Hi

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)

My Bios Settings:

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

Script to save power

Save this script as /etc/rc.local.

Then modify /etc/kde4/kdm/Xsetup

and add:

exec /etc/rc.local
