Most people would hate it if someone messed with their laptop. It's an expensive productivity tool, and someone screwing around with it could cost time, work, or even hundreds of dollars.
But if you've got a rebellious streak (or a grudge), there are ways to escalate your interoffice prank war by changing a few settings on someone else's computer. Just remember, if you can do it to them, they may be able to do it to you, too.
DISCLAIMER: Try these at your own risk. They're fun if your friends and co-workers have a sense of humor, but they can also get you fired for messing with company hardware. Don't be a jerk, and pick your victims very carefully.
