Hello Folks, On my 500MHz iBook running OS X 10.3.5 my battery life is only lasting about an hour these days. When this computer was new, I could get 3.5 hours in OS9 mode. Now, it seems to get shorter and shorter with each updated version of OS X. I can push a few extra minutes out of it by keeping the screen dimmer, and I already "refreshed" the battery using the NVRAM trick Dan mentioned on this list a couple weeks ago. Is this just normal for an older model iBook running the newer OS? Are you getting similar results or have suggestions to bring this battery back to life? Thanks, Tom
