Hyper-Threading

Hyper-Threading is an Intel
one physical processor to function as two logical processors, capable of performing certain tasks
simultaneously. It is recommended that you use the Microsoft
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:
Click the Start button, right-click My Computer, and then click Properties.

Power Management

Your computer can be set to use less power when you are not working. You control the power usage
through the operating system installed on your computer and certain option settings in system setup.
These periods of reduced power are called "sleep modes."
NOTE:
All components installed in the computer must support the hibernate and/or standby mode
feature(s) and have the appropriate drivers loaded to enter either of these sleep modes. For more
information, see the manufacturer's documentation for each component.
Standby. In this sleep mode, power is reduced or turned off for most components, including the
cooling fans. However, system memory remains active.
Hibernate. This sleep mode 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 mode
restarts the computer, and the memory contents are restored. Operation then resumes where the
computer left off when it entered the hibernation mode.
