Windows XP Information
Each Windows Power Scheme will also adjust the processor performance of your machine in order to save pow-
er. This is worth bearing in mind if you are experiencing any reduced performance (especially under DC/battery
power).
Choose the Home/Office Desk scheme for maximum performance when the computer is powered from an AC
power source. Choose the Max Battery scheme (bear in mind that this scheme may slow down the overall per-
formance 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.
