I am looking to see if anyone out there has any kind of a hack for MacOS X that will allow you to put a powerbook into a "deeper" sleep. That way I could have the battery savings that my powerbook got in OS 9 while asleep. I could care less about instant wake up, I have to charge my powerbook every few days right now!

Wow, I never saw that option. Thanks a bunch...

But back to the topic, I remember seeing a hack to turn off sleeping when the lid was closed (you had to compile a kernel extension, or the kernel itself, don't recall which) so putting a pbook into "deeper" sleep should be possible through a similar "hack".

Shuting down, and then starting up takes about 60 seconds for me (on a good startup), so a wake from sleep that took 15 would be much better. And the battery savings would be great! The current sleep rather sucks at saving battery life (it eats about 20% in an 8 hour period of sleep).

Kupan I doubt that there is a deeper sleep mode. If there was one apple would have utilised it in some way. In preference tab to choose between the 2 sleeping modes or something like that. So as shrink said I think the best thing to do is to shut down your machine. Try also to disconnect any equipment that suck power from the powerbook like external mouse usb keys and stuff like that. If I disconnect my intellimouse mouse I get much better battery sleep consumption.

Think about what you're saying, for a second. The "hack" you mention doesn't add or remove any sort of functionality to the OS. It just changes the circumstances that can trigger existing functionality (in this case, sleep).

What I would not be opposed to Apple introducing, however, is functionality similar to Windows's hibernation, either through OF, or implemented at the OS level.

I guess I may be in the minority, but I get the same 'sleep battery life' in OS X as I did in OS 9

What you want is 'Suspend to disk', also known as 'Hibernate'.

Write the memory contents out to disk, and turn off. Start up, copy it all back in, and start running.

I don't know if OS X supports it.

It doesn't.

I'm with Placid Casual here. I sleep my PB17 all of the time, and the daily battery loss is only 1-2%. If you have to charge to full every few days or so, your battery may not be calibrated correctly, or may have problems within it.
I dunno man...

Can't remember who told me this one but option-alt and the eject key puts the computer into some form of deep sleep. Maybe it's just a normal sleep but the quick key is a handy one.

I'm sorry I don't understand. Option and Alt are the same key (at least on a Mac). What is the key combo for sleep?

Ooops sorry ment apple-alt and eject key...
