Acer C720: Is it worth to turn off unused devices?

[Matthew Dillon]

You can buy a cheap watt meter on amazon and measure whether it makes a
difference.  We've tried power savings modes for the Wifi but it didn't
have much of an impact.  The mouse pad and touch screen drivers already
have idle fallbacks which do a pretty good job.
