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?
If you didn’t have a Dremel, try channel lock pliers or vise grips. It’s not going to be in there right and rusted or anything, you just need something to grip it.
