I used to work with an IT "Expert", a woman who - to listen to her describe her time in computing - all but invented the internet (in the mid 90's as well, email (or any other electronic messaging) wasn't around before 1995! She knows coz she helped invent it!)
She once actually tried to accuse me of deliberately trying to cause her problems because I changed the front of her laptop case and removed the separate "on" button the laptop had always had, leaving only the "off" button so she couldn't turn it on.
Suffice to say, after she'd complained to management who brought me into a disciplinary meeting along with the offending laptop, and the HR person was also obviously in on it when they pointed out that their laptop also had only one power button. Suffice to say her job in IT did not last much longer.
