Hi, first, thanks for the tutorial! I am trying to figure out why my win7 x64 on HP 8510w laptop is suddenly taking ages to go to sleep, and sometimes also to wake up. I've made a trace http://dl.dropbox.com/u/153770/standby_BASE%2BCSWITCH%2BDRIVERS%2BPOWER_1.zip From my looking at it, all i see is that ntfs.sys and fltmgrs.sys are doing a lot, but nothing much I can do about that, I guess? The interesting thing is that from the graphs it seems like the disk is doing a lot, whereas looking at the disk light it is doing sth in the beginning, but then there is a long stretch where it's doing nothing and I'm not sure if this is in the trace. Any help would be appreciated.
