When does hibernate mode start?
Sometimes, my MBP holds sleepmode for a great amount of hours (flashing led) and other times the MBP seems to be turned off, but when opening the display, the MBP seems to wake up from hibernate mode (sleepmode without flashing led). Is there a special rule behind, when MBP starts hibernatemode? I heard in another forum, that after 5 hours sleeptime the MBP changes to hibernate? Is that correct? Why does this not always happen after 5 hours?
Thanks in advance
