My MacBook Pro hasn't been charging. It's a Mid-2010 model. When plugged in, the LED is simply blank. I've tried a different charger, and it's still blank. I'm guessing it's the MacBook... Edit: That's really weird... both MacBook Pros, with two seperate chargers, won't charge with two sockets (that work... the router is working, etc), while it works in the living room. A mystery I'll solve later. Sorry for the trouble.
