Hi
// have to read wiki syntax to format correctly//

Basic information
I have Thinkpad T400 WC8......
9 cell battery now 60% last 4.37 h
Idle consumption after these tips: 11-13 watts, before the tips I used 30-35 watts
I use the ATI Card with the fglrx drivers, unfortunately they 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 daemons you don't need with rcconf
Set wlan and bluetooth off (hardware switch)
Deactivate 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
Virtualisation off
Dockingstation off
Script to save power
This script reduce the power consumption 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 these parameters(add after -q with a space after q):
-m 2 -l 20 -u 70 -s 300000
Powerdevil settings
Powersave Profile Settings:

Dim after 1 min
Idle for +20 min shutdown
Lid: lock screen
any Button: Show logout dialog

Screen Brightness 75 %
enable display power management
standby 3 min suspend 6 min power off 8min
cpu:
scaling: userspace scheme: powersave
Guidance PowerManager
Lock screen after resume

drops below 10 min --> shutdown idle more than XXX do nothing cpu freq: dynamic (changed from powernowd then) Lid: lock screen
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
