After donning or doffing my jacket at work, I try to remember to touch the metal edge of the cube dividers to discharge any static electricity from my skin, but sometimes I forget.

Twice or thrice, it has happened that upon touching my metal keyboard, static electricity has sparked strongly enough to make the monitor go blank for a moment. I worry about my laptop getting damaged. The static electricity must be traveling along the keyboard cord to the laptop dock. I wonder if the keyboard cord has a ground wire that is purposely connected to the keyboard case.
