[OS X] Better battery life while on the road.

After being annoyed for the last year that my MacBook Pro was eating up my battery life while in hibernation, I finally chose to investigate the matter further. Several articles describe the pmset command (here is one), but to make a long story short I wrote a script that will let my Mac enter hibernation mode (suspend to disk) immediately, without altering the settings (permanently at least).

I uploaded it to pastebin to increase the chances of it being spread. Link.

It should be pretty self explanatory, but to sum it up it does the following:

  1. Back up your existing hibernation settings
  2. Sets new ones that will suspend to disk and then cut power (not keeping any power to RAM)
  3. Hibernates (and shuts off)
  4. On power on, it restores the previous settings

If you find it useful, drop me a comment. Maybe I could make this into a small systray utility some day if someone finds it useful.

    This is an excellent utility. You may want to leave instructions for the laypeople as to how to make this app run (I had no issues, all good). Thanks!
