<div>Nicely done, Godfrey, and congratulations on tracking your problem down so well. I hope you had a great Easter with your family and can rest on your laurels a bit, now you are well on the way to being a Linux guru!</div>

<div name="quoted-content">Hello folks,<br/>
<br/>
Finally solved problem of getting daughter's new laptop to shutdown and<br/>
completely power off. Spent long time going through all the askubuntu<br/>
pages and tried all sorts of ideas from modifying parameters in grub to<br/>
blacklisting various modules.<br/>
<br/>
The one that worked on this machine was to edit<br/>
modprobe.conf/blacklist.conf and add lines to blacklist two modules -<br/>
blacklist dw_mac<br/>
blacklist dw_mac_core<br/>
<br/>
After rebooting, the machine now powers off when I select shutdown.<br/>
<br/>
Maybe when I have some spare time I will look at those modules to try<br/>
and find out why they cause the problem, but for now I am happy to have<br/>
it fixed.<br/>
<br/>
