The power-saving operations performed by the computer in each of these modes are summarized in the table below. Power-saving operations Mode* Function CPU Standby Reduces the CPU speed and the power used by CPU-related components Global Standby Reduces the CPU speed and the power used by CPU-related components; places peripheral components such as the hard disk, LCD screen, and screen backlight in their lowest active states Suspend to Memory Shuts off power to the CPU and DMA clocks; turns off the video and all other controllable peripheral devices Suspend to Disk Turns off all system logic, except for the system wakeup circuitry and battery charger; the system and video memory contents are saved to a file in one contiguous space on the hard disk for later restoration * As Dower-saving increases, response time decreases. Power-saving increases with each mode listed. CPU Standby saves the least amount of power, while Suspend to Disk mode saves the most. You can enable any or all of these power saving modes by using a combination of automatic and manual power management features, as described in the next sections. Note You can use all of the computer's power management features in conjunction with the Intel®/ Microsoft Advanced Power Management (APM) interface, version 1.0 or higher. This interface is provided with Windows and may be provided with other software on your system. See "Using the APM Interface" on page 3-15 for more information about how APM works along with your computer's power management features. Powering the Computer 3-11

The power-saving operations performed by the computer in
each of these modes are summarized in the table below.
Power-saving operations
Mode*
CPU Standby
Global Standby
Suspend to Memory
Suspend to Disk
Function
Reduces the CPU speed and the power used by
CPU-related components
Reduces the CPU speed and the power used by
CPU-related components; places peripheral
components such as the hard disk, LCD screen,
and screen backlight in their lowest active states
Shuts off power to the CPU and DMA clocks; turns
off the video and all other controllable peripheral
devices
Turns off all system logic, except for the system
wakeup circuitry and battery charger; the system
and video memory contents are saved to a file in
one contiguous space on the hard disk for later
restoration
* As Dower-saving increases, response time decreases. Power-saving
increases with each mode listed. CPU Standby saves the least amount of
power, while Suspend to Disk mode saves the most.
You can enable any or all of these power saving modes by
using a combination of automatic and manual power
management features, as described in the next sections.
Note
You can use all of the computer’s power management
features in conjunction with the Intel
®
/ Microsoft Advanced
Power Management (APM) interface, version 1.0 or higher.
This interface is provided with Windows and may be
provided with other software on your system. See “Using
the APM Interface” on page 3-15 for more information about
how APM works along with your computer’s power
management
features.
