Hi,

I need help, as I am about to throw my Macbook Air 2011 edition out the window.

I am trying to restore it to the factory default settings, I have formatted the O/S partition and am now going through the Reinstall MAC OS X process, where it downloads a 4GB file from the net to reinstall Lion.

Problem is, this takes ages - like 6/8 hours! Which I don't mind as Ill leave it on over nite, but the flipping thing keeps going to sleep causing the download to fail.

Please, how do I disable sleep mode when I am performing an internet recovery/reinstall ?

Thanks!
