So I just upgraded my 2012 Macbook Pro to the new Yosemite operating system and when I charge my mac, the whole computer goes into a standby mode. I usually charge my mac overnight and when I wake up to unplug it, I hear the motor or something come on (sorry not good with technical terms). Then when I open the mac, I have to use the power button for it to turn on rather than just hitting any key. Is this new to the operating system because my mac hasn't done this before and I just want to make sure it's normal. Thanks
