I have just moved over to a Macbook Pro from my old Macbook. Thanks to the Migration Assistant, it was an easy task, but I am now having an annoying issue: I have both computers on with all the same settings and everything identical. The wifi settings, the Energy Saving settings - everything.
Now, when the computer goes to 'Sleep', the behavior is different is between the two computers. I have Skype on. If I'm away for about an 1 hour, Skype will go offline. As a result if someone were to Skype me, the old Macbook will react - my Skype will ring when they call me and obviously they see me as online (despite the screen being off and the computer in sleep mode).
However, my new Macbook Pro will not ring. The party that wants to reach me will think I'm offline because the network connection gets disabled somehow. On my old Macbook, I just need to touch the trackpad and the screen comes on, but on my new Macbook pro I need to press a key (some websites state that this is the new thing on new version such as Lion and Mountain Lion), and the computer will quickly come on, pick up the wifi and only then all e-mails and Skype lines/calls will filter through and I will reappear as online.
How can I stay online even when my computer goes to sleep?
