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 (see
). These periods of reduced
power are called "sleep modes."
NOTE:
All components installed in the computer must support the hibernate and/or standby mode feature(s) and have
the appropriate drivers loaded to enter either of these sleep modes. For more information, see the manufacturer's
documentation for each component.
Standby
. In this sleep mode, power is reduced or turned off for most components, including the cooling fans. However,
system memory remains active.
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.
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 (see
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.
