Well? haha
Will there be any signifiant difference or not enough to really worry about it?
And while I am at it, would shutting off the back lit keyboard have any effect?
Thanks!
You can not do this as this is the same backlight that your screen uses.
--carry extra battery
Really the only way to increase to increase the battery is to do the fallowing:
--Turn off wi-fi
--set the back light to turn off after 5 min
--carry extra battery
