This is what I got:

Before this battery time is <2h.
After this it is prolongued and I have estimated it to be 3.5h.
Didn't measure it exactly.

I want to know if anyone has more info on some options available in bios.

First of all, I am able to enter bios (Insyde H20) advanced mode (press 
F10 followed by A as fast as possible) and there are options to choose 
integrated or discrete graphics or hybrid. But unfortunately choosing 
discrete is not possible because the bios gets stuck with a black screen 
on saving changes and I have to power cycle and after that the changes 
are lost. Choosing integrated is not persisted. After reboot it is again 
set to hybrid. It seems that these advanced options are locked and not 
usable.

There are few other bios options that might be related to this (looking 
at the name PEG), but I was not able to find info on them and what they do:
ASPM Enabled
PEG Force x1
Auto ASPM

In fact my problem is a different one :)

I would not like to turn off ATI, but the opposite - I would like to be 
able to force to use it.
As it is now, I can not use it at all no matter if turned off (via acpi) 
or not Ubuntu always uses Intel integrated.
I do have 3d effects (compiz) but I need better opengl support (WebGL etc).

I have Ubuntu Maverick.
Using the Ubuntu recommended proprietary drivers results in an error 
that the graphics is switchable and unsupported and that I have to turn 
off the discrete adapter.
Using the latest Catalyst 11 does not present any error but I was not 
able to get screen output (only black screen with a small _ (underscore) 
in the top left).
Using the latest xedgers pushers updates still does not help again I am 
on Intel.

No matter what I tried, I am either on Intel or fb safe mode, and I am 
never able to get a display from ATI.

I tried Ubuntu Natty two weeks ago, and it was not stable enough (plus 
ATI did not work) so I reverted back to Maverick.
