Just got a replacement Macbook Pro 13" this week for my old Macbook; however, it drains the battery at an incredible rate if I put the computer to sleep. About a minute after I close the lid, the fans cycle up to full speed and stay that way until the battery drains ~ 4 hrs. I've done a hardware check using the install disks but no errors are reported. Just to check - has anyone else had this/found a solution? I'd love to get it sorted so I don't have to go to the Genius Bar.
