回答“Buzzing, grinding noise coming from rear and centerish?”If you are referring to this problem: https://www.youtube.com/watch?v=J6cBLvCF... then I may have a solution. It fixed mine. I tried hitting that side of the laptop, blowing in the back and all that good stuff. None of it worked permanently. It seemed like the clearance between the actual fan and the base it is attached to was too small. Swaying the laptop back and forth actually changed the scraping sound's pitch. There is a natural wobble of the fan, but swaying should still not make it scrape... that is how I came to the conclusion of the clearance being too low. I decided to pop the back cover off and have a look. Took out the entire fan and opened its casing to where the fan was completely exposed. I used a tiny Flathead screw driver and VERY carefully started prying the fan upward off of its base a bit, until i felt a very slight pop (DO NOT pop the fan of its base). I did this symmetrically all around the fan (this will increase the fan to base clearance). Please do not pry too hard, however. You do...
回答“Trackpad click button is jammed”Ok, this may seem a little weird. My trackpad had the exact same issue and I solved it by blowing in it rather hard. Press your lips on the side that is not "clicking" correctly and blow a few times. Make sure your lips build a good seal though. Or, a short burst of air from a can of can'ed air. May really just be dust/crumbs stuck under there. This should do the trick though.
