It's cycling through... rebooting over and over. Background: I recently had to buy a Seagate external with the intentions of getting rid of some files so free up space on the MBA before it crashed... power cord/charger just quit working last week. Had to order a new one... plugged in the new one, works fine... green/amber light is on. But I shut it down to do a hard boot... it cycles and never runs a full startup! It just keeps going... Has it crashed??? I sure hope not...
