grand unified power management?
have an ancient thinkpad 570e that is (hopefully) in the middle of a successful debian etch install, 2.6.12 kernel. computer has apm; afaik, no acpi support. under mandrake, i got maybe 10 minutes of surfing with a pcmcia card. that was without any power management. hoping to improve on that. and yes, i realize that my battery's probably junk. seems that there are a lot of ways to save power--what are the most important, and how to implement them at boot time?
display--haven't looked into this as my screen has a slide switch to dim
cpu--not sure if any of the throttling (cpudyn, etc) apps will work on my p3; i'll give it a shot.
hard drive--fooled around a bit with hdparm with some success. looking to add this to an init script
pcmcia card--haven't had luck configuring power mgt on this. whenever i set through kde or iwconfig, it doesn't seem to take. i'm wondering if it's a driver issue.
also haven't tried laptop-mode-tools. so what's the magic combo of settings/programs that will take care of all aspects of power management?
