The AC adapter for my PowerBook died this morning. It was weird–it was working fine at home this morning, but it completely failed to work at the office. I changed power plugs and wiggled all of the connectors, all without success.

Fortunately, my office is only 20 minutes from one of the local Apple stores, so I was able to dash out and get a replacement. After 40 months, I guess I’m not really surprised when pieces die on my laptop anymore.
