Living Room / Re: better battery life out of a laptop

2 points to consider-

1- Re IainB's post - the cap from Hard Disk Sentinel
  Required Power  for spinup -
the value shown is the Current [milliAmps] the actual Power, for a 5 Volt laptop Hard disk, would be 4.7 Watts.
 -- [ Power is Voltage X Current ] --  940 mA = 0.94 A   so   0.94 A x 5 V = 4.7 W

2- Re the posts about setting Background/Foreground colours to Dark/Light would only apply to LED screens,
as LCD screens use a fluorescent or LED backlight which would use the same Power, depending on brightness.
  There is a difference between LED Screens & LED Backlit LCD screens
