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 consumtion after this tipps: 11-13 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.

I will get into deeper later.

Let's start:

Set wlan and bluetooth off (hardware switch)

Deaktivate the touchpad.

My Bios Settings:

Bluetooth off Modem off //have to look up other things//


Script to save power

This script reduce the power consumtion to 13-16 watts

Save this script as /etc/rc.local

Then modify /etc/kde4/kdm/Xsetup

and add:

exec /etc/rc.local

before exit 0

The script:

// need a place to upload permanently //

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
