If you’re like me and your MacBook Pro keeps waking up inside your laptop bag (draining your precious battery life), you can force it into “safe sleep” (hibernation) instead by running sudo pmset -a hibernatemode 1 from the terminal. It takes a bit longer to go to sleep, but it also prevents these accidental awakenings, since you have to hold down the power key for a second or two to wake it up.


  1. Thanks for the tip, Andrew. This power drain and non-sleeping behavior has been bugging me lately…
