There is always a lot of dust, and because I have a laptop I always make sure its dust free, but there will always have dust going inside your laptop as well. I was wondering is this actually harmful for the laptop, as dust accumulates inside the laptop.
Whether it is harmful or isn't, should we actually still open up our laptop and clean it from the inside. I've never actually done this myself, thinking that a laptop should not be opened unless really needed to (e.g. for changing a laptop part). If it is something we should do, can we do it ourselves or should it be taken to a shop.
