This is a reply to Jos Collin's weird comment.

What kind of a comment was that? Just waste your battery because - hey! -
it will die on you anyway at some point in the future. How is battery life
NOT important for a MOBILE COMPUTER?!? The whole point of a laptop IS to
use its battery efficiently so that you can be independent power-wise at
least for a limited amount of time.
