In a few days I will replace my defective optical drive with a super drive from OWC. This will be my first time working on the Mac. I want to make sure I don't make that little static mistake to ruin the Mac. Exactly how do I discharge the static? With power cord removed I plan to work on a wooden table and linoleum floor. Is that enough? Should I remove the battery as well? I appreciate all tips to avoid a stupid and costly error.
