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
. These periods of reduced power are called "sleep modes."
l
Standby
. In this sleep mode, power is reduced or turned off for most components, including the cooling fans. However, system memory remains active.
l
Hibernate
. This sleep mode reduces power consumption to a minimum by writing all data in system memory to a hard drive and then removing system
power. Waking up from this mode restarts the computer, and the memory contents are restored. Operation then resumes where the computer left off
when it entered the hibernation mode.
l
Shutdown
. This sleep mode removes all power from the computer except a small auxiliary amount. As long as the computer remains connected to an
electrical outlet, it can be automatically or remotely started. For example, the
Auto Power On
option in
system setup
allows the computer to
automatically start at a specified time. Also, your network administrator can remotely start your computer using a power management event such as
Remote Wake Up.
The following table lists the sleep modes and the methods you can use to wake the computer from each mode.
