11/7    hola, will going from 512mb -> 1gb of memory in my laptop
        significantly affect battery life? 5% less? -10%? --psb
        \_ Don't forget that DRAM refresh cycles also consume energy.
        \_ it will most likely increase battery life if it reduces swapping.
           if it doesn't, what's the point of upgrading?
           \_ what if 512 MB is insufficient only 5% of the time?
        \_ Depends on what you call significant.  If you're on the wire most
           of the time, no.  If you want to do serious traveling then 512mb
           is already too much.
           \- re: memory energy consumption [and attendant cooling demands]
              is why i asked. in re: swap/no swap ... gee maybe i need
              the memory to avoid heavy swapping when plugged in and
              doing a lot of photoediting ... and i dont want to take
              the extra memory out before going "unplugged". and the
              "depends what you call sig" person isnt saying anything
              at all. does anyone actually have a sense if memory is
              like 5% of total system power demand or more ... vs.
              lcd, and cpu. --psb
              \_ Dude, look up the power consumption needs of your chips and
                 do the math.  No one is giving you solid numbers because they
                 will vary dramatically by system.  I have a sense you don't
                 even know what you're trying to ask.
        \_ I have a 600MHz iBook with 640MB of RAM. It runs for 4 hours
           on battery easily. Decreasing LCD brightness tends to increse the
           run time by 25% or so. Does anyone have a similar model with smaller
           amount of memory? How much run time do you get on battery power?
           \- usually a little under 3hrs. i usually run the screen pretty
              bright. 800mhz titanium with 512mb. i am guessing the memory
              wont be a big deal then. --psb
              \_ Let us know after you shell out a few bucks since you're
                 unwilling to use google and a 4 function calculator.

        when the maximum resolution of my monitor changes? When I
        use my laptop, my emacs is too big (and I can't resize it
        because the bottom-right corner is not accessible).

           from WinXP to Win7 a few months ago.  Our products now primarily
