laptop model : HP ENVY - 13-ah0044tx
mx150 gfx
i7 8th gen
with ssd

removed fan and tested laptop and same sound
change laptop with 2 motherboards and same sound
reset bios to factory default same sound
changed ssd and checked same sound
RAM is sodered.
cant figure out why click click sound is coming only when laptop is tilt at an angle only and not otherwise laying flat on table
also sound is like continuous clicking of mouse button can be heard from righ side , under laptop when cpu is running at about 30 percent and above and only when tilt horizontal at and angle.

Any Ideas to fix

Does your laptop have a DVD Drive ?? Maybe that can be the problem. Clicking sound should only come from mechanical things (obviously) , but it could also be coil whine which is unfixable. I don't buy HP laptops because of issues like these, it's better to spend 50 bucks more to get higher quality product like ASUS , Dell , MSI or Lenovo.
