I did not investigate this further, on why the RTC-module is doing this. A 
week ago, we had this discussion on the list with the Acer TM-63x not 
powering-off. As mine did all the time, I suggested first to update the 
BIOS. But later we found out, that it was the RTC-module, that I did not 
use. BTW the generic-RTC-module is usable. My problem was, as I tried to 
reproduce this finding, it corrupted my ext2-filesystem. As I need this 
notebook for my work, I did stop going deeper into this... for the moment.
