    I'm posting in this forums becuase it seems to frequently discuss undervolting...Mods feel free to move if you think its in the wrong place.

    So I just bought my wife one of those MSI wind U100s (supercheap) and I was wondering if it was worth attempting a CPU undervolt to save battery? The Wind comes with a built in underclock fuction on the F10 button to increase life, but I was wondering if I could stretch it further...

    Try it, there is an undervolting guide in the Hardware section, just search in the forums for it.

    Edit!: WOW thats handy, just typed the word and there is a link to it, haha.

    The Atom CPU uses insignificant power as compared to the rest of the system. Undervolting it will not produce a significant change in battery life.

    ^ Yea it uses like no power, I just looked up the specs, it has 2gb of ram, an Intel GMA 950 and a normal HDD, there is really nothing to be done with the system that will gain you more than a 20 second battery life gain.

    A SSD would improve battery life marginally, but honestly its not getting any better.

    Its possible the Wind's undervolting button does more than just undervolt the processor...

    Intel Atom has a 2W TDP. Undervolting might reduce it to 1.8W, saving you maybe 5 minutes of battery, lol. It doesn't even need a heatsink for crying out loud!

    Moved to the Hardware Components forum.

    And I agree with the above - undervolting the Intel Atom won't yield you any noticeable battery life increases.
