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?
I will check out a hardware store in the morning, didn't really know about those, thanks! Though is it a tiny bit possible to get this out in some kind of DIY way too?
