Windows XP Information
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 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 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.
System Power Options
You can use the system power options to stop the computer’s operation and restart where you left off. This system features Stand by and Hibernate sleep mode levels (Hibernate mode will need to be enabled by clicking
the option in the Hibernate tab in the Power Options control panel).
Hibernate Mode vs. Shutdown
Hibernate mode and Shutdown are the same in that the system is off and you need to press the power button to
turn it on. When you come back from hibernation, you can return to where you last left off (what was on your
desktop) without reopening the application(s) and file(s) you last used.
Stand by Mode vs. Hibernate Mode
D
If you want to stay away from your work for just a while, you can put the system on Stand by instead of in hibernation. It takes a longer time to wake up the system from Hibernate mode than from Stand by mode.
