Thanks for using the Lenovo forums.
You can simply take it apart and blow out any dust using the hardware manual on the support page.
I personally recommend using a can of compressed air duster, something like this.
Hope this helps, let us know how you get on.

You just need to take out all the back panel screws, wiggle the back panel (It may not be easy the first time but still dont force it too much/bend).
Once you take it out, use a compressed air can to blow the dust out. Real easy.
Here is your HMM -

Sure won't. The screws have a tiny amount of loctite to help keep them tight in transit, but removing the back cover is not a warranty issue. In fact, many parts of Lenovo machines are Customer Replaceable Units, or CRUs. You can remove the back cover to upgrade your hard drive and RAM with no concern.
As mentioned, you remove the screws around the outside of the machine on the bottom. Most are short screws, but there are a couple of longer ones by the screen hinge. Once the screws are removed, I get my fingers underneath the front of the laptop and slowly open it, hinging towards the rear. You'll feel the clips come undone. The bottom piece extends a bit underneath the screen, so as you get to the back, you may need to open up the screen a bit to fully pop it off.
Once removed, you can clean both the filter and the actual heatsinks in the laptop. If the dust is not coming off the filter, you can run it under some warm water to loosen it up. Just be sure to dry it before re-installing.
