guys experiencing power management issues, please capture system.log for this scenario (it is in console, copy-paste only the lines that are related to 'entering into sleep mode' and 'returning to normal mode') write down the timestamps of each of your steps e.g.: 1. boot. 12:00 2. boot finished, launched itunes: 12:10 3. chosen 'sleep' in apple menu: 12:15 4. mac went in sleep mode: 12:16 5. woke up mac: 12:18 6. ... if you are getting shutdown problems, capture the logs, too don't send/attach -whole- system.log: it might be 1-2Mb - I only need just its part that is related to the problem. for instance, if you boot at 12:00 and test power-down issue around 12:15, the part of the log corresponding to this interval is sufficient for me E.
