You can't do your school work.
I tried the magnetic connector both ways (it is omnidirectional), five different outlets, and both the wall wart and 3 prong attachments and no juice is getting to the Mac.
Today, I'm on Ed's machine and banging out schoolwork that doesn't require me to download stuff. This means the crazy easy classwork that's not due until February 14th is done and turned in, the stuff that I need to turn in next Monday has to wait and then as soon as I'm done reading as many tutorials as I can on this machine, I'll be sitting with my lone textbook and reading for Tuesday night's class.
I admit it, I'm a Machead now. I keep hitting F3 to toggle screens and do ctrl x ctrl c ctrl v instead of dropping the first part.
A drive over to Brandon in the morning to the Genius Bar is on tap. I fully expect to walk out ten minutes later with a new cord.
