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?
Do you have a large Philips bit (like #3 or #4, the largest one that will fit in whats left of the screw)? You could try using that and tapping the end with a hammer (not too hard since its plastic) while gently twisting it. This usually shocks the screw and breaks it loose.
