I have gone through an iMac and a Macbook in the past ten years. After having my Macbook for 4 years I decided to invest in a new Macbook Pro 15 inch. I bought my Pro and with Time Machine passed all of my info to the new one. I am starting to regret it because it is the only explanation I have for my problems. My Pro is 20 weeks old and my battery is already down to 91% Health(verified with Coconut and iStat Pro). My battery does not last close to the 7 hours, I would say it is around 4 hours of just using internet and Mail. Whenever I use Skype or iChat, my fans rev up so much that I have to put the volume to the max to hear the other person. I constantly had these problems in my older Macbook and the only explanation that I have is that when I passed all of my info to the new one, that same thing that caused the fans, and temp is now oing the same in this one. I see no other reason for this. Could someone think of a solution? I really appreciate the help and sorry for writing too much. If someone needs more info in order to help me out please do not hesitate to ask me.
