Power Consumption

Use powertop (sudo apt-get install powertop) to find out ways to reduce powerconsumption

• Wifi powersaving is important (2W), enable with "sudo iwconfig wlan0 power on"

One way of reducing powersaving is to add entries to /etc/rc.local so they get loaded at boot.

Sample /etc/rc.local for Timeline Laptops

#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

/sbin/iwconfig wlan0 power on

exit 0
