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 (OS) installed on your
computer and certain option settings in
Standby. In this sleep state, power to most components is reduced or turned off. However, system memory remains active.
l
This state is not supported by Windows NT 4.0.
Hibernate. This sleep state reduces power consumption to a minimum by writing all data in system memory to a hard drive and then removing system
l
power. Waking up from this state restarts the computer, and the memory contents are restored. Operation then resumes where the system left off
when it entered the hibernation state.
This state is supported by Windows 2000 and Windows XP only.
NOTE: All components installed in the computer must support this feature and have the appropriate drivers loaded to enter hibernation. For more
information, see the manufacturer's documentation for each component.
Shutdown. This sleep state removes all power from the system except a small auxiliary amount. As long as the computer remains connected to an
l
electrical outlet, it can be automatically or remotely started. For example, the Auto Power On feature allows the computer to automatically start at a time
you specify in system setup. Also, your network administrator can remotely start your computer using a power management event (PME) such as access
through a network connection (Wakeup On LAN).
The following table lists the sleep states available for each operating system as well as the methods you can use to "wake up" from each state.
