I can't turn on my Mac Book Air after upgrade the Lion software. Please, can you help me?
I bought a Mac Book Air 3 month ago. I upgrade Lion software several hours ago. Later I reboot and I left to work. When I arrive, I can't turn on my MAC. Only light up the capital letter light, all the other parts are
dead o seem to be. Can you tell me what I have to do to solve the problem, please?
