Hi, I've noticed that my Macbook Pro mid 2009 (with renewed battery, 2 years old) suffers from battery drain in sleep mode. The battery seems to be OK according to Coconut Battery app: Yesterday I look for a possible solution and I used this command: 'sudo pmset -a hibernatemode 25' Then I filled the battery, rebooted the Mac, made a CMD reset, unplugged the Mac and let it enter sleep mode for 19 hours. The battery was at a 80% (from 100%). The result of a 'pmset -g' is: Active Profiles: Battery Power -1 AC Power -1* Currently in use: womp 1 halfdim 1 sms 1 hibernatefile /var/vm/sleepimage networkoversleep 0 disksleep 10 sleep 30 hibernatemode 25 ttyskeepawake 1 displaysleep 10 acwake 0 lidwake 1 Can anyone help me to improve my battery life during sleep mode? I'm absolutely not an advanced user, but I can follow the instructions quite good, if they are detailed. Thanks a lot!
