So I got a new White MacBook a few weeks ago, and it isn't sleeping properly. When Im using it and the battery gets low, I get the message that it is running on reserve, and It will go to sleep in a few minutes. I keep using it, and turns off, but the light stays on solid for about 10 seconds while it is copying the RAM to the HD for the "Deep Sleep." Then it just turns off instead of breathing. To wake it back up again I have to plug it in and press the power button. I was under the impression that it is supposed to enter normal sleep (I.E. the same as when you close the lid) when the battery gets low, and only enter "Deep Sleep" if it stays asleep too long and the battery dies completely. I have calibrated the battery a few times, and it doesn't seem to help. Any ideas?
