I don't know about the battery issues, but I have an old Clevo/Lapnote
laptop that also required hard power-off. This is what worked for me (in
both Gutsy and Hardy):

gksu gedit /etc/modules

Add the following line:
apm power_off=1

Save and shutdown, then reboot again to make sure that it is working.

If that doesn't do the trick, then check out the refs below for added ideas.
