunately.
