How to turn off deep sleep?
Authored by: killee on Oct 19, '06 07:24:53AM

I upgraded from an old 12" Powerbook G4 to a new MacBook Pro... I really notice how much longer the MBP takes to sleep when I close the lid. My old powerbook would sleep in under 3 seconds... the MBP takes at least 20 seconds!

I really don't like this new feature on the MacBook Pro, and I don't want it to write its memory to disk each time I close the lid. I rarely, if ever, leave the computer in sleep mode and let the battery drain... I use my computer all day, everyday.

How do I turn off the deep sleep feature? I want it to sleep faster than 20+ seconds! I wish it would work more like my old powerbook did. [shrug]

thanks,
Kelly

How to turn off deep sleep?

Greetings.
If you want to disable the default "fall back to hibernation if ever the battery was to run out of power" behaviour (and therefore make your computer enter sleep quickly), please do the following.
Open up a terminal, and type the following command:
sudo pmset -a hibernatemode 0
You will need to enter an administrator password.
