Using Powertop to save Battery Power (Part 2)

Continuing from the entry Using Powertop to save Battery Power (Part 1)

How do we reinstate the optimised settings for ac-power? I suggest we put the settings that take advantage of AC-Power back into the /etc/acpi/ac.d

# cd /etc/acpi/ac.d # touch 16.optimsation.sh
# chmod 755 16.optimsation.sh
# vim 16-optimisation.sh

#------------------------------------------------------
echo 500 > /proc/sys/vm/dirty_writeback_centisecs
echo 0 > /proc/sys/vm/laptop_mode
hal-disable-polling --device /dev/scd0 --enable-polling
ifconfig eth0 up
iwpriv eth1 set_power 1
#-------------------------------------------------------
