I have an almost new Macbook Air. I started to use Time Machine for the first time with a brand new "My Passport" hard drive. I had to unplug it during the process and it was left unplugged for quite some time. Then it went to sleep probably or maybe not, but I plugged it. Then unplugged again (one charger was shared between two Macs).

Cannot turn it on now! The light on the plug cord is green as it is fully charged. I changed the socket just in case. I tried with USB My Passport drive plugged in and not. Nothing happens.

    Take it to the shop. It is still covered by the warranty unless you did something silly to void it. – M_dk Oct 21 '13 at 2:39

Keep pressing your power on button for 5 seconds.
The press it again for normal power-up.

  • Thanks, worked. Though, I tried that before, just did not press and hold long enough. So, first Time Machine backup should go without interruption. I had an option checked when backup gets interrupted on power supply disconnected. Corrupted backup recovery is a long process. – mel Oct 21 '13 at 16:43
