    Until there is some better information I would assume similar to the E6400 with a similar configuration. ie 4 to 5 hours with a 6 cell battery.

    Not bad battery life from a 6 cell imo....

    Did a tiny bit o' research...

    I did find that the older P-series (Penryn) in the E6400 have a TDP of 25 watts, but the newer core i5 mobile processors (and the available dual-core i7) have a TDP of 35. So, this is a negative in power usage. However what needs clarification is whether this the max TDP accounting for power usage when turbo mode is enabled. So, I assume the average watt usage will be much lower than 35 watts, when performing very light tasks such as web browsing, word processing, etc.

    DDR3 RAM is rated for less voltage than DDR2, but I *assume* that this difference is negligible.

    The older nVidia Quadro NVS 160m has a TDP of 12 watts. However, in the E6410 the NVS 3100m has a TDP of 14 watts.

    So, this being said, I'm not quite sure how the E6410 could be an improvement over the E6400 power-wise, apart from what I have mentioned here.

    You also need to account for the fact that there is the memory controller and IGP on board the chip.

    Well, for one thing, TDP is not power consumption. TDP (Thermal Design Power) is a measure of how much _heat_ a component puts out at maximum load, and thus how much heat the cooling system needs to dissipate. Thus, depending on the efficiency of the component involved, 2 components with the same TDP could still have vastly different power requirements.

    As well, for the new i-series chips, what used to be the northbridge (the memory controller) on the motherboard of the old C2 series chips is now integrated directly into the CPU chip itself. Depending on the exact chipset, the northbridge could easily account for 5-10 watts of TDP (PM45 is about 7 watts, for example).

    Anandtech has made a useful comparison of power consumption.

    I usually like Anandtech articles, but I'm less than sure this is a good test in this particular instance. First of all, they're comparing a pre-production Asus K42 to a HP (exact model not listed). Even though they tried to keep things as similar as possible, simply setting equal brightness levels on both machines almost certainly won't result in equal power draws (since I kind of doubt both machines use the same screen). Still, it's probably not bad for a ballpark figure, but... enh.

    Probably in a couple of months when the i7 ULV comes out?
