Power management support

ACPI
APM
Microsoft recommends using ACPI instead of the earlier version of power management (APM) on Windows 2000
and Windows XP. All 2004 HP Compaq Business Desktop Computers with the Intel 915 Chipset include support for
ACPI and do not include support for the obsolete APM interface.

Hyper-Threaded processor support

Hyper-Thread Processor
Support

• Hyper-Threading makes a single physical Hyper-Thread enabled Pentium 4 processor appear as two logical
processors to the operating system.
• Due to application compatibility concerns, HP recommends Windows XP -SP1 or later be used when
Hyper-Threading is enabled. Some Linux versions also support Hyper-Thread.
• Windows 2000 supports up to two processors. Business Desktops do not support 2 processors.
• Optimizations for Hyper-Threading are not included in Windows 2000 Professional so performance will be lower
with Hyper-Threading enabled.
• Support for Hyper-Threading is available for both Windows XP Professional and Windows XP Home Edition.
Some Linux versions also support Hyper-Thread.
• Windows XP Home Edition provides support for one physical processor.
• Windows XP Professional provides support for one or two physical processors.
