Is CPU frequency scaling on? If not, this clearly explains it all for me.
For example, on my laptop :
$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

Next is the LCD backlight : is it at the same level in Linux as in
Windows? I know that on my laptop, I get one extra hour of battery
time by lowering the LCD brightness to the minimum.

Hoping to help,
