ADSL setup and Battery Problems

[Jason Nelke]

hi.
im new to linux and the list. I just recently installed yellowdog 4.0  
on my eMac, which was cumbersome enough, but my problems now are that  
i can't get my ADSL connection to work, and for some reason Yellowdog  
keeps telling me my battery is low and about to loose charge.  
However, my computer is a desktop. Can anyone help with these two  
problems?
thanks in advance,
jason
