4. Using the Notebook PC
Standby Mode
In addition to reducing the CPU clock, this mode puts devices including the LCD backlight in their
lower active state. The Notebook PC enters Standby mode when the system remains idle for a specified
amount of time. The timeout can be set through the BIOS Setup. To resume system operation, press any
key on the keyboard, touchpad, or external mouse (or moving the mouse).
A Customized Power-Saving Example
The timeout settings for System Standby, Auto Suspend, Hard Disk Off, and Video Off specify the
amount of time the system must be inactive before the next power management level is enabled. The
example below demonstrates this function. The following power management events will take place if:
• The Hard Disk Timeout is set to 2 minutes
• The Standby Timeout to 8 minutes
• Auto Suspend Timeout to 10 minutes
1. After 2 minutes of system idle, the hard disk spins down.
2. After 6 additional minutes (a total of 8 minutes of system idle) the system enters Standby.
3. After 2 minutes in the system Standby mode (a total of 10 minutes of system idle), the system
suspends to memory or to disk (depending on BIOS setup).
After the system has suspended (see ENTRY EVENT below), operation can be returned or resumed
(see EXIT EVENT below) to the point in your application where it was suspended.
