Dell OpenManage Client Instrumentation
Dell OpenManage Client Instrumentation is software that enables remote
management programs such as IT Assistant to do the following:
• Access information about your computer, such as the number processors
installed and the computer’s operating system.
• Monitor the status of your computer, such as listening for thermal alerts
from temperature probes or hard drive failure alerts from storage devices.
• Change the state of your computer, such as updating the BIOS or shutting
down the computer remotely.
A managed system is one that has Dell OpenManage Client Instrumentation
set up on a network that uses IT Assistant. For information about Dell
OpenManage Client Instrumentation, see the Dell OpenManage Client
Instrumentation User’s Guide available on the Dell Support website at
support.dell.com.
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. Such periods of
reduced power are called sleep states.
• Standby (Windows XP): Power is reduced or turned off for most
components, including the cooling fans; however, system memory remains
active.
• Sleep (Windows Vista): Reduces power consumption to a minimum by
writing all data in system memory to a hard drive, and then turning off
power for most components. Writing the date to a hard drive ensures that
data is not lost if the computer loses power; however, system memory
remains active to increase the restart time for the computer.
• Hibernate: Reduces power consumption to a minimum by writing all data
in system memory to a hard drive, and then removing system power.
Waking the computer from Hibernate restarts the computer, and restores
the data stored in system memory. The computer then returns to the
operating state it was in prior to entering hibernation mode.
