I decided on cleaning my laptop fans today, which I’ve been procrastinating for about a year now because of this one screw. But I just can’t seem to open this with my screwdriver, since whatever I did back when I last opened it it’s nearly circular now. Is there a way to unscrew this?
Carefully dremel a slot in the screw head and use a flat head screwdriver.
Make sure you don’t get any dust into the electronics.
