Today I do a measurable about it. First I using 2.6.12 without dynamic enable and unplug the AC power, I check the /proc/pmu/battery_0, like this. -- flags : 00000011 charge : 907 max_charge : 2863 current : -987 voltage : 10950 time rem. : 3600 -- I only intresting with current, that show the system power load. When I enable dynamic, The current can low at -900. So, It works. :> 2.6.12 + suspend2 + ck3 + dynamic http://soulinfo.com/~hugang/kernel/linux-2.6.12/ -- Hu Gang .-.
