    i have an asmobile s37s model with a 2.2 ghz core2, 2gb ram, 160 7200 rpm, 8400m nvidia card, built on santa rosa platform with 3945abg wireless, intel turbo memory and bluetooth.
    now a realize this is a powerfull setup, but a have 6 cell 5200 mw batteri but can it really be true that i can only press 2 hours of battery time out of it, if im lucky and using battery saving mode.
    Read that a collegues have a lenovo with a bit smaller hardware but with the same battery capacity and he is managing to push it to 5-6 hours!. And the other collague has a mac. Yeah you probably guess it. Very long battery time but with (on paper) the same battery capacity.

    any one who can tell me the diffence between batteries and if it can be true that i can only press 2 hours from it.
    I have an idea about that having a nvidia 8400 gpu with a nvidia driver it does not use the powermizer function that well. I run vista so it is suppose to run the powermizer function for itself. But does it?

    Asmobile is an ASUS. ASUS are known for relatively poor battery life in recent models.

    But anyway, make sure that the CPU is speedstepping and the GPU is also in powersaving mode while on battery.

    Also keep your BIOS and ACPI drivers updated.

    You are not alone.

    Looking at the specifications that you mention, 2-2:30 hrs is normal in terms of battery life under Vista. The key reason for this is the fact that you are running a discrete graphics card and these are power hungry. While you haven't indicated your friend's Lenovo specifications, the fact that he is pushing it to 5-6hrs even with Aero enabled would suggest that he has an integrated graphics card (Intel X3100).

    I have 2 Lenovo laptops - one with an ATI discrete graphics card and other has the Intel X3100 graphics card - same exact times with battery.

    You will see this exact same behavior irrespective of laptop or operating system. It's not manufacturer specific or software specific.

    If you compare an Apple MacBook Pro with and without integrated graphics, the same holds true...that is where technology is at today.

    Now, having said all that, you should understand that there may be other hardware components on board your laptop that may be more power hungry, as well as the fact that the power management driver being different between ASUS and Lenovo will have an impact.

    Hope this helps...
