MacBook Pro :: Bluetooth Not Available - No Information Found

I recently bought the new base model 13-inch MacBook Pro, which was running perfectly until yesterday. Yesterday, the machine ran out of battery power and went into safe sleep. When I plugged in the power cord and woke it up, the bluetooth symbol in the menu bar had a jagged line through it. On restart, the bluetooth symbol had simply disappeared, and system profiler is showing bluetooth as "No information found.". I have had this problem before with a 2006 macbook, but it was solved by a restart. On searching the web I have found a number of suggested solutions, each of which I have tried: resetting PRAM, resetting SMC, deleting various bluetooth preferences, reinstalling OS X. None of these suggested solutions have worked.
