Power Schemes
You can set your computer to conserve power through individual components by
means of Power Schemes. You can also adjust the settings for each scheme to set the
monitor to turn off after a specified time, and the computer’s hard disk motor to turn
off if the hard disk drive has not been accessed for a specified period of time (if the
system reads or writes data, the hard disk motor will be turned back on). The schemes
may also be set to set a specified time for the system to enter Stand by or Hibernate
modes.
Figure 3 - 1 Power Schemes
Each Windows Power Scheme will also adjust the processor performance of your
machine in order to save power. This is worth bearing in mind if you are experienc¬ing
any reduced performance (especially under DC/battery power).
Choose the Home/Office Desk scheme for maximum performance when the com¬puter
is powered from an AC power source. Choose the Max Battery scheme (bear in mind
that this scheme may slow down the overall performance of the computer in order
to save power) for maximum power saving when the computer is battery (DC power)
powered.
Windows will use Portable/Laptop as the default scheme.
