Keyboard and trackpad not working, but the power button is working.
I have recently bought my first ever ifixit tool kit and I was finally able to open up my macbook. I've been wanting to do this for a while because the back cover seemed a little bent so I wanted to see what was going on.
So I removed the back cover using an iFixit guide. When I had it removed I just looked at all the components (I mainly wanted to see if the bend in the back cover might have come from a battery issue) but I couldn't find anything.
I removed a bit of dust from the now loose back cover - not from any of the components.
Then I put it all back together, started the MacBook back up and discovered that my keyboard and trackpad had stopped working! The power button still works fine though.
I have no idea what I might've done wrong so if anybody on here could maybe help me out I'd be very happy :)
