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?
Put a rubber band between screwdriver and screw, otherwise the other things already stated like CA glue, filing a flathead groove, or drilling the cap off
in the future use the appropriate sized driver and retire drivers when they become stripped
This. The rubber band trick works well for the first step. I came to say this.
The rubber band trick is great, and very low effort/cost. I want to say, though, that it can take substantially more force than it looks like it should on small screws like this. You also don’t have to use something shaped for the original driver of the screw. With the rubber to help it, a round cylinder a little smaller than the head of the screw can work very well.
Just so you know, OP, CA glue is a generic term for CyanoAcrylate glue, like Super Glue or Krazy Glue.
Bring out the KraGle!
