    Limit disk drive access by all programs via caching to memory.

    Eliminate the disk drive completely and use SSD memory.

    Control LCD display brightness to minimum acceptable.

    Turn off adapters like wifi if not in use.

    Reduce CPU Hertz to acceptable minimum, increase as needed for higher computational requirement (ie graphics)

    I was getting over 10 hours out of my 2-core, 4 GB laptop when I bought it new in 2009, so I am hardly surprised. Yes, I selected one that was expected to last long, but it also had a normal 500 GB HDD, as it was to be used for copying pictures from my camera in the woods. And it definitely worked as expected.

    I don't use a laptop, but I have wondered how various component functions consume battery power.....the graphs there give a nice quick overview....
