How does OSX come out of sleep so quickly? Its really clever. Also, how does it sleep so quickly too?

I've read the processes are multithreaded.
I've heard that the sleep isn't so "deep".

I doubt that. It barely scratches the battery indicator when sleeping over a weekend.

Really? That's interesting because I am thinking about buying one of the new iBooks with MacOS X.

Hmmm ... no so on a Pismo.

Just a forty five minute commute home drains my battery so it needs half an hour to recover.

The CoreGraphics server (equivalent to the X server on traditional unixen) is the first thing re-started when waking. Other services take longer to start up; so if you were browsing the internet before piutting the machine to sleep, and click on a link immediately after waking, it would take a bit before things got going.

At least, that's what a guy from Apple told me.

Stephan B. Wessels replied on 19 June 2001:

Interesting. I have one of those new PowerBook G4s with 512MB RAM and run OS X. Sleep mode really does take a minor hit on the battery. I never shutdown. At night I close the lid. In the morning I open the lid and resume working. Not only is it really fast at this, I don't recall ever seeing any appreciable battery drain as a result. I average about 3.5 hours (I've actually gotten more than 4 hours use typing memos) between charging with continual use.

I have one of the new iBooks with OS X, and it will not wake up from sleep while booted in X. Removing the battery for a minute is the only way I've found for recovering it. For this reason, it stays in OS 9 most of the time. If you find a solution to this problem, I'd be interesed in hearing it.

This is a known problem. Loads of people have been having it. I'm sure Apple will be addressing it with the next update.

Quite agree. My new iBook can go for about 4 hours on a single recharge and the sleep in OSX is indeed only a minor drain. I remember my older iBook (300MHz blueberry) and OSX used to run out of juice regularly, and I had to restart - but maybe that's got something t do with me using my new iBook more... ;-)

I should have included more info, I guess. I'm running a TiBook. Very interesting discrepancy.

On some machines it's probably from better VM. Many machines don't really sleep.

I have a couple month old battery in a WSI, leaving it asleep with OSX overnight left it with about 40 min charge remaining, say half was used up.

What do you mean 'big crap snip'? Its my public PGP key. I want to distribute it. How else would I?

I mean "I don't leave my iBook on the battery when it's asleep cos it runs low so quickly," or something to that effect.

There is good reason for guidelines, Craig.

Flouting those guidelines isn't too bad in itself. But being offensive when pulled up on it? Hmmm.
