Hello List, I'm using an acer TM 521 TEV. APM support is integrated into my kernel. My problem is: When I close my notebook it puts itself to sleep, fine. But when I want to use the hdparm -S to let my harddisc spindown when it's not in use it alway wakes up after about 10 sec. On my old system with suse it didn't do that, how can I get it working ???
