Ever since I upgraded to 10.3.6 i have had the following two problems: 1) The computer is running hotter than normal, and so much so that the fan is running 60% more of the time... and that is causing the battery to run out very, very quickly... 2) The 12"PB will not go to sleep automatically. It will sleep manually or if I close the lid. I called Apple and they told me #1 "was normal" and couldn't help me with #2. I have reinstalled 10.3.6, but with the combo version, but it hasnt changed anything. Anyone else having these issues?
