    Of course. Sometimes, the chipset consumes double or even quadruple the energy used by the cpu.

    I think you are right. My chipsets is SiSM672 and the discharge rate is more than 22W even everything is off. I read many reviews that SiSM672 notebooks have very poor battery life. Even the system has the same specifications with the intel chipsets platform, SiS chipsets only has 60% battery runtime of their Intel counterpart.

    Wish that I knew this fact earlier so I would never buy any notebook with this darn SiSM672 chipsets!!

    p.s. Is SiSM672 for desktop? It just add an "M" for pretending being a mobile chipsets?

    I think this shouldn't be here. Mods, please move this to the right forum.

    Moved to hardware forum.

    There is data on the VIA chipsets here. The VX 800 in the Samsung NC20 ( review here) is quite economical on idle but starts to sup power when under load. However, it is also more powerful than the Intel 945 chipset.

    I cannot find the TDP of SiSM672 chipsets. I doubt the high discharge rate on idle is because of the chipsets but not the CPU.
    Here's my last thread about the high discharge rate of my notebook
    http://forum.notebookreview.com/showthread.php?t=364568&page=2
    And now I guess replacing my CPU wouldn't help much. SiS chipsets is too bad.

    Ah! Back to that problem again.

    I tend to agree with your conclusion.
