Why is 10.2.3's Energy Saver Still Dysfunctional?
As an iBook user, I'm continually puzzled by the fact that through three updates 10.2's Energy Saver still isn't totally functional. How so you ask? Well, try to work with the pre-sets in the Optimization menu. Logically, I should be able to set separate optimization types for the battery power and AC adapter configurations. Let's say that I want Best Battery Life for the battery configuration and Highest Performance for the AC configuration. With the AC menu choice selected, I select Highest Performance. Then I switch to battery and select Best Battery Life. When I switch back to the AC setting, I find that it has been changed to Best Battery Life; if I change it back, then the battery power setting changes to Highest Performance too. In short, the most recent preset setting is applied to both. I can't imagine that I'm the only one experiencing this issue, so why hasn't Apple fixed it yet? This problem certainly isn't significant, but it's a nuisance nonetheless.

Got another hour or so left.
<strong>Is it unusual to watch Jaguar eat 1% of battery every 10 seconds? I'm NOT kidding. It says "reserver battery power" at just below 60% too. OS X SUCKS! (battery)</strong><hr></blockquote>
Thats a bug I think with regards to your reserve power message at 60%.
See Apple Tech docos for that
<strong>I thought since OS X pages out more it'd use less RAM and therefore get better battery...
and therefore the harddrive...duh!
<strong>I don't think OS X even with reduced processor speed and dimmed screen gets over an hour on my iBook. Must OS X always be doomed to get less battery than 9? I thought since OS X pages out more it'd use less RAM and therefore get better battery...
What kind of iBook do you have? A clamshell?

Yes Jonathan I see that 0% bug too. Thanks for that link Defiant I'll try this later today.
<strong>So that uses more battery defiant? Does 10.2 have RAM disk implemented yet? I wonder if putting your swap file on that would help?
brad ? could you please ? I'm not confident to explain it myself.
<strong>Wow, I dont understand all these battery woes... I have a new 14" iBook 800 and I consistantly squeeze at -least- 4 hours. 5-6 if im not gaming... ::shrugs:: guess I got lucky?
Yeah, I have a new Powerbook 1GHz and I've gotten six hours (I left it unplugged doing nothing...) but, I usually get 3-4 watching a dvd, or doing just light work... It really saved me when my flight was delayed by 4 hours. I just played Sim Cinema (old school!) for the whole time.
No RAM Disk, and to put your swapfile on a RAM disk it would have to be created at boot, before your swapfile is defined and created. Unless you're hitting Photoshop or some ungodly crappy piece of code, with enough RAM you shouldn't even be hitting the HD.
I'm an iBook-ist with a rapidly draining batt too, by the by. I tried the remedy before and still find that the battery plummets like a rock regardless of settings.
OS 9.x it ain't when it comes to batt life!

Anyhow, sorry guys, but I really don't have a solution for your battery woes. I don't own an Apple portable nor do I have someone nearby that does. My best suggestion is to try the link that Defiant posted above. It seems to have had success with a number of users.
As for OSX's swap file, putting that on a RAM disk would be a ridiculous idea. Basically you're saying that when the system runs out of RAM and needs to hit the drive for memory that it should hit the RAM disk instead. Uhh, does anyone else see the problem here? If it runs out of RAM... it has nowhere else to go! Get it? The solution here is to just buy more RAM and pack as much as you can into your Mac.
