I'm also looking for manuals that will let me repair LCD monitors myself.
Simply lower the screen brightness from 100% to 70%. Doing that will save you 10 watts of electricity per hour. The reason for this is that 66% of the electricity used to run a monitor goes to light up the screen. Lowering screen brightness will save more power. This technique works with both laptops and LCD monitors.
Turn it off and go outside. Site below is pretty good for diy lcd repair
