Get your MacBook to sleep smart

Oh mirror, mirror, on the wall

I've been meaning to blog about SmartSleep ever since I discovered it early this year.

I almost never shutdown my MacBook Pro, I always send it to sleep. Faster wake up time, this behaviour makes sense on a laptop. Only, it can take ages for the MacBook to actually go to sleep. Check how long it takes between the moment you close the lip, and the power led start pulsing. Ages.

This is because your are not only sending your computer to sleep, but into hibernation too, which is the default behaviour. Sleep is fast, it is the hibernation which takes time as it is saving the MacBook's state on disk. So how can we change that? This is where SmartSleep kicks in.

SmartSleep is a preference pane that dynamically sets the sleep state of your machine.

SmartSleep let’s you select each select sleep state. Additionaly the new SmartSleep state 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.

This preference pane runs flawlessly, to a point you forget it's installed - until you start working on a MacBook that doesn't have it.

A must have if you own a MacBook.

Hey David, thank you for the tip! I just installed it on my MBP... Hope it will help me save my battery...

@Yannis I'm not sure it'll save battery, but your MBP should go to sleep much faster when you close the screen ;)

Installing SmartSleep on my Dell Mini 9 (10.5.8) fixed its sleep problem :)

How does Smartsleep react to a situation when you close your Mac at say 22% battery power and let it closed for a weekend? Is it that smart to wake up and hibernate, or does the battery run out of power?
I'm just considerig an install. Thanks!

@grj I'm not sure, I need to test a border case such as the one you mention.

Try contacting the author, he might have an answer?

About

Hello, my name is David Roessli. I am a freelance web designer and developer based in Geneva, Switzerland.

This weblog is an nth attempt to solve my multiple online personalities and weblog/rss feeds burnout issues. (more)

Words

I have been contemplating the idea of upgrading my desktop Mac since this spring. The latest 27" iMac (Quad-Core) seemed the perfect candidate, but the release of Apple's 27" Monitor last September made me stick with the Mac Pro...

Music

The autopsy of an iconic album cover picked up on Kottke.org. A stacked graph of successive radio signals from pulsar CP 1919, in a 1977 astronomy encyclopedia that originated in a 1970 Ph.D. thesis. Fascinating <3...

Pictures

Check out my latest Flickr ramblings. Mostly day to day cameraphone pictures stolen here and there.
