I know this laptop cost you lots of money, but "out there" laptops are toasters.
Even if your so called pros will do it I don't think they would do a good job. They gonna wipe it and run the vacuum on it and that's it.
Me, I disassemble the keyboard, get in there with a box of q-tips, am looking at a 2 hours job minimum, but that's me.
If cleaning the innards, vacuum, replace paste/fan what pros do will suffice if you don't feel like getting inside.
