Basic information
I have Thinkpad T400 WC8......
9 cell battery now 60% last 4.37 h
Idle consumtion after this tipps: 11-13 watts before th tipps i used 30-35 watts
I use the ATI Card with the fglrx drivers, unfortunatelly the have no option to save power.
I use powernowd, Gudiance Power manager and KDE4.2 powerdevil.
4 Gig RAM 2.26 GHz 250GB/5400
Hibernate and suspend work (sometimes, crap fglrx driver)
Let's start:
Stop deamons you don't need with rcconf
Set wlan and bluetooth off (hardware switch)
Deaktivate the touchpad.
My Bios Settings:
Bluetooth off
Modem off
Wake on lan off
Flash over lan off
Serial port off
Always USB off
CdromSpeed silent
Virttualisation off
Dockingstation off
Script to save power
This script reduce the power consumtion to 13-16 watts
Save this script as /etc/rc.local and do chmod +x on it
Then modify /etc/kde4/kdm/Xsetup
and add:
exec /etc/rc.local
before exit 0
The script:
Modify the xorg
Modify like this:
Section "Device"
Identifier "Configured Video Device" Driver "fglrx"
......
Option "DynamicClocks" "true" Option "PowerState" "1" BusID "PCI:1:0:0"
EndSection
and
Section "Monitor"
Identifier "aticonfig-Monitor[0]-1" Option "VendorName" "ATI Proprietary Driver" Option "ModelName" "Generic Autodetecting Monitor" Option "DPMS" "true"
EndSection
Use powernowd
install powernowd
Then modify /etc/default/powernowd
with this parameters(add after -q with a space after q):
-m 2 -l 20 -u 70 -s 300000
Powerdevil settings

Blacklist
echo "blacklist pcmcia" >> /etc/modprobe.d/blacklist.conf
echo "blacklist yenta_socket" >> /etc/modprobe.d/blacklist.conf
Well good luck and have fun i think if you use the intel card you can additionally save 3-5 watts
