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. 40 Advanced Features
