Tips For Extending Linux Battery Life

Offered without comment.


  • mount file systems with the noatime option:
/dev/hda1 / ext3 defaults,noatime 1 1
  • turn off atd, and run at once per hour out of /etc/crontab
00 * * * * root [ -x /usr/sbin/atrun ] && /usr/sbin/atrun
  • make syslog lazy about committing to its file by prefixing the filename with a -
*.info                  -/var/log/messages
(Found somewhere:)
  • configure /etc/cpuspeed.conf, if supported
#OPTS="-i 2"
OPTS="-a /proc/acpi/ac_adapter/*/state -t /proc/acpi/thermal_zone/*/temperature 75"

This is a collection of techical information, much of it learned the hard way. Consider it a lab book or a /info directory. I doubt much of it will be of use to anyone else.
