Save power with Ubuntu 9.04 (Jaunty Jackalope) on a ThinkPad T400
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
