"sleep states":
Standby
. In this sleep state, power is reduced or turned off for most components, including the cooling fans. However,
system memory remains active.
NOTE:
All components installed in the computer must support this feature and have the appropriate drivers loaded to
enter standby. For more information, see the manufacturer's documentation for each component.
Hibernate
. This sleep state reduces power consumption to a minimum by writing all data in system memory to a hard
drive and then removing system power. Waking up from this state restarts the computer, and the memory contents
are restored. Operation then resumes where the computer left off when it entered the hibernation state.
NOTE:
All components installed in the computer must support this feature and have the appropriate drivers loaded to
enter hibernation. For more information, see the manufacturer's documentation for each component.
Shutdown
. This sleep state removes all power from the computer except a small auxiliary amount. As long as the
computer remains connected to an electrical outlet, it can be automatically or remotely started. For example, the Auto
Power On option in
system setup
allows the computer to automatically start at a specified time. Also, your network
administrator can remotely start your computer using a power management event such as Remote Wake Up.
The following table lists the sleep states and the methods you can use to wake the computer from each state.

Hyper-Threading
Hyper-Threading is an Intel® technology that can enhance overall computer performance by allowing one physical processor
to function as two logical processors, capable of performing certain tasks simultaneously. It is recommended that you use the
Microsoft® Windows® XP Service Pack 1 (SP1) or higher operating system because Windows XP is optimized to take
advantage of Hyper-Threading technology. While many programs can benefit from Hyper-Threading, some programs have not
been optimized for Hyper-Threading and may require an update from the software manufacturer. Contact the software
manufacturer for updates and information about using Hyper-Threading with your software.
To determine if your computer is using Hyper-Threading technology:
1. Click the
Start
button, right-click
My Computer
, and then click
Properties
.
2. Click
Hardware
and click
Device Manager
.
