ABSOLUTELY FRUSTRATED!! I have had my Macbook Air i7 for 2 weeks, it's died, had a new logic board, it's not gone to sleep. So I reset the P-Ram, that basically broke it again. Resetting SMC saved it. Crashes 4-6 times a day, it's not Chrome. It's cursed.

Thanks for looking in to this... much appreicated.

OSX is up to date with the latest EFI SMC firmware update. Mountain Lion totally up to date.

Yes I migrated my old Air to this new Air.

I have seen kernal panics before. This was a panic was during startup, the grey screen got a whole bunch of black lines on it filled with code, very Windows like, and it's as if I was seeing behind the scenes as it loaded and did a CPU panic.

As I type this, I restarted in to bootcamp Windows 7 last night. Fresh install of that. It was restarted this morning to Mac due to updates. So I restarted to Windows, and on the desktop it just froze. Then I had to hard restart it. I did disk and permissions repair on the Mac side. Started back in to Windows, it's frozen on startup. Had to hard restart. The machine will now not power on at all. It is unresponsive with power button holding down. Holding the power button down with shift. Nothing. Resetting SMC now. Nothing. Pull power out and it springs back to life. I restart Mac to boot in Windows again. Screen just goes black and it will not power on. Reset SMC to get it going. This is just after restarting the machine. Opening Windows now, startup is being repaired as it's crashed during start-up. Looks like it's hung again, but I am just going to leave it.

That's been the last half hour with the machine. And I am supposed to be able to work on it?

I have had a time machine drive plugged in, and an iPod, both have been removed and still no joy. Problems.

As I said earlier the panic was during startup.

It's just cursed. To have had a new logic board already? Something is faulty, power maybe? I just don't know at this stage.

I might have to, I have done this on the Windows side and it too is having problems. Two OSs having the same problems = hardware in my book.

It's just going from bad to worse, it's not starting up at all, for like 10 minutes nothing. Then the power adaptor light goes red, I reset the SMC and finally after all that time it comes back alive. This is after another CPU panic during start up. It's now stuck on a grey page that states ' my computer restarted because of a problem. Press a key or wait a few seconds' well it's been a few minutes and it's doing nothing.

It looks like it is officially bricked again. Sigh. Not fun.

Might be time for logic board number two. New machine please.

This is like 'live scoring' haha, but it's back alive and I am doing a time machine restore to see if that helps.

Interesting, since doing a restore, now the machine is back alive. It's frozen crashed once already. Typical.

But...

The battery has an X through it, it says it's powered by the power adaptor. But it's not even plugged in!

A restart fixed that.

I answered the four questions ages ago, did you not see that?

I also was replying to myself later, with a live update of the woes.

Thanks that's where I am with it, am going to do that when I have time, cheers man.

The method I used to migrate was firstly, Air to Air via ethernet, then time Machine backup as I had wiped my other machine to get it ready for sale.
