Well just a little bit of update for my case.
The technician yesterday replaced the DVDROM and touchpad, things works fine now except for the SSD still.

So he decided to escalate it and the SSD will be replaced, supposedly today. Guess what? They got my address wrong lol. I live in Kuala Lumpur, but somehow in the repair order my address is somewhere in Kuantan.

Good job Dell.

Dell warranty is regardless where your purchase from, even you vacation in Sabah or Sarawak, Dell technician will go there to fix it. Even that every month you travel in different state.
P/S: Where you are, where dell be.
