I made a little research about your laptop.
If this is your laptop,

then it's less then 1 year old, so I'm not sure that this new laptop has dust problems.
I suggest you to take it to the nearest service point as fast as you can while your warranty valid.
It could be hardware related problem too. They will check for you for free, and even clean it.
