Power Management Features D - 15
D
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 experien cing 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 th e 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 comp uter 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 compu ter ’s operation and restart where you left off. This sy s-
tem 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
If you want to stay away from your work for just a while, you can put the system on Stand by instead of in hi-
bernation. It takes a longer time to wake up the system from Hibernate mode than from Stand by mode.
