 Using powertop, you can get an idea of the power consumption of the various elements.
-<br>Getting it right is always a bit tricky as you've to make sure there is no other active elements than the ones you want to measure, especially check that the HDD is spin down (hdparm -C /dev/sda) and force it down without having to wait (hdparm -y /dev/sda).

 <br>Measurements are not per sub-system but the total power consumption, then only you can approximate what's the diff when feature is on/off, and for basis X=(LCD_off, WiFi_off) you've to find it from A=(LCD_on, WiFi_off), B=(LCD_off,WiFi_on) and C=(LCD_on,WiFi_on): X=A-(C-B)
