Hello good mac people, i have a macbook pro core duo, 2.0 ghz, that seems to not really go to sleep. i close the lid, and it seems that the battery drains. i listen to the computer, supposedly asleep, but the fan seems to be still running, even the processor... and then later, the battery is drained! what should i do? a firmware update? thought it was updated? a genius bar visit? r.
