(Computer) Gremlins II: The New Batch

I got my PowerBook back on Friday. It worked all day Friday. It worked all day Saturday. It worked all day Sunday.

On Monday (say it together, everybody!), it stopped working!

It just won’t turn on. I went through the whole rigamarole (resetting, zapping PRAM, all sorts of junk), but it’s getting shipped back off to Texas tomorrow. Again.

What did I do to earn so much bad computer karma?
