When I used FC4 on my old IBM X40 (Intel Pentium M Ultra-Low Voltage CPU, clocks from 1.00GHz down to 266MHz) I had to jump through a bunch of different hoops to get CPU frequency scaling working correctly. Once I got that working the machine used a lot less power. There was some cpufreq utility that needed to be installed to make the cpufreq LKM available. Then I needed to run some obscure "insmod cpufreq" command as root. That was FC4, it could have changed. It might also vary based on CPU. I seem to remember my chip not being included in the default set of frequency scaling chips. If there's a "laptop" kernel or a "laptop-mode" package you might want to install that. I remember a situation (can't remember the distro) where simply installing a package named "laptop-mode" roped in a whole bunch of goodies as well as configuration files that enabled them. Good luck! Also likely candidates for such a poor battery life: o The hard drive might not be spinning down while not in use. There's some setting you can use in /etc/fstab to change this. Try reading through man fstab for more details. o The CD drive might be goofing off. If there's a disk in there, that'd be a good suspect as well. o The wireless card might be using inoptimal power management schemes. -- Registered Linux Addict #431495 http://profile.xfire.com/mrstalinman | John 3:16! http://www.fsdev.net/ | http://lordsauron.wordpress.com/ --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Linux Users Group.
