Hi! two weeks ago I reinstalled OSX Lion on my late '09 MacBook Pro, because of its performance problems. Now, after I used Time Machine, everything works fine, accept one thing: Wenn my Macbook is connected to my MacSafe, it won't turn to sleep mode, when it's closed. When the MacSafe its unpluggt for just a second, it's turning to sleep-mode as normal and the front LED starts to "Breath". I couldn't find any wrong adjustments.
