when I try to set the critical battery level settings for any power option I am getting weird and inconsistent results. If I set a power level the previous setting will return immediately upon exit. IE, if it is set to 98% and I set it to anything (like 50%) when I leave that entry it goes back to 98%. Sometimes it will change to 100%. It doesn't matter what the low level is set at. If I set the low level at or lower than the critical level it gives me a warning then changes it. If I set the critical level higher than the low level it gives me a warning but doesn't change it. If I set it lower than the low level it still won't change it. How do I beat W7 into submission??????????????????
