5.5.1. Minimising power consumption
One of the best ways to minimise power consumption is to turn-off the LCD panel and it’s
backlight when the display is not needed. To do this in Windows XP (it is similar in other
operating systems):
 From the Windows Start menu, select Control Panel. Then double-click on the
Display item.
 Select the Screen Saver tab.
 Press the Power button.
 Set Turn-off monitor to a suitable period of time, such as After 5 mins or After
10 mins. This sets the duration of time of keyboard, mouse or touch screen
inactivity after which the display is turned off.
 In the Screen Saver tab, there is a Screen saver item. Setting this to (None) also
reduces power consumption – the screen saver display still runs, even though the
display is off (therefore the CPU is being used, which consumes power).
