...Increasing Battery Life...
Along with the other power saving ideas mentioned in this forum... You might want to try turning OFF the "AUTO" mode in the display brightness setting, and then manually set your display brightness to the absolute lowest level...
This is still plenty bright on my unit... and this has made a considerable increase in my battery life...
Let us know if this noticeably helps with your battery life...
