    I updated my 13" MBA with the 10.10.4 update. When prompted I clicked restart and have had a black screen ever since. Any ideas? Thank you!

    How long did you keep pressing the power button? Occasionally my MBA takes over one minute to power on.

    No joy. No sounds or lights or anything. Guess I will be making a trip to the Apple store.
