Enabling Hyper-Threading Technology

Hyper-Threading Technology is a high performance technology, developed by Intel®, that allows a single processor to

execute multiple threads of instructions simultaneously. HT Technology enables the Intel processor to utilize its execution

resources more efficiently, delivering performance increases and improving user productivity. Not all system applications

benefit from the HT Technology. Not all systems support HT Technology.

To see if HT Technology can benefit you, test your system by turning the feature on. The Computer Setup (F10) menu

can be used to turn this feature on or off. To enter Computer Setup, during power up, wait for the prompt F10=setup

to appear on the lower right corner of the screen. After the prompt appears, press the F10 key to enter F10 setup. At

Computer Setup, select Advanced > Device Options > Hyper-Threading, then choose whether to enable or disable the

HT Technology.

NOTE:

If your workstation does not support HT Technology, the menu item will not be available on the Computer Setup

menu.

NOTE:

To enable HT Technology, Linux systems require the latest system BIOS and an SMP kernel (for systems installed

with a single processor). For additional information concerning the setup of

Linux–preinstalled or Linux–enabled workstations, refer to the HP User Manual for Linux, which is located at

www.hp.com/support/linux_user_manual.

NOTE:

HT Technology is only available on Intel-based systems.

For more information about the HT Technology, visit the Intel® Web site at www.intel.com.

Turning Off the Workstation

To properly turn off the workstation, first shut down the operating system software.

CAUTION:

Manually forcing the workstation off can cause loss of data.

To manually turn off power to the workstation, press and hold the power button for four seconds. However, manually

turning off the power bypasses the standby state and can result in loss of data.

To reconfigure the power button to work in On/Off mode, run Computer Setup (F10). For more information about using

Computer Setup, refer to the Service and Technical Reference Guide, which is available through a link on the

Documentation and Diagnostics CD (www.hp.com/support/workstation_manuals).
