I get the flashing folder with ? when I try to boot up on my MacBook Air 2011. So I boot up holding down "option" key and I get into internet recovery. I choose my network and it starts download, I get a spinning glob with progress bar under it. After it finishes it goes into Mac OS X utility so I went to disk utility and didi a reapir on hard drive, everything checked out okay, so I exited it and went to re install OS X and I go through the terms and start the download but after 15 seconds or so system shuts down. I have booted up using the "D" key to do a apple Hardware Test and everything came back OK on that also. But every time I try the Internet recovery I get the same results, system shuts down right after Lion starts to download. Any suggestions on whats to try next or why system is acting this way?
