3.8 Enabling Hyper-Threading Technology
HT 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.
To enable HT Technology:
• 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.
OR
• If you have HP Cool Tools (available on some HP Workstations), click the HP Cool Tools icon, select
HP Protect Tools Security Manager, select BIOS Configuration, click the Advanced tab, click
Device Options and enable Hyper-Threading.
If the HP Cool Tools icon is not on your desktop, click Start > All Programs > HP Cool Tools > HP
Protect Tools Security Manager. Within HP Protect Tools Security Manager, select BIOS Configuration,
click the Advanced tab, click Device Options and enable Hyper-Threading.
NOTE: If your workstation does not support HT Technology, the menu item will not be available on the Computer Setup
menu.
NOTE: HT Technology is only available with select Intel processors.
For more information about the HT Technology, visit the Intel Web site at www.intel.com.
3.9 Using Energy Star
The Energy Star® program, a government-backed initiative, promotes energy efficiency by identifying ways to reduce
energy consumption at home or in the office. Some HP Workstations may be configured to follow Energy Star guidelines
for power consumption.
For those workstations supporting Energy Star and have it enabled, the power management features will be set as
follows:
• Monitor—goes into Standby mode after 20 minutes of inactivity.
• System—goes into Standby mode after 20 minutes of inactivity.
• Hard Drive—goes into power savings mode after the system goes into Standby mode.
NOTE: If you have to restore the operating system, Energy Star settings (if applicable) will need to be reset after the
restore.
NOTE: For information on resetting Energy Star settings, 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).
