Hung Computer

If the computer does not turn off when you press the power button, the computer may be hung. Press and hold the power button until the computer turns off completely (this process may take several seconds). If the computer is hung and the power button fails to function properly, unplug the AC power cable from the computer, wait for the computer to completely stop running, and plug in the AC power cable. If the computer does not restart, press the power button to restart the computer.

Hyper-Threading

Hyper-Threading is an Intel® technology that can enhance overall computer performance by allowing one physical microprocessor to function as two logical microprocessors, capable of performing certain tasks simultaneously. It is recommended that you use the Microsoft® Windows® XP SP1 or later 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.
