DESCRIPTION
SmartSleep is a preference pane that dynamically sets the sleep state of your machine. It's a successor to Hibernate.prefPane.

The Problem - Your MacBook or MacBook Pro knows the following sleep states:

  • sleep: machine will go to sleep only (saves state in RAM only, battery keeps RAM contents)
  • sleep & hibernate: machine sleeps and hibernates. (default)
  • hibernate only: machine will go to hibernate only. (saves state on disk, battery will not be used)
  • Just sleep means that the notebook will go to sleep fast, but you loose the ability to change the battery as the battery is needed to keep the contents of the memory (RAM).
  • Just sleep and hibernate will wake the computer fast, but sleeping will take ages as the contents of the memory are saved to disk before entering the sleep.
The solution - SmartSleep lets your notebook just sleep while the battery has a high level. If the battery level drops below a certain point ( default is less then 20% or 20 minutes ) it will switch to sleep and hibernate. So you have the best of both worlds.

TACITUS  Including a readme file would be a good idea.

What exactly does this install apart from the prefpane? The smartsleep function seems hit or miss. I think it works if I manually put it to sleep, but if it goes to sleep automatically when the battery is low it doesn't seem to hibernate despite being told to. All RAM data is then lost when the battery is changed.

Looks a good idea and has potential, but it possibly needs a bit more work.

TVOPDX  I like the idea of this. And it does put my MacBook Pro to sleep faster and nicer than the system itself. However, I find that my battery only operating time is cut in half. When I check my energy saver settings, it's always set to custom. When I force it to Better Energy Savings, it shifts to custom without any action on my part. As a consequence, the three plus hours I used to get with careful energy management has dropped to a measly 60-90 minutes. SmartSleep has a ways to go before it will work for me.  (Version 1.0 (1531))

JOLLY AKA PATRICK  Hmmm sounds weird. Send me a mail and I try to solve the problem.

Can you set the hibernate level in the shell ? (pmset)

BOBJAZZ  I can't get this to work in "Smart Sleep" mode. It won't change the setting from sleep only to sleep & hibernate (or vice versa). It says it's updating, but just comes back with the setting the same as it was last set. Even if I manually change the sleep & hibernate level, it updates and then comes back with the setting the same as it was before. I've tried fixing permissions, that didn't work. I've also tried 3 different versions now, the last beta, build 1529 and the latest, build 1531. They all behave the same. I'm running 10.4.10 on a 1.83Ghz Core Duo MacBook (2006) with 2GB of Ram. Anybody know what's going on?  (Version 1.0 (1531))
