Ask HN: What's your checklist for when you hand your laptop in for repair?

For instance on Mac I think I should turn on disk encryption, sign out of iCloud, back up on my applications specific configuration files, delete all my local copies of SSH keys, delete all my local copies of proprietary code. I never thought of having a checklist for this before but I think it's useful and there's probably some sort of standard best practice. I'm interested in what are people's responses for different platforms and is there any sort of Open source script that will handle this for you like a "nuke script"... I mean obviously the point is not to Nuke it you want to bring it back later but.... you want to handle if someone somehow has privileged access to everything you want them to have his little surface area of anything valuable as possible.
